-* Rockchip RK3188/RK3066 Clock and Reset Unit
-
-The RK3188/RK3066 clock controller generates and supplies clock to various
-controllers within the SoC and also implements a reset controller for SoC
-peripherals.
-
-Required Properties:
-
-- compatible: should be "rockchip,rk3188-cru", "rockchip,rk3188a-cru" or
- "rockchip,rk3066a-cru"
-- reg: physical base address of the controller and length of memory mapped
- region.
-- #clock-cells: should be 1.
-- #reset-cells: should be 1.
-
-Optional Properties:
-
-- rockchip,grf: phandle to the syscon managing the "general register files"
- If missing pll rates are not changable, due to the missing pll lock status.
-
-Each clock is assigned an identifier and client nodes can use this identifier
-to specify the clock which they consume. All available clocks are defined as
-preprocessor macros in the dt-bindings/clock/rk3188-cru.h and
-dt-bindings/clock/rk3066-cru.h headers and can be used in device tree sources.
-Similar macros exist for the reset sources in these files.
-
-External clocks:
-
-There are several clocks that are generated outside the SoC. It is expected
-that they are defined using standard clock bindings with following
-clock-output-names:
- - "xin24m" - crystal input - required,
- - "xin32k" - rtc clock - optional,
- - "xin27m" - 27mhz crystal input on rk3066 - optional,
- - "ext_hsadc" - external HSADC clock - optional,
- - "ext_cif0" - external camera clock - optional,
- - "ext_rmii" - external RMII clock - optional,
- - "ext_jtag" - externalJTAG clock - optional
-
-Example: Clock controller node:
-
- cru: cru@20000000 {
- compatible = "rockchip,rk3188-cru";
- reg = <0x20000000 0x1000>;
- rockchip,grf = <&grf>;
-
- #clock-cells = <1>;
- #reset-cells = <1>;
- };
-
-Example: UART controller node that consumes the clock generated by the clock
- controller:
-
- uart0: serial@10124000 {
- compatible = "snps,dw-apb-uart";
- reg = <0x10124000 0x400>;
- interrupts = <GIC_SPI 34 IRQ_TYPE_LEVEL_HIGH>;
- reg-shift = <2>;
- reg-io-width = <1>;

-Device Tree Clock bindings for arch-rockchip
-
-This binding uses the common clock binding[1].
-
-[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-== Gate clocks ==
-
-These bindings are deprecated!
-Please use the soc specific CRU bindings instead.
-
-The gate registers form a continuos block which makes the dt node
-structure a matter of taste, as either all gates can be put into
-one gate clock spanning all registers or they can be divided into
-the 10 individual gates containing 16 clocks each.
-The code supports both approaches.
-
-Required properties:
-- compatible : "rockchip,rk2928-gate-clk"
-- reg : shall be the control register address(es) for the clock.
-- #clock-cells : from common clock binding; shall be set to 1
-- clock-output-names : the corresponding gate names that the clock controls
-- clocks : should contain the parent clock for each individual gate,
- therefore the number of clocks elements should match the number of
- clock-output-names
-

-* Rockchip Pinmux Controller
-
-The Rockchip Pinmux Controller, enables the IC
-to share one PAD to several functional blocks. The sharing is done by
-multiplexing the PAD input/output signals. For each PAD there are several
-muxing options with option 0 being the use as a GPIO.
-
-Please refer to pinctrl-bindings.txt in this directory for details of the
-common pinctrl bindings used by client devices, including the meaning of the
-phrase "pin configuration node".
-
-The Rockchip pin configuration node is a node of a group of pins which can be
-used for a specific device or function. This node represents both mux and
-config of the pins in that group. The 'pins' selects the function mode(also
-named pin mode) this pin can work on and the 'config' configures various pad
-settings such as pull-up, etc.
-
-The pins are grouped into up to 5 individual pin banks which need to be
-defined as gpio sub-nodes of the pinmux controller.
-
-Required properties for iomux controller:
- - compatible: one of "rockchip,rk2928-pinctrl", "rockchip,rk3066a-pinctrl"
- "rockchip,rk3066b-pinctrl", "rockchip,rk3188-pinctrl"
- "rockchip,rk3288-pinctrl"
- - rockchip,grf: phandle referencing a syscon providing the
- "general register files"
-
-Optional properties for iomux controller:
- - rockchip,pmu: phandle referencing a syscon providing the pmu registers
- as some SoCs carry parts of the iomux controller registers there.
- Required for at least rk3188 and rk3288.
-
-Deprecated properties for iomux controller:
- - reg: first element is the general register space of the iomux controller
- It should be large enough to contain also separate pull registers.
- second element is the separate pull register space of the rk3188.
- Use rockchip,grf and rockchip,pmu described above instead.
-
-Required properties for gpio sub nodes:
- - compatible: "rockchip,gpio-bank"
- - reg: register of the gpio bank (different than the iomux registerset)
- - interrupts: base interrupt of the gpio bank in the interrupt controller
- - clocks: clock that drives this bank
- - gpio-controller: identifies the node as a gpio controller and pin bank.
- - #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
- binding is used, the amount of cells must be specified as 2. See generic
- GPIO binding documentation for description of particular cells.
- - interrupt-controller: identifies the controller node as interrupt-parent.
- - #interrupt-cells: the value of this property should be 2 and the interrupt
- cells should use the standard two-cell scheme described in
- bindings/interrupt-controller/interrupts.txt
-
-Deprecated properties for gpio sub nodes:
- - compatible: "rockchip,rk3188-gpio-bank0"
- - reg: second element: separate pull register for rk3188 bank0, use
- rockchip,pmu described above instead
-
-Required properties for pin configuration node:
- - rockchip,pins: 3 integers array, represents a group of pins mux and config
- setting. The format is rockchip,pins = <PIN_BANK PIN_BANK_IDX MUX &phandle>.
- The MUX 0 means gpio and MUX 1 to N mean the specific device function.
- The phandle of a node containing the generic pinconfig options
- to use, as described in pinctrl-bindings.txt in this directory.
