-Allwinner Reduced Serial Bus (RSB) controller
-
-The RSB controller found on later Allwinner SoCs is an SMBus like 2 wire
-serial bus with 1 master and up to 15 slaves. It is represented by a node
-for the controller itself, and child nodes representing the slave devices.
-
-Required properties :
-
- - reg : Offset and length of the register set for the controller.
- - compatible : Shall be "allwinner,sun8i-a23-rsb".
- - interrupts : The interrupt line associated to the RSB controller.
- - clocks : The gate clk associated to the RSB controller.
- - resets : The reset line associated to the RSB controller.
- - #address-cells : shall be 1
- - #size-cells : shall be 0
-
-Optional properties :
-
- - clock-frequency : Desired RSB bus clock frequency in Hz. Maximum is 20MHz.
- If not set this defaults to 3MHz.
-
-Child nodes:
-
-An RSB controller node can contain zero or more child nodes representing
-slave devices on the bus. Child 'reg' properties should contain the slave
-device's hardware address. The hardware address is hardwired in the device,
-which can normally be found in the datasheet.
-
-Example:
-
- rsb@1f03400 {
- compatible = "allwinner,sun8i-a23-rsb";
- reg = <0x01f03400 0x400>;
- interrupts = <0 39 4>;
- clocks = <&apb0_gates 3>;
- clock-frequency = <3000000>;
- resets = <&apb0_rst 3>;
- #address-cells = <1>;
- #size-cells = <0>;
-
- pmic@3e3 {
- compatible = "...";
- reg = <0x3e3>;
-
- /* ... */
- };
- };
Required properties:
- compatible : Shall contain one or more of
+ - "renesas,r8a774a1-hdmi" for R8A774A1 (RZ/G2M) compatible HDMI TX

+Qualcomm Always-On Subsystem side channel binding
+
+This binding describes the hardware component responsible for side channel
+requests to the always-on subsystem (AOSS), used for certain power management
+requests that is not handled by the standard RPMh interface. Each client in the
+SoC has it's own block of message RAM and IRQ for communication with the AOSS.
+The protocol used to communicate in the message RAM is known as Qualcomm
+Messaging Protocol (QMP)
+
+The AOSS side channel exposes control over a set of resources, used to control
+a set of debug related clocks and to affect the low power state of resources
+related to the secondary subsystems. These resources are exposed as a set of
+power-domains.
+
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be "qcom,sdm845-aoss-qmp"
+
+- reg:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: the base address and size of the message RAM for this
+ client's communication with the AOSS
+
+- interrupts:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: should specify the AOSS message IRQ for this client
+
+- mboxes:
+ Usage: required
+ Value type: <prop-encoded-array>
+ Definition: reference to the mailbox representing the outgoing doorbell
+ in APCS for this client, as described in mailbox/mailbox.txt
+
+- #clock-cells:
+ Usage: optional
+ Value type: <u32>
+ Definition: must be 0
+ The single clock represents the QDSS clock.
+
+- #power-domain-cells:
+ Usage: optional
+ Value type: <u32>
+ Definition: must be 1
+ The provided power-domains are:
+ CDSP state (0), LPASS state (1), modem state (2), SLPI
+ state (3), SPSS state (4) and Venus state (5).
+
+= SUBNODES
+The AOSS side channel also provides the controls for three cooling devices,
+these are expressed as subnodes of the QMP node. The name of the node is used
+to identify the resource and must therefor be "cx", "mx" or "ebi".
+
+- #cooling-cells:
+ Usage: optional
+ Value type: <u32>

+test client is interacted with through the debugfs filesystem:
+
+* *debugfs*/ntb\_tool/*hw*/
+ A directory in debugfs will be created for each
+ NTB device probed by the tool. This directory is shortened to *hw*
+ below.
+* *hw*/port
+ This file describes the local port number
+* *hw*/irq*_occurrences
+ One occurrences file exists for each interrupt and, when read,
+ returns the number of times the interrupt has been triggered.
+* *hw*/peer*/port
+ This file describes the port number for each peer
+* *hw*/peer*/count
+ This file describes the number of interrupts that can be
+ triggered on each peer
+* *hw*/peer*/trigger
+ Writing an interrupt number (any number less than the value

