For the PRCM CCUs on H3/A64, one more clock is needed:

For the PRCM CCUs on H3/A64, two more clocks are needed:

- "pll-periph": the SoC's peripheral PLL from the main CCU

- "iosc": the SoC's internal frequency oscillator

Example for generic CCU:

r_ccu: clock@01f01400 {

	compatible = "allwinner,sun50i-a64-r-ccu";

	reg = <0x01f01400 0x100>;

	clocks = <&osc24M>, <&osc32k>, <&iosc>;

	clock-names = "hosc", "losc", "iosc";

	clocks = <&osc24M>, <&osc32k>, <&iosc>, <&ccu CLK_PLL_PERIPH0>;

	clock-names = "hosc", "losc", "iosc", "pll-periph";

	#clock-cells = <1>;

	#reset-cells = <1>;

};

Optional properties:

In order to use the GPIO lines in PWM mode, some additional optional

properties are required. Only Armada 370 and XP support these properties.
