-Common Properties for Display Panel
-===================================
-
-This document defines device tree properties common to several classes of
-display panels. It doesn't constitue a device tree binding specification by
-itself but is meant to be referenced by device tree bindings.
-
-When referenced from panel device tree bindings the properties defined in this
-document are defined as follows. The panel device tree bindings are
-responsible for defining whether each property is required or optional.
-
-
-Descriptive Properties
-----------------------
-
-- width-mm,
-- height-mm: The width-mm and height-mm specify the width and height of the
- physical area where images are displayed. These properties are expressed in
- millimeters and rounded to the closest unit.
-
-- label: The label property specifies a symbolic name for the panel as a
- string suitable for use by humans. It typically contains a name inscribed on
- the system (e.g. as an affixed label) or specified in the system's
- documentation (e.g. in the user's manual).
-
- If no such name exists, and unless the property is mandatory according to
- device tree bindings, it shall rather be omitted than constructed of
- non-descriptive information. For instance an LCD panel in a system that
- contains a single panel shall not be labelled "LCD" if that name is not
- inscribed on the system or used in a descriptive fashion in system
- documentation.
-
-
-Display Timings
----------------
-
-- panel-timing: Most display panels are restricted to a single resolution and
- require specific display timings. The panel-timing subnode expresses those
- timings as specified in the timing subnode section of the display timing
- bindings defined in
- Documentation/devicetree/bindings/display/panel/display-timing.txt.
-
-
-Connectivity
-------------
-
-- ports: Panels receive video data through one or multiple connections. While
- the nature of those connections is specific to the panel type, the
- connectivity is expressed in a standard fashion using ports as specified in
- the device graph bindings defined in
- Documentation/devicetree/bindings/graph.txt.
-
-- ddc-i2c-bus: Some panels expose EDID information through an I2C-compatible
- bus such as DDC2 or E-DDC. For such panels the ddc-i2c-bus contains a
- phandle to the system I2C controller connected to that bus.
-
-
-Control I/Os
-------------
-
-Many display panels can be controlled through pins driven by GPIOs. The nature
-and timing of those control signals are device-specific and left for panel
-device tree bindings to specify. The following GPIO specifiers can however be
-used for panels that implement compatible control signals.
-
-- enable-gpios: Specifier for a GPIO connected to the panel enable control
- signal. The enable signal is active high and enables operation of the panel.
- This property can also be used for panels implementing an active low power
- down signal, which is a negated version of the enable signal. Active low
- enable signals (or active high power down signals) can be supported by
- inverting the GPIO specifier polarity flag.
-
- Note that the enable signal control panel operation only and must not be
- confused with a backlight enable signal.
-
-- reset-gpios: Specifier for a GPIO coonnected to the panel reset control
- signal. The reset signal is active low and resets the panel internal logic
- while active. Active high reset signals can be supported by inverting the
- GPIO specifier polarity flag.
-
-Power
------
-
-- power-supply: display panels require power to be supplied. While several
- panels need more than one power supply with panel-specific constraints
- governing the order and timings of the power supplies, in many cases a single
- power supply is sufficient, either because the panel has a single power rail,
- or because all its power rails can be driven by the same supply. In that case
- the power-supply property specifies the supply powering the panel as a phandle
- to a regulator.
-
-Backlight
----------
-
-Most display panels include a backlight. Some of them also include a backlight
-controller exposed through a control bus such as I2C or DSI. Others expose
-backlight control through GPIO, PWM or other signals connected to an external
-backlight controller.
-
-- backlight: For panels whose backlight is controlled by an external backlight
- controller, this property contains a phandle that references the controller.

+description: |
+ This document defines device tree properties common to several classes of
+ display panels. It doesn't constitue a device tree binding specification by
+ itself but is meant to be referenced by device tree bindings.
+
+ When referenced from panel device tree bindings the properties defined in this
+ document are defined as follows. The panel device tree bindings are
+ responsible for defining whether each property is required or optional.
+
+properties:
+ # Descriptive Properties
+ width-mm:
+ description:
+ Specifies the width of the physical area where images are displayed. This

+ height-mm:
+ description:
+ Specifies the height of the physical area where images are displayed. This
+ property is expressed in millimeters and rounded to the closest unit.
+
+ label:
+ description: |
+ The label property specifies a symbolic name for the panel as a
+ string suitable for use by humans. It typically contains a name inscribed
+ on the system (e.g. as an affixed label) or specified in the system's
+ documentation (e.g. in the user's manual).
+
+ If no such name exists, and unless the property is mandatory according to
+ device tree bindings, it shall rather be omitted than constructed of
+ non-descriptive information. For instance an LCD panel in a system that
+ contains a single panel shall not be labelled "LCD" if that name is not
+ inscribed on the system or used in a descriptive fashion in system
+ documentation.

