* Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device
PRCM is an MFD device exposing several Power Management related devices
(like clks and reset controllers).
Required properties:
- compatible: "allwinner,sun6i-a31-prcm" or "allwinner,sun8i-a23-prcm"
- reg: The PRCM registers range
The prcm node may contain several subdevices definitions:
- see Documentation/devicetree/clk/sunxi.txt for clock devices
- see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset
controller devices
Example:
prcm: prcm@01f01400 {
compatible = "allwinner,sun6i-a31-prcm";
reg = <0x01f01400 0x200>;
/* Put subdevices here */
ar100: ar100_clk {
compatible = "allwinner,sun6i-a31-ar100-clk";
#clock-cells = <0>;
clocks = <&osc32k>, <&osc24M>, <&pll6>, <&pll6>;
};
ahb0: ahb0_clk {
compatible = "fixed-factor-clock";
#clock-cells = <0>;
clock-div = <1>;
clock-mult = <1>;
clocks = <&ar100_div>;
clock-output-names = "ahb0";
};
apb0: apb0_clk {
compatible = "allwinner,sun6i-a31-apb0-clk";
#clock-cells = <0>;
clocks = <&ahb0>;
clock-output-names = "apb0";
};
apb0_gates: apb0_gates_clk {
compatible = "allwinner,sun6i-a31-apb0-gates-clk";
#clock-cells = <1>;
clocks = <&apb0>;
clock-output-names = "apb0_pio", "apb0_ir",
"apb0_timer01", "apb0_p2wi",
"apb0_uart", "apb0_1wire",
"apb0_i2c";
};
apb0_rst: apb0_rst {
compatible = "allwinner,sun6i-a31-clock-reset";
#reset-cells = <1>;
};
};
