25 | - reg: Must contain the registers base address and length | |
26 | - clocks: phandle to the oscillators feeding the CCU. Two are needed: | |
27 | - "hosc": the high frequency oscillator (usually at 24MHz) | |
28 | - "losc": the low frequency oscillator (usually at 32kHz) | |
11ad470c | 29 | On the A83T, this is the internal 16MHz oscillator divided by 512 |
c0692d68 MR |
30 | - clock-names: Must contain the clock names described just above |
31 | - #clock-cells : must contain 1 | |
32 | - #reset-cells : must contain 1 | |

0d28276b | 34 | For the PRCM CCUs on A83T/H3/A64, two more clocks are needed: |
a91afc97 | 35 | - "pll-periph": the SoC's peripheral PLL from the main CCU |
d4879bda IZ |
36 | - "iosc": the SoC's internal frequency oscillator |

38 | Example for generic CCU: | |
c0692d68 MR |
39 | ccu: clock@01c20000 { |
40 | compatible = "allwinner,sun8i-h3-ccu"; | |
41 | reg = <0x01c20000 0x400>; | |
42 | clocks = <&osc24M>, <&osc32k>; | |
43 | clock-names = "hosc", "losc"; | |
44 | #clock-cells = <1>; | |
45 | #reset-cells = <1>; | |
46 | }; | |
d4879bda IZ |
47 | |
48 | Example for PRCM CCU: | |
49 | r_ccu: clock@01f01400 { | |
50 | compatible = "allwinner,sun50i-a64-r-ccu"; | |
51 | reg = <0x01f01400 0x100>; | |
a91afc97 CYT |
52 | clocks = <&osc24M>, <&osc32k>, <&iosc>, <&ccu CLK_PLL_PERIPH0>; |
53 | clock-names = "hosc", "losc", "iosc", "pll-periph"; | |
d4879bda IZ |
54 | #clock-cells = <1>; |
55 | #reset-cells = <1>; | |
56 | }; |