-TPO TPG110 Panel
-================
-
-This panel driver is a component that acts as an intermediary
-between an RGB output and a variety of panels. The panel
-driver is strapped up in electronics to the desired resolution
-and other properties, and has a control interface over 3WIRE
-SPI. By talking to the TPG110 over SPI, the strapped properties
-can be discovered and the hardware is therefore mostly
-self-describing.
-
- +--------+
-SPI -> | TPO | -> physical display
-RGB -> | TPG110 |
- +--------+
-
-If some electrical strap or alternate resolution is desired,
-this can be set up by taking software control of the display
-over the SPI interface. The interface can also adjust
-for properties of the display such as gamma correction and
-certain electrical driving levels.
-
-The TPG110 does not know the physical dimensions of the panel
-connected, so this needs to be specified in the device tree.
-
-It requires a GPIO line for control of its reset line.
-
-The serial protocol has line names that resemble I2C but the
-protocol is not I2C but 3WIRE SPI.
-
-Required properties:
-- compatible : one of:
- "ste,nomadik-nhk15-display", "tpo,tpg110"
- "tpo,tpg110"
-- grestb-gpios : panel reset GPIO
-- width-mm : see display/panel/panel-common.txt
-- height-mm : see display/panel/panel-common.txt
-
-The device needs to be a child of an SPI bus, see
-spi/spi-bus.txt. The SPI child must set the following
-properties:
-- spi-3wire
-- spi-max-frequency = <3000000>;
-as these are characteristics of this device.
-
-The device node can contain one 'port' child node with one child
-'endpoint' node, according to the bindings defined in
-media/video-interfaces.txt. This node should describe panel's video bus.
-
-Example
--------
-
-panel: display@0 {
- compatible = "tpo,tpg110";
- reg = <0>;
- spi-3wire;
- /* 320 ns min period ~= 3 MHz */
- spi-max-frequency = <3000000>;
- /* Width and height from data sheet */
- width-mm = <116>;
- height-mm = <87>;
- grestb-gpios = <&foo_gpio 5 GPIO_ACTIVE_LOW>;
- backlight = <&bl>;
-
- port {
- nomadik_clcd_panel: endpoint {
- remote-endpoint = <&foo>;
- };
- };
-};

created for the OPTIMUS range of multi-gpu platforms. To userspace PRIME
buffers are dma-buf based file descriptors.
-Overview and Driver Interface
------------------------------
+Overview and Lifetime Rules
+---------------------------
-Similar to GEM global names, PRIME file descriptors are also used to
-share buffer objects across processes. They offer additional security:
-as file descriptors must be explicitly sent over UNIX domain sockets to
-be shared between applications, they can't be guessed like the globally
-unique GEM names.
-
-Drivers that support the PRIME API must set the DRIVER_PRIME bit in the
-struct :c:type:`struct drm_driver <drm_driver>`
-driver_features field, and implement the prime_handle_to_fd and
-prime_fd_to_handle operations.
-
-int (\*prime_handle_to_fd)(struct drm_device \*dev, struct drm_file
-\*file_priv, uint32_t handle, uint32_t flags, int \*prime_fd); int
-(\*prime_fd_to_handle)(struct drm_device \*dev, struct drm_file
-\*file_priv, int prime_fd, uint32_t \*handle); Those two operations
-convert a handle to a PRIME file descriptor and vice versa. Drivers must
-use the kernel dma-buf buffer sharing framework to manage the PRIME file
-descriptors. Similar to the mode setting API PRIME is agnostic to the
-underlying buffer object manager, as long as handles are 32bit unsigned
-integers.
-
-While non-GEM drivers must implement the operations themselves, GEM
-drivers must use the :c:func:`drm_gem_prime_handle_to_fd()` and
-:c:func:`drm_gem_prime_fd_to_handle()` helper functions. Those
-helpers rely on the driver gem_prime_export and gem_prime_import
-operations to create a dma-buf instance from a GEM object (dma-buf
-exporter role) and to create a GEM object from a dma-buf instance
-(dma-buf importer role).
-
-struct dma_buf \* (\*gem_prime_export)(struct drm_device \*dev,
-struct drm_gem_object \*obj, int flags); struct drm_gem_object \*
-(\*gem_prime_import)(struct drm_device \*dev, struct dma_buf
-\*dma_buf); These two operations are mandatory for GEM drivers that
-support PRIME.

PRIME Helper Functions
----------------------
Also read the :ref:`guidelines for the kernel documentation at large <doc_guide>`.
+Documentation Requirements for kAPI
+-----------------------------------
+
+All kernel APIs exported to other modules must be documented, including their
+datastructures and at least a short introductory section explaining the overall
+concepts. Documentation should be put into the code itself as kerneldoc comments
+as much as reasonable.
+
+Do not blindly document everything, but document only what's relevant for driver
+authors: Internal functions of drm.ko and definitely static functions should not
+have formal kerneldoc comments. Use normal C comments if you feel like a comment
+is warranted. You may use kerneldoc syntax in the comment, but it shall not
+start with a /** kerneldoc marker. Similar for data structures, annotate
+anything entirely private with ``/* private: */`` comments as per the
+documentation guide.

Getting Started
===============
A lot of drivers forward gem mmap calls to dma-buf mmap for imported buffers.
And also a lot of them forward dma-buf mmap to the gem mmap implementations.
-Would be great to refactor this all into a set of small common helpers.
+There's drm_gem_prime_mmap() for this now, but still needs to be rolled out.
Contact: Daniel Vetter

-Defaults for .gem_prime_import and export
------------------------------------------
-
-Most drivers don't need to set drm_driver->gem_prime_import and
-->gem_prime_export now that drm_gem_prime_import() and drm_gem_prime_export()
-are the default.
-
struct drm_gem_object_funcs
---------------------------
GEM objects can now have a function table instead of having the callbacks on the
DRM driver struct. This is now the preferred way and drivers can be moved over.
-DRM_GEM_CMA_VMAP_DRIVER_OPS, DRM_GEM_SHMEM_DRIVER_OPS already support this, but
-DRM_GEM_VRAM_DRIVER_PRIME does not yet and needs to be aligned with the previous
-two. We also need a 2nd version of the CMA define that doesn't require the
+We also need a 2nd version of the CMA define that doesn't require the
vmapping to be present (different hook for prime importing). Plus this needs to
be rolled out to all drivers using their own implementations, too.
Contact: Daniel Vetter
-Add missing kerneldoc for exported functions
---------------------------------------------
-
-The DRM reference documentation is still lacking kerneldoc in a few areas. The
-task would be to clean up interfaces like moving functions around between
-files to better group them and improving the interfaces like dropping return
-values for functions that never fail. Then write kerneldoc for all exported
-functions and an overview section and integrate it all into the drm book.
-
-See https://dri.freedesktop.org/docs/drm/ for what's there already.

-Contact: Daniel Vetter
-
Make panic handling work
------------------------
this (together with the drm_minor->drm_device move) would allow us to remove
debugfs_init.
+- Drop the return code and error checking from all debugfs functions. Greg KH is
+ working on this already.
+
Contact: Daniel Vetter
KMS cleanups
Contact: Daniel Vetter
+Backlight Refactoring
+---------------------
+
+Backlight drivers have a triple enable/disable state, which is a bit overkill.
+Plan to fix this:
+
+1. Roll out backlight_enable() and backlight_disable() helpers everywhere. This
+ has started already.
+2. In all, only look at one of the three status bits set by the above helpers.
+3. Remove the other two status bits.
+

Driver Specific
===============
Tinydrm is the helper driver for really simple fb drivers. The goal is to make
those drivers as simple as possible, so lots of room for refactoring:
-- backlight helpers, probably best to put them into a new drm_backlight.c.
- This is because drivers/video is de-facto unmaintained. We could also
- move drivers/video/backlight to drivers/gpu/backlight and take it all
- over within drm-misc, but that's more work. Backlight helpers require a fair
- bit of reworking and refactoring. A simple example is the enabling of a backlight.
- Tinydrm has helpers for this. It would be good if other drivers can also use the
- helper. However, there are various cases we need to consider i.e different
- drivers seem to have different ways of enabling/disabling a backlight.
- We also need to consider the backlight drivers (like gpio_backlight). The situation
- is further complicated by the fact that the backlight is tied to fbdev
- via fb_notifier_callback() which has complicated logic. For further details, refer
- to the following discussion thread:
- https://groups.google.com/forum/#!topic/outreachy-kernel/8rBe30lwtdA
-
- spi helpers, probably best put into spi core/helper code. Thierry said
the spi maintainer is fast&reactive, so shouldn't be a big issue.

