[PATCH v1 1/3] clk: rockchip: add dt-binding header for rk312x

[Elaine Zhang]

Add the dt-bindings header for the rk312x, that gets shared between
the clock controller and the clock references in the dts.
Add softreset ID for rk312x.

+* Rockchip RK312X Clock and Reset Unit
+
+The RK312X 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,rk312x-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/rk312x-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 {

+
+		#clock-cells = <1>;
+		#reset-cells = <1>;

+Example: UART controller node that consumes the clock generated by the clock
+  controller:
+
+uart2: serial@20068000 {

+		interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;

please no placeholders in dt-things. So while rk312x may be ok on the driver 
side, it is not for devicetree things and especially compatible properties.

I haven't even found out for which soc this is, so if it's for the rk3128 for 
example, please just name it accordingly.

So ideally, just name _everything_ (compatible, dt-header file, driver, 
everything) after the first soc it should support and we'll see later on, if it 
matches for other socs as well.


Thanks
Heiko
