+Amlogic Meson8 and Meson8b power-management-unit:
+-------------------------------------------------
+
+The pmu is used to turn off and on different power domains of the SoCs
+This includes the power to the CPU cores.
+
+Required node properties:
+- compatible value : depending on the SoC this should be one of:
+ "amlogic,meson8-pmu"
+ "amlogic,meson8b-pmu"
+- reg : physical base address and the size of the registers window
+
+Example:
+
+ pmu@c81000e4 {
+ compatible = "amlogic,meson8b-pmu", "syscon";
+ reg = <0xc81000e0 0x18>;
+ };
--- /dev/null
+Amlogic Meson8 and Meson8b SRAM for smp bringup:
+------------------------------------------------
+
+Amlogic's SMP-capable SoCs use part of the sram for the bringup of the cores.
+Once the core gets powered up it executes the code that is residing at a
+specific location.
+
+Therefore a reserved section sub-node has to be added to the mmio-sram
+declaration.
+
+Required sub-node properties:
+- compatible : depending on the SoC this should be one of:
+ "amlogic,meson8-smp-sram"
+ "amlogic,meson8b-smp-sram"
+
+The rest of the properties should follow the generic mmio-sram discription
+found in ../../misc/sram.txt
+
+Example:
+
+ sram: sram@d9000000 {
+ compatible = "mmio-sram";
+ reg = <0xd9000000 0x20000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0xd9000000 0x20000>;
+
+ smp-sram@1ff80 {
+ compatible = "amlogic,meson8b-smp-sram";
+ reg = <0x1ff80 0x8>;
+ };

+Texas Instruments sysc interconnect target module wrapper binding
+
+Texas Instruments SoCs can have a generic interconnect target module
+hardware for devices connected to various interconnects such as L3
+interconnect (Arteris NoC) and L4 interconnect (Sonics s3220). The sysc
+is mostly used for interaction between module and PRCM. It participates
+in the OCP Disconnect Protocol but other than that is mostly independent
+of the interconnect.
+
+Each interconnect target module can have one or more devices connected to
+it. There is a set of control registers for managing interconnect target
+module clocks, idle modes and interconnect level resets for the module.
+
+These control registers are sprinkled into the unused register address
+space of the first child device IP block managed by the interconnect
+target module and typically are named REVISION, SYSCONFIG and SYSSTATUS.
+
+Required standard properties:
+
+- compatible shall be one of the following generic types:
+
+ "ti,sysc-omap2"
+ "ti,sysc-omap4"
+ "ti,sysc-omap4-simple"
+
+ or one of the following derivative types for hardware
+ needing special workarounds:
+
+ "ti,sysc-omap3430-sr"
+ "ti,sysc-omap3630-sr"
+ "ti,sysc-omap4-sr"
+ "ti,sysc-omap3-sham"
+ "ti,sysc-omap-aes"
+ "ti,sysc-mcasp"
+ "ti,sysc-usb-host-fs"
+
+- reg shall have register areas implemented for the interconnect
+ target module in question such as revision, sysc and syss
+
+- reg-names shall contain the register names implemented for the
+ interconnect target module in question such as
+ "rev, "sysc", and "syss"
+
+- ranges shall contain the interconnect target module IO range
+ available for one or more child device IP blocks managed
+ by the interconnect target module, the ranges may include
+ multiple ranges such as device L4 range for control and
+ parent L3 range for DMA access
+
+Optional properties:
+
+- clocks clock specifier for each name in the clock-names as
+ specified in the binding documentation for ti-clkctrl,
+ typically available for all interconnect targets on TI SoCs
+ based on omap4 except if it's read-only register in hwauto
+ mode as for example omap4 L4_CFG_CLKCTRL
+
+- clock-names should contain at least "fck", and optionally also "ick"
+ depending on the SoC and the interconnect target module
+
+- ti,hwmods optional TI interconnect module name to use legacy
+ hwmod platform data
+
+
+Example: Single instance of MUSB controller on omap4 using interconnect ranges
+using offsets from l4_cfg second segment (0x4a000000 + 0x80000 = 0x4a0ab000):
+
+ target-module@2b000 { /* 0x4a0ab000, ap 84 12.0 */
+ compatible = "ti,sysc-omap2";
+ ti,hwmods = "usb_otg_hs";
+ reg = <0x2b400 0x4>,
+ <0x2b404 0x4>,
+ <0x2b408 0x4>;
+ reg-names = "rev", "sysc", "syss";
+ clocks = <&l3_init_clkctrl OMAP4_USB_OTG_HS_CLKCTRL 0>;
+ clock-names = "fck";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x2b000 0x1000>;
+
+ usb_otg_hs: otg@0 {
+ compatible = "ti,omap4-musb";
+ reg = <0x0 0x7ff>;
+ interrupts = <GIC_SPI 92 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 93 IRQ_TYPE_LEVEL_HIGH>;
+ usb-phy = <&usb2_phy>;
+ ...
+ };
+ };
+
+Note that other SoCs, such as am335x can have multipe child devices. On am335x
+there are two MUSB instances, two USB PHY instances, and a single CPPI41 DMA
+instance as children of a single interconnet target module.
Required properties:
- compatible : Should be of the form "ti,emif-<ip-rev>" where <ip-rev>
- is the IP revision of the specific EMIF instance.
- For am437x should be ti,emif-am4372.
+ is the IP revision of the specific EMIF instance. For newer controllers,
+ compatible should be one of the following:
+ "ti,emif-am3352"
+ "ti,emif-am4372"
- phy-type : <u32> indicating the DDR phy type. Following are the
allowed values