- * DMA-BUF/GEM Object references and lifetime overview:
- *
- * On the export the dma_buf holds a reference to the exporting GEM
- * object. It takes this reference in handle_to_fd_ioctl, when it
- * first calls .prime_export and stores the exporting GEM object in
- * the dma_buf priv. This reference needs to be released when the
- * final reference to the &dma_buf itself is dropped and its
- * &dma_buf_ops.release function is called. For GEM-based drivers,
- * the dma_buf should be exported using drm_gem_dmabuf_export() and
- * then released by drm_gem_dmabuf_release().
- *
- * On the import the importing GEM object holds a reference to the
- * dma_buf (which in turn holds a ref to the exporting GEM object).
- * It takes that reference in the fd_to_handle ioctl.
- * It calls dma_buf_get, creates an attachment to it and stores the
- * attachment in the GEM object. When this attachment is destroyed
- * when the imported object is destroyed, we remove the attachment
- * and drop the reference to the dma_buf.
- *
- * When all the references to the &dma_buf are dropped, i.e. when
- * userspace has closed both handles to the imported GEM object (through the
- * FD_TO_HANDLE IOCTL) and closed the file descriptor of the exported
- * (through the HANDLE_TO_FD IOCTL) dma_buf, and all kernel-internal references
- * are also gone, then the dma_buf gets destroyed. This can also happen as a
- * part of the clean up procedure in the drm_release() function if userspace
- * fails to properly clean up. Note that both the kernel and userspace (by
- * keeeping the PRIME file descriptors open) can hold references onto a
- * &dma_buf.
- *
- * Thus the chain of references always flows in one direction
- * (avoiding loops): importing_gem -> dmabuf -> exporting_gem
- *
- * Self-importing: if userspace is using PRIME as a replacement for flink
- * then it will get a fd->handle request for a GEM object that it created.
- * Drivers should detect this situation and return back the gem object
- * from the dma-buf private. Prime will do this automatically for drivers that
- * use the drm_gem_prime_{import,export} helpers.
- *
- * GEM struct &dma_buf_ops symbols are now exported. They can be resued by
- * drivers which implement GEM interface.
+/**
+ * DOC: overview and lifetime rules
+ *
+ * Similar to GEM global names, PRIME file descriptors are also used to share
+ * buffer objects across processes. They offer additional security: as file
+ * descriptors must be explicitly sent over UNIX domain sockets to be shared
+ * between applications, they can't be guessed like the globally unique GEM
+ * names.
+ *
+ * Drivers that support the PRIME API implement the
+ * &drm_driver.prime_handle_to_fd and &drm_driver.prime_fd_to_handle operations.
+ * GEM based drivers must use drm_gem_prime_handle_to_fd() and
+ * drm_gem_prime_fd_to_handle() to implement these. For GEM based drivers the
+ * actual driver interfaces is provided through the &drm_gem_object_funcs.export
+ * and &drm_driver.gem_prime_import hooks.
+ *
+ * &dma_buf_ops implementations for GEM drivers are all individually exported
+ * for drivers which need to overwrite or reimplement some of them.
+ *
+ * Reference Counting for GEM Drivers
+ * ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ *
+ * On the export the &dma_buf holds a reference to the exported buffer object,
+ * usually a &drm_gem_object. It takes this reference in the PRIME_HANDLE_TO_FD
+ * IOCTL, when it first calls &drm_gem_object_funcs.export
+ * and stores the exporting GEM object in the &dma_buf.priv field. This
+ * reference needs to be released when the final reference to the &dma_buf
+ * itself is dropped and its &dma_buf_ops.release function is called. For
+ * GEM-based drivers, the &dma_buf should be exported using
+ * drm_gem_dmabuf_export() and then released by drm_gem_dmabuf_release().
+ *
+ * Thus the chain of references always flows in one direction, avoiding loops:
+ * importing GEM object -> dma-buf -> exported GEM bo. A further complication
+ * are the lookup caches for import and export. These are required to guarantee
+ * that any given object will always have only one uniqe userspace handle. This
+ * is required to allow userspace to detect duplicated imports, since some GEM
+ * drivers do fail command submissions if a given buffer object is listed more
+ * than once. These import and export caches in &drm_prime_file_private only
+ * retain a weak reference, which is cleaned up when the corresponding object is
+ * released.
+ *
+ * Self-importing: If userspace is using PRIME as a replacement for flink then
+ * it will get a fd->handle request for a GEM object that it created. Drivers
+ * should detect this situation and return back the underlying object from the
+ * dma-buf private. For GEM based drivers this is handled in
+ * drm_gem_prime_import() already.
