+Marvell Armada AP806 System Controller
+======================================
+
+The AP806 is one of the two core HW blocks of the Marvell Armada 7K/8K
+SoCs. It contains a system controller, which provides a number
+registers giving access to numerous features: clocks, pin-muxing and
+many other SoC configuration items. This DT binding allows to describe
+this system controller.
+
+The Device Tree node representing the AP806 system controller provides
+a number of clocks:
+
+ - 0: clock of CPU cluster 0
+ - 1: clock of CPU cluster 1
+ - 2: fixed PLL at 1200 Mhz
+ - 3: MSS clock, derived from the fixed PLL
+
+Required properties:
+
+ - compatible: must be:
+ "marvell,ap806-system-controller", "syscon"
+ - reg: register area of the AP806 system controller
+ - #clock-cells: must be set to 1
+ - clock-output-names: must be defined to:
+ "ap-cpu-cluster-0", "ap-cpu-cluster-1", "ap-fixed", "ap-mss"
+
+Example:
+
+ syscon: system-controller@6f4000 {
+ compatible = "marvell,ap806-system-controller", "syscon";
+ #clock-cells = <1>;
+ clock-output-names = "ap-cpu-cluster-0", "ap-cpu-cluster-1",
+ "ap-fixed", "ap-mss";
+ reg = <0x6f4000 0x1000>;
+ };

+* Clock bindings for Axis ARTPEC-6 chip
+
+The bindings are based on the clock provider binding in
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+External clocks:
+----------------
+
+There are two external inputs to the main clock controller which should be
+provided using the common clock bindings.
+- "sys_refclk": External 50 Mhz oscillator (required)
+- "i2s_refclk": Alternate audio reference clock (optional).
+
+Main clock controller
+---------------------
+
+Required properties:
+- #clock-cells: Should be <1>
+ See dt-bindings/clock/axis,artpec6-clkctrl.h for the list of valid identifiers.
+- compatible: Should be "axis,artpec6-clkctrl"
+- reg: Must contain the base address and length of the system controller
+- clocks: Must contain a phandle entry for each clock in clock-names
+- clock-names: Must include the external oscillator ("sys_refclk"). Optional
+ ones are the audio reference clock ("i2s_refclk") and the audio fractional
+ dividers ("frac_clk0" and "frac_clk1").
+
+Examples:
+
+ext_clk: ext_clk {
+ #clock-cells = <0>;
+ compatible = "fixed-clock";
+ clock-frequency = <50000000>;
+};
+
+clkctrl: clkctrl@f8000000 {
+ #clock-cells = <1>;
+ compatible = "axis,artpec6-clkctrl";
+ reg = <0xf8000000 0x48>;
+ clocks = <&ext_clk>;
+ clock-names = "sys_refclk";

+Oxford Semiconductor OXNAS SoC Family Standard Clocks
+================================================
+
+Please also refer to clock-bindings.txt in this directory for common clock
+bindings usage.
+
+Required properties:
+- compatible: Should be "oxsemi,ox810se-stdclk"
+- #clock-cells: 1, see below
+
+Parent node should have the following properties :
+- compatible: Should be "oxsemi,ox810se-sys-ctrl", "syscon", "simple-mfd"
+
+For OX810SE, the clock indices are :
+ - 0: LEON

+ - 2: CIPHER
+ - 3: SATA
+ - 4: AUDIO
+ - 5: USBMPH
+ - 6: ETHA

+* Rockchip RK3399 Clock and Reset Unit
+
+The RK3399 clock controller generates and supplies clock to various
+controllers within the SoC and also implements a reset controller for SoC
+peripherals.
+
+Required Properties:
+
+- compatible: PMU for CRU should be "rockchip,rk3399-pmucru"
+- compatible: CRU should be "rockchip,rk3399-cru"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- #clock-cells: should be 1.
+- #reset-cells: should be 1.
+
+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/rk3399-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,
+ - "clkin_gmac" - external GMAC clock - optional,
+ - "clkin_i2s" - external I2S clock - optional,
+ - "pclkin_cif" - external ISP clock - optional,
+ - "clk_usbphy0_480m" - output clock of the pll in the usbphy0
+ - "clk_usbphy1_480m" - output clock of the pll in the usbphy1
+
+Example: Clock controller node:
+
+ pmucru: pmu-clock-controller@ff750000 {
+ compatible = "rockchip,rk3399-pmucru";
+ reg = <0x0 0xff750000 0x0 0x1000>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+ cru: clock-controller@ff760000 {
+ compatible = "rockchip,rk3399-cru";
+ reg = <0x0 0xff760000 0x0 0x1000>;
+ #clock-cells = <1>;
+ #reset-cells = <1>;
+ };
+
+Example: UART controller node that consumes the clock generated by the clock
+ controller:
+
+ uart0: serial@ff1a0000 {
+ compatible = "rockchip,rk3399-uart", "snps,dw-apb-uart";
+ reg = <0x0 0xff180000 0x0 0x100>;
+ clocks = <&cru SCLK_UART0>, <&cru PCLK_UART0>;
+ clock-names = "baudclk", "apb_pclk";
+ interrupts = <GIC_SPI 99 IRQ_TYPE_LEVEL_HIGH>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ };
