1 | Allwinner Clock Control Unit Binding |
2 | ------------------------------------ | |
3 | ||
4 | Required properties : | |
c6e6c96d CYT |
5 | - compatible: must contain one of the following compatibles: |
6 | - "allwinner,sun6i-a31-ccu" | |
5690879d | 7 | - "allwinner,sun8i-a23-ccu" |
d05c748b | 8 | - "allwinner,sun8i-a33-ccu" |
c0692d68 MR |
9 | - "allwinner,sun8i-h3-ccu" |

11 | - reg: Must contain the registers base address and length | |
12 | - clocks: phandle to the oscillators feeding the CCU. Two are needed: | |
13 | - "hosc": the high frequency oscillator (usually at 24MHz) | |
14 | - "losc": the low frequency oscillator (usually at 32kHz) | |
15 | - clock-names: Must contain the clock names described just above | |
16 | - #clock-cells : must contain 1 | |
17 | - #reset-cells : must contain 1 | |
18 | ||
19 | Example: | |
20 | ccu: clock@01c20000 { | |
21 | compatible = "allwinner,sun8i-h3-ccu"; | |
22 | reg = <0x01c20000 0x400>; | |
23 | clocks = <&osc24M>, <&osc32k>; | |
24 | clock-names = "hosc", "losc"; | |
25 | #clock-cells = <1>; | |
26 | #reset-cells = <1>; | |
27 | }; |