+Texas Instruments SmartReflex binding
+
+SmartReflex is used to set and adjust the SoC operating points.
+
+
+Required properties:
+
+compatible: Shall be one of the following:
+ "ti,omap3-smartreflex-core"
+ "ti,omap3-smartreflex-iva"
+ "ti,omap4-smartreflex-core"
+ "ti,omap4-smartreflex-mpu"
+ "ti,omap4-smartreflex-iva"
+
+reg: Shall contain the device instance IO range
+
+interrupts: Shall contain the device instance interrupt
+
+
+Optional properties:
+
+ti,hwmods: Shall contain the TI interconnect module name if needed
+ by the SoC
+
+
+Example:
+
+ smartreflex_iva: smartreflex@4a0db000 {
+ compatible = "ti,omap4-smartreflex-iva";
+ reg = <0x4a0db000 0x80>;
+ interrupts = <GIC_SPI 102 IRQ_TYPE_LEVEL_HIGH>;

- * The V3 PCI interface chip in Integrator provides several windows from
- * local bus memory into the PCI memory areas. Unfortunately, there
- * are not really enough windows for our usage, therefore we reuse
- * one of the windows for access to PCI configuration space. The
- * memory map is as follows:
- *
- * Local Bus Memory Usage
- *
- * 40000000 - 4FFFFFFF PCI memory. 256M non-prefetchable
- * 50000000 - 5FFFFFFF PCI memory. 256M prefetchable
- * 60000000 - 60FFFFFF PCI IO. 16M
- * 61000000 - 61FFFFFF PCI Configuration. 16M
- *
- * There are three V3 windows, each described by a pair of V3 registers.
- * These are LB_BASE0/LB_MAP0, LB_BASE1/LB_MAP1 and LB_BASE2/LB_MAP2.
- * Base0 and Base1 can be used for any type of PCI memory access. Base2
- * can be used either for PCI I/O or for I20 accesses. By default, uHAL
- * uses this only for PCI IO space.
- *
- * Normally these spaces are mapped using the following base registers:
- *
- * Usage Local Bus Memory Base/Map registers used
- *
- * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
- * Mem 50000000 - 5FFFFFFF LB_BASE1/LB_MAP1
- * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
- * Cfg 61000000 - 61FFFFFF
- *
- * This means that I20 and PCI configuration space accesses will fail.
- * When PCI configuration accesses are needed (via the uHAL PCI
- * configuration space primitives) we must remap the spaces as follows:
- *
- * Usage Local Bus Memory Base/Map registers used
- *
- * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
- * Mem 50000000 - 5FFFFFFF LB_BASE0/LB_MAP0
- * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
- * Cfg 61000000 - 61FFFFFF LB_BASE1/LB_MAP1
- *
- * To make this work, the code depends on overlapping windows working.
- * The V3 chip translates an address by checking its range within
- * each of the BASE/MAP pairs in turn (in ascending register number
- * order). It will use the first matching pair. So, for example,
- * if the same address is mapped by both LB_BASE0/LB_MAP0 and
- * LB_BASE1/LB_MAP1, the V3 will use the translation from
- * LB_BASE0/LB_MAP0.
- *
- * To allow PCI Configuration space access, the code enlarges the
- * window mapped by LB_BASE0/LB_MAP0 from 256M to 512M. This occludes
- * the windows currently mapped by LB_BASE1/LB_MAP1 so that it can
- * be remapped for use by configuration cycles.
- *
- * At the end of the PCI Configuration space accesses,
- * LB_BASE1/LB_MAP1 is reset to map PCI Memory. Finally the window
- * mapped by LB_BASE0/LB_MAP0 is reduced in size from 512M to 256M to
- * reveal the now restored LB_BASE1/LB_MAP1 window.
- *
- * NOTE: We do not set up I2O mapping. I suspect that this is only
- * for an intelligent (target) device. Using I2O disables most of
- * the mappings into PCI memory.
