1* Allwinner PRCM (Power/Reset/Clock Management) Multi-Functional Device 2 3PRCM is an MFD device exposing several Power Management related devices 4(like clks and reset controllers). 5 6Required properties: 7 - compatible: "allwinner,sun6i-a31-prcm" or "allwinner,sun8i-a23-prcm" 8 - reg: The PRCM registers range 9 10The prcm node may contain several subdevices definitions: 11 - see Documentation/devicetree/clk/sunxi.txt for clock devices 12 - see Documentation/devicetree/reset/allwinner,sunxi-clock-reset.txt for reset 13 controller devices 14 15 16Example: 17 18 prcm: prcm@01f01400 { 19 compatible = "allwinner,sun6i-a31-prcm"; 20 reg = <0x01f01400 0x200>; 21 22 /* Put subdevices here */ 23 ar100: ar100_clk { 24 compatible = "allwinner,sun6i-a31-ar100-clk"; 25 #clock-cells = <0>; 26 clocks = <&osc32k>, <&osc24M>, <&pll6>, <&pll6>; 27 }; 28 29 ahb0: ahb0_clk { 30 compatible = "fixed-factor-clock"; 31 #clock-cells = <0>; 32 clock-div = <1>; 33 clock-mult = <1>; 34 clocks = <&ar100_div>; 35 clock-output-names = "ahb0"; 36 }; 37 38 apb0: apb0_clk { 39 compatible = "allwinner,sun6i-a31-apb0-clk"; 40 #clock-cells = <0>; 41 clocks = <&ahb0>; 42 clock-output-names = "apb0"; 43 }; 44 45 apb0_gates: apb0_gates_clk { 46 compatible = "allwinner,sun6i-a31-apb0-gates-clk"; 47 #clock-cells = <1>; 48 clocks = <&apb0>; 49 clock-output-names = "apb0_pio", "apb0_ir", 50 "apb0_timer01", "apb0_p2wi", 51 "apb0_uart", "apb0_1wire", 52 "apb0_i2c"; 53 }; 54 55 apb0_rst: apb0_rst { 56 compatible = "allwinner,sun6i-a31-clock-reset"; 57 #reset-cells = <1>; 58 }; 59 }; 60
