rk3399 — pvtm dts配置

1、pvtm简介：

PVTM(Process-Voltage-Temperature Monitor) 是用来监测由处理器，电压和温度引起的芯片性能变化。

2、属性值配置：

- compatible: 可以配置成以下值：
 - "rockchip,px30-pvtm" - for PX30 SoCs.
 - "rockchip,px30-pmu-pvtm" - for PX30 SoCs.
 - "rockchip,rk3288-pvtm" - for RK3288 SoCs.
 - "rockchip,rk3308-pvtm" - for RK3308 SoCs.
 - "rockchip,rk3308-pmu-pvtm" - for RK3308 SoCs.
 - "rockchip,rk3366-pvtm" - for RK3366 SoCs.
 - "rockchip,rk3366-pmu-pvtm" - for RK3366 SoCs.
 - "rockchip,rk3399-pvtm" - for RK3399 SoCs.
 - "rockchip,rk3399-pmu-pvtm" - for RK3399 SoCs.
- clocks:配置pvtm的时钟；
- clock-names: 时钟名称配置成："core_l", "core_b", "gpu", "ddr" 和 "pmu".
- resets: 配置pvtm的复位控制器
- reset-names: 复拉控制器的名称可以配置成："core_l", "core_b", "gpu", "ddr" and "pmu".

3、以rk3399为例：

grf: syscon@ff770000 {
	compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
	reg = <0x0 0xff770000 0x0 0x10000>;
	#address-cells = <1>;
	#size-cells = <1>;

...

	pvtm: pvtm {
		compatible = "rockchip,rk3399-pvtm";
		clocks = <&cru SCLK_PVTM_CORE_L>, <&cru SCLK_PVTM_CORE_B>,
			 <&cru SCLK_PVTM_GPU>, <&cru SCLK_PVTM_DDR>;
		clock-names = "core_l", "core_b", "gpu", "ddr";
		resets = <&cru SRST_PVTM_CORE_L>, <&cru SRST_PVTM_CORE_B>,
			 <&cru SRST_PVTM_GPU>, <&cru SRST_PVTM_DDR>;
		reset-names = "core_l", "core_b", "gpu", "ddr";
	};
