[PATCH v3 0/3] clk: rockchip: support clk controller for RK3128 SoC

[Elaine Zhang]

The driver and clk ID\SRST ID it's also applies to the RK3126 SoC.

change in V3:
export clk ID for usb480m and usb480m_phy

change in V2:
rename the rk312x to rk3128.

[PATCH v3 1/3] clk: rockchip: add dt-binding header for rk3128

[Elaine Zhang]

Add the dt-bindings header for the rk3128,
that gets shared between the clock controller and
the clock references in the dts.
Add softreset ID for rk3128.
And it also applies to the RK3126 SoC.

We probably don't need the clock-id for USB480M_PHY, as it is an external
clock and is unused. Instead as I wrote in the previous patch, it should
be added to the list of external clocks in the binding txt document.

+* 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>;
+		clock-frequency = <24000000>;
+		clocks = <&cru SCLK_UART2>, <&cru PCLK_UART2>;
+		clock-names = "sclk_uart", "pclk_uart";
+	};