+ * - On cheza we want to be able to hook DP up to _either_ of the

+ * - When you configure a Type C port for 4 lanes of DP you lose USB3.
+ * - In order to make everything work, the native Type C port is always
+ * configured as 4-lanes DP so it's always available.
+ * - The extra USB3 port on SDM845 goes to a USB 3 hub which is then
+ * sent to the two Type C connectors.
+ * - The extra USB2 lines from the native Type C port are always
+ * setup as "peripheral" so that we can mux them over to one connector
+ * or the other if someone needs the connector configured as a gadget
+ * (but they only get USB2 speeds).
+ *
+ * All the hardware muxes would allow us to hook things up in different
+ * ways to some potential benefit for static configurations (you could
+ * achieve extra USB2 bandwidth by using two different ports for the
+ * two conenctors or possibly even get USB3 peripheral mode), but in

+ * Errata:
+ * When CPU raise #NPF on guest data access and vCPU CR4.SMAP=1, it is
+ * possible that CPU microcode implementing DecodeAssist will fail
+ * to read bytes of instruction which caused #NPF. In this case,
+ * GuestIntrBytes field of the VMCB on a VMEXIT will incorrectly
+ * return 0 instead of the correct guest instruction bytes.
+ *
+ * This happens because CPU microcode reading instruction bytes
+ * uses a special opcode which attempts to read data using CPL=0
+ * priviledges. The microcode reads CS:RIP and if it hits a SMAP
+ * fault, it gives up and returns no instruction bytes.
+ *
+ * Detection:
+ * We reach here in case CPU supports DecodeAssist, raised #NPF and
+ * returned 0 in GuestIntrBytes field of the VMCB.
+ * First, errata can only be triggered in case vCPU CR4.SMAP=1.
+ * Second, if vCPU CR4.SMEP=1, errata could only be triggered
+ * in case vCPU CPL==3 (Because otherwise guest would have triggered
+ * a SMEP fault instead of #NPF).
+ * Otherwise, vCPU CR4.SMEP=0, errata could be triggered by any vCPU CPL.
+ * As most guests enable SMAP if they have also enabled SMEP, use above
+ * logic in order to attempt minimize false-positive of detecting errata
+ * while still preserving all cases semantic correctness.
+ *
+ * Workaround:
+ * To determine what instruction the guest was executing, the hypervisor
+ * will have to decode the instruction at the instruction pointer.
*
* In non SEV guest, hypervisor will be able to read the guest
* memory to decode the instruction pointer when insn_len is zero
* instruction pointer so we will not able to workaround it. Lets
* print the error and request to kill the guest.

+ * The keyboard and touchpad controller on the MacBookAir6, MacBookPro12,
+ * MacBook8 and newer can be driven either by USB or SPI. However the USB
+ * pins are only connected on the MacBookAir6 and 7 and the MacBookPro12.
+ * All others need this driver. The interface is selected using ACPI methods:
+ *
+ * * UIEN ("USB Interface Enable"): If invoked with argument 1, disables SPI
+ * and enables USB. If invoked with argument 0, disables USB.
+ * * UIST ("USB Interface Status"): Returns 1 if USB is enabled, 0 otherwise.
+ * * SIEN ("SPI Interface Enable"): If invoked with argument 1, disables USB
+ * and enables SPI. If invoked with argument 0, disables SPI.
+ * * SIST ("SPI Interface Status"): Returns 1 if SPI is enabled, 0 otherwise.
+ * * ISOL: Resets the four GPIO pins used for SPI. Intended to be invoked with
+ * argument 1, then once more with argument 0.
+ *
+ * UIEN and UIST are only provided on models where the USB pins are connected.
+ *
+ * SPI-based Protocol
+ * ------------------
+ *
+ * The device and driver exchange messages (struct message); each message is
+ * encapsulated in one or more packets (struct spi_packet). There are two types
+ * of exchanges: reads, and writes. A read is signaled by a GPE, upon which one
+ * message can be read from the device. A write exchange consists of writing a
+ * command message, immediately reading a short status packet, and then, upon
+ * receiving a GPE, reading the response message. Write exchanges cannot be
+ * interleaved, i.e. a new write exchange must not be started till the previous
+ * write exchange is complete. Whether a received message is part of a read or
+ * write exchange is indicated in the encapsulating packet's flags field.
+ *
+ * A single message may be too large to fit in a single packet (which has a
+ * fixed, 256-byte size). In that case it will be split over multiple,
+ * consecutive packets.

- Add the option -fno-inline-functions-called-once to gcc commands.
When inlining a function annotated with __init in a non-init
function, we would lose the section information and thus
the analysis would not catch the illegal reference.
This option tells gcc to inline less (but it does result in
a larger kernel).
