Subject: [PATCH v2 0/2] arm64: dts: rockchip: Add pwm nodes for RK3528

Add pwm nodes for RK3528. Most rk3528 boards use pwm-regulator to
supply to CPU, add node to enable them. The PWM core on RK3528 is
the same as RK3328, but the driver doesn't support interrupts yet.

Note that pwm regulator needs to be initialized in U-Boot:
```
&vdd_arm {
	regulator-init-microvolt = <953000>;
};

&vdd_logic {
	regulator-init-microvolt = <900000>;
};
```

Changes in v2:
  Remove merged bindings patch
  Remove pwm pinctrl in rk3528.dtsi
  Enable pwm regulator for Radxa E20C
