+* Rockchip RK3128 Clock and Reset Unit
+
+The RK3128 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,rk3128-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 changeable, 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/rk3128-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,
+ - "ext_i2s" - external I2S clock - optional,
+ - "gmac_clkin" - external GMAC clock - optional
+
+Example: Clock controller node:
+
+ cru: cru@20000000 {
+ compatible = "rockchip,rk3128-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:
+
+ uart2: serial@20068000 {
+ compatible = "rockchip,serial";
+ reg = <0x20068000 0x100>;
+ interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;

+Texas Instruments TI-SCI Clocks
+===============================
+
+All clocks on Texas Instruments' SoCs that contain a System Controller,
+are only controlled by this entity. Communication between a host processor
+running an OS and the System Controller happens through a protocol known
+as TI-SCI[1]. This clock implementation plugs into the common clock
+framework and makes use of the TI-SCI protocol on clock API requests.
+
+[1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
+
+Required properties:
+-------------------
+- compatible: Must be "ti,k2g-sci-clk"
+- #clock-cells: Shall be 2.
+ In clock consumers, this cell represents the device ID and clock ID
+ exposed by the PM firmware. The assignments can be found in the header
+ files <dt-bindings/genpd/<soc>.h> (which covers the device IDs) and
+ <dt-bindings/clock/<soc>.h> (which covers the clock IDs), where <soc>
+ is the SoC involved, for example 'k2g'.
+
+Examples:
+--------
+
+pmmc: pmmc {
+ compatible = "ti,k2g-sci";
+
+ k2g_clks: clocks {
+ compatible = "ti,k2g-sci-clk";
+ #clock-cells = <2>;
+ };
+};
+
+uart0: serial@2530c00 {
+ compatible = "ns16550a";
+ clocks = <&k2g_clks 0x2c 0>;
+};

+Texas Instruments clkctrl clock binding
+
+Texas Instruments SoCs can have a clkctrl clock controller for each
+interconnect target module. The clkctrl clock controller manages functional
+and interface clocks for each module. Each clkctrl controller can also
+gate one or more optional functional clocks for a module, and can have one
+or more clock muxes. There is a clkctrl clock controller typically for each
+interconnect target module on omap4 and later variants.
+
+The clock consumers can specify the index of the clkctrl clock using
+the hardware offset from the clkctrl instance register space. The optional
+clocks can be specified by clkctrl hardware offset and the index of the
+optional clock.
+
+For more information, please see the Linux clock framework binding at
+Documentation/devicetree/bindings/clock/clock-bindings.txt.
+
+Required properties :
+- compatible : shall be "ti,clkctrl"
+- #clock-cells : shall contain 2 with the first entry being the instance
+ offset from the clock domain base and the second being the
+ clock index
+
+Example: Clock controller node on omap 4430:
+
+&cm2 {
+ l4per: cm@1400 {
+ cm_l4per@0 {
+ cm_l4per_clkctrl: clk@20 {
+ compatible = "ti,clkctrl";
+ reg = <0x20 0x1b0>;
+ #clock-cells = <2>;
+ };
+ };
+ };
+};
+
+Example: Preprocessor helper macros in dt-bindings/clock/ti-clkctrl.h
+
+#define OMAP4_CLKCTRL_OFFSET 0x20
+#define OMAP4_CLKCTRL_INDEX(offset) ((offset) - OMAP4_CLKCTRL_OFFSET)
+#define MODULEMODE_HWCTRL 1
+#define MODULEMODE_SWCTRL 2
+
+#define OMAP4_GPTIMER10_CLKTRL OMAP4_CLKCTRL_INDEX(0x28)
+#define OMAP4_GPTIMER11_CLKTRL OMAP4_CLKCTRL_INDEX(0x30)
+#define OMAP4_GPTIMER2_CLKTRL OMAP4_CLKCTRL_INDEX(0x38)
+...
+#define OMAP4_GPIO2_CLKCTRL OMAP_CLKCTRL_INDEX(0x60)
+
+Example: Clock consumer node for GPIO2:
+
+&gpio2 {
+ clocks = <&cm_l4per_clkctrl OMAP4_GPIO2_CLKCTRL 0
+ &cm_l4per_clkctrl OMAP4_GPIO2_CLKCTRL 8>;
+};
Required properties:
-- compatible : Should be "marvell,orion-gpio", "marvell,mv78200-gpio"
- or "marvell,armadaxp-gpio". "marvell,orion-gpio" should be used for
- Orion, Kirkwood, Dove, Discovery (except MV78200) and Armada
- 370. "marvell,mv78200-gpio" should be used for the Discovery
- MV78200. "marvel,armadaxp-gpio" should be used for all Armada XP
- SoCs (MV78230, MV78260, MV78460).

+ (MV78230, MV78260, MV78460).
+

+ and
+ Documentation/devicetree/bindings/arm/marvell/ap806-system-controller.txt
+ for specific details about the offset property.
- reg: Address and length of the register set for the device. Only one
entry is expected, except for the "marvell,armadaxp-gpio" variant
for which two entries are expected: one for the general registers,
- one for the per-cpu registers.
