+
+Power management
+----------------
+
+For power management (particularly, S2/S3/S5 system suspend), the following SoC
+components are needed:
+
+= Always-On control block (AON CTRL)
+
+This hardware provides control registers for the "always-on" (even in low-power
+modes) hardware, such as the Power Management State Machine (PMSM).
+
+Required properties:
+- compatible : should be one of
+ "brcm,bcm7425-aon-ctrl"
+ "brcm,bcm7429-aon-ctrl"
+ "brcm,bcm7435-aon-ctrl" and
+ "brcm,brcmstb-aon-ctrl"
+- reg : the register start and length for the AON CTRL block
+
+Example:
+
+syscon@410000 {
+ compatible = "brcm,bcm7425-aon-ctrl", "brcm,brcmstb-aon-ctrl";
+ reg = <0x410000 0x400>;
+};
+
+= Memory controllers
+
+A Broadcom STB SoC typically has a number of independent memory controllers,
+each of which may have several associated hardware blocks, which are versioned
+independently (control registers, DDR PHYs, etc.). One might consider
+describing these controllers as a parent "memory controllers" block, which
+contains N sub-nodes (one for each controller in the system), each of which is
+associated with a number of hardware register resources (e.g., its PHY.
+
+== MEMC (MEMory Controller)
+
+Represents a single memory controller instance.
+
+Required properties:
+- compatible : should contain "brcm,brcmstb-memc" and "simple-bus"
+- ranges : should contain the child address in the parent address
+ space, must be 0 here, and the register start and length of
+ the entire memory controller (including all sub nodes: DDR PHY,
+ arbiter, etc.)
+- #address-cells : must be 1
+- #size-cells : must be 1
+
+Example:
+
+ memory-controller@0 {
+ compatible = "brcm,brcmstb-memc", "simple-bus";
+ ranges = <0x0 0x0 0xa000>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ memc-arb@1000 {
+ ...
+ };
+
+ memc-ddr@2000 {
+ ...
+ };
+
+ ddr-phy@6000 {
+ ...
+ };
+ };
+
+Should contain subnodes for any of the following relevant hardware resources:
+
+== DDR PHY control
+
+Control registers for this memory controller's DDR PHY.
+
+Required properties:
+- compatible : should contain one of these
+ "brcm,brcmstb-ddr-phy-v64.5"
+ "brcm,brcmstb-ddr-phy"
+
+- reg : the DDR PHY register range and length
+
+Example:
+
+ ddr-phy@6000 {
+ compatible = "brcm,brcmstb-ddr-phy-v64.5";
+ reg = <0x6000 0xc8>;
+ };
+
+== DDR memory controller sequencer
+
+Control registers for this memory controller's DDR memory sequencer
+
+Required properties:
+- compatible : should contain one of these
+ "brcm,bcm7425-memc-ddr"
+ "brcm,bcm7429-memc-ddr"
+ "brcm,bcm7435-memc-ddr" and
+ "brcm,brcmstb-memc-ddr"
+
+- reg : the DDR sequencer register range and length
+
+Example:
+
+ memc-ddr@2000 {
+ compatible = "brcm,bcm7425-memc-ddr", "brcm,brcmstb-memc-ddr";
+ reg = <0x2000 0x300>;
+ };
+
+== MEMC Arbiter
+
+The memory controller arbiter is responsible for memory clients allocation
+(bandwidth, priorities etc.) and needs to have its contents restored during
+deep sleep states (S3).
+
+Required properties:
+
+- compatible : should contain one of these
+ "brcm,brcmstb-memc-arb-v10.0.0.0"
+ "brcm,brcmstb-memc-arb"
+
+- reg : the DDR Arbiter register range and length
+
+Example:
+
+ memc-arb@1000 {
+ compatible = "brcm,brcmstb-memc-arb-v10.0.0.0";
+ reg = <0x1000 0x248>;
+ };
+
+== Timers
+
+The Broadcom STB chips contain a timer block with several general purpose
+timers that can be used.
+
+Required properties:
+
+- compatible : should contain one of:
+ "brcm,bcm7425-timers"
+ "brcm,bcm7429-timers"
+ "brcm,bcm7435-timers" and
+ "brcm,brcmstb-timers"
+- reg : the timers register range
+- interrupts : the interrupt line for this timer block
+
+Example:
+
+ timers: timer@4067c0 {
+ compatible = "brcm,bcm7425-timers", "brcm,brcmstb-timers";
+ reg = <0x4067c0 0x40>;

+MIPS CPU interrupt controller
+
+On MIPS the mips_cpu_irq_of_init() helper can be used to initialize the 8 CPU
+IRQs from a devicetree file and create a irq_domain for IRQ controller.
+
+With the irq_domain in place we can describe how the 8 IRQs are wired to the
+platforms internal interrupt controller cascade.
+
+Below is an example of a platform describing the cascade inside the devicetree
+and the code used to load it inside arch_init_irq().
+
+Required properties:
+- compatible : Should be "mti,cpu-interrupt-controller"
+
+Example devicetree:
+ cpu-irq: cpu-irq {
+ #address-cells = <0>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ compatible = "mti,cpu-interrupt-controller";
+ };
+
+ intc: intc@200 {
+ compatible = "ralink,rt2880-intc";
+ reg = <0x200 0x100>;
+
+ interrupt-controller;
+ #interrupt-cells = <1>;
+
+ interrupt-parent = <&cpu-irq>;
+ interrupts = <2>;
+ };
+
+
+Example platform irq.c:
+static struct of_device_id __initdata of_irq_ids[] = {
+ { .compatible = "mti,cpu-interrupt-controller", .data = mips_cpu_irq_of_init },
+ { .compatible = "ralink,rt2880-intc", .data = intc_of_init },
+ {},
+};
+
+void __init arch_init_irq(void)
+{
+ of_irq_init(of_irq_ids);
+}

+Imagination Pistachio SoC
+=========================
+
+Required properties:
+--------------------
+ - compatible: Must include "img,pistachio".
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Since the topology may
+be probed via CPS, it is not necessary to specify secondary CPUs. Required
+propertis:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mti,interaptiv".
+ - reg: CPU number.
+ - clocks: Must include the CPU clock. See ../../clock/clock-bindings.txt for
+ details on clock bindings.
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "mti,interaptiv";
+ reg = <0>;
+ clocks = <&clk_core CLK_MIPS>;
+ };
+ };
+
+
+Boot protocol:
+--------------
+In accordance with the MIPS UHI specification[1], the bootloader must pass the
+following arguments to the kernel:
+ - $a0: -2.
+ - $a1: KSEG0 address of the flattened device-tree blob.

+Imagination University Program MIPSfpga
+=======================================
+
+Under the Imagination University Program, a microAptiv UP core has been
+released for academic usage.
+
+As we are dealing with a MIPS core instantiated on an FPGA, specifications
+are fluid and can be varied in RTL.
+
+This binding document is provided as baseline guidance for the example
+project provided by IMG.
+
+The example project runs on the Nexys4DDR board by Digilent powered by
+the ARTIX-7 FPGA by Xilinx.
+
+Relevant details about the example project and the Nexys4DDR board:
+
+- microAptiv UP core m14Kc
+- 50MHz clock speed
+- 128Mbyte DDR RAM at 0x0000_0000
+- 8Kbyte RAM at 0x1000_0000
+- axi_intc at 0x1020_0000
+- axi_uart16550 at 0x1040_0000
+- axi_gpio at 0x1060_0000
+- axi_i2c at 0x10A0_0000
+- custom_gpio at 0x10C0_0000
+- axi_ethernetlite at 0x10E0_0000
+- 8Kbyte BootRAM at 0x1FC0_0000
+
+Required properties:
+--------------------
+ - compatible: Must include "digilent,nexys4ddr","img,xilfpga".
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Required properties:
+ - device_type: Must be "cpu".
+ - compatible: Must be "mips,m14Kc".
+ - reg: Must be <0>.
+ - clocks: phandle to ext clock for fixed-clock received by MIPS core.
+
+Example:
+
+ compatible = "img,xilfpga","digilent,nexys4ddr";
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ cpu0: cpu@0 {
+ device_type = "cpu";
+ compatible = "mips,m14Kc";
+ reg = <0>;
+ clocks = <&ext>;
+ };
+ };
+
+ ext: ext {
+ compatible = "fixed-clock";
+ #clock-cells = <0>;
+ clock-frequency = <50000000>;
+ };
+
+Boot protocol:
+--------------
+
+The BootRAM is a writeable "RAM" in FPGA at 0x1FC0_0000.
+This is for easy reprogrammibility via JTAG.
+
+The BootRAM initializes the cache and the axi_uart peripheral.
+
+DDR initialization is already handled by a HW IP block.
+
+When the example project bitstream is loaded, the cpu_reset button
+needs to be pressed.
+
+The bootram initializes the cache and axi_uart.
+Then outputs MIPSFPGA\n\r on the serial port on the Nexys4DDR board.
+
+At this point, the board is ready to load the Linux kernel
+vmlinux file via JTAG.

+Lantiq XWAY SoC RCU binding
+===========================
+
+This binding describes the RCU (reset controller unit) multifunction device,
+where each sub-device has it's own set of registers.
+
+The RCU register range is used for multiple purposes. Mostly one device
+uses one or multiple register exclusively, but for some registers some
+bits are for one driver and some other bits are for a different driver.
+With this patch all accesses to the RCU registers will go through
+syscon.
