Allwinner Clock Control Unit Binding
|
||||
------------------------------------
|
||||
|
||||
Required properties :
|
||||
- compatible: must contain one of the following compatibles:
|
||||
- "allwinner,sun4i-a10-ccu"
|
||||
- "allwinner,sun5i-a10s-ccu"
|
||||
- "allwinner,sun5i-a13-ccu"
|
||||
- "allwinner,sun6i-a31-ccu"
|
||||
- "allwinner,sun7i-a20-ccu"
|
||||

|
||||
- "allwinner,sun8i-a33-ccu"
|
||||
- "allwinner,sun8i-a83t-ccu"
|
||||
- "allwinner,sun8i-a83t-r-ccu"
|
||||
- "allwinner,sun8i-h3-ccu"
|
||||
- "allwinner,sun8i-h3-r-ccu"
|
||||
+ - "allwinner,sun8i-r40-ccu"
|
||||
- "allwinner,sun8i-v3s-ccu"
|
||||
- "allwinner,sun9i-a80-ccu"
|
||||
- "allwinner,sun50i-a64-ccu"
|
||||
- "allwinner,sun50i-a64-r-ccu"
|
||||
- "allwinner,sun50i-h5-ccu"
|
||||
- "allwinner,sun50i-h6-ccu"
|
||||
- "allwinner,sun50i-h6-r-ccu"
|
||||
- "allwinner,suniv-f1c100s-ccu"
|
||||
- "nextthing,gr8-ccu"
|
||||
|
||||
- reg: Must contain the registers base address and length
|
||||
- clocks: phandle to the oscillators feeding the CCU. Two are needed:
|
||||
- "hosc": the high frequency oscillator (usually at 24MHz)
|
||||
- "losc": the low frequency oscillator (usually at 32kHz)
|
||||
On the A83T, this is the internal 16MHz oscillator divided by 512
|
||||
- clock-names: Must contain the clock names described just above
|
||||
- #clock-cells : must contain 1
|
||||
- #reset-cells : must contain 1
|
||||
|
||||
For the main CCU on H6, one more clock is needed:
|
||||
- "iosc": the SoC's internal frequency oscillator
|
||||
|
||||
For the PRCM CCUs on A83T/H3/A64/H6, 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:
|
||||
ccu: clock@1c20000 {
|
||||
compatible = "allwinner,sun8i-h3-ccu";
|
||||
reg = <0x01c20000 0x400>;
|
||||
clocks = <&osc24M>, <&osc32k>;
|
||||
clock-names = "hosc", "losc";
|
||||
#clock-cells = <1>;
|
||||
#reset-cells = <1>;
|
||||
};
|
||||
|
||||
Example for PRCM CCU:
|
||||
r_ccu: clock@1f01400 {
|
||||
compatible = "allwinner,sun50i-a64-r-ccu";
|
||||
reg = <0x01f01400 0x100>;
|
||||
clocks = <&osc24M>, <&osc32k>, <&iosc>, <&ccu CLK_PLL_PERIPH0>;
|
||||
clock-names = "hosc", "losc", "iosc", "pll-periph";
|
||||
#clock-cells = <1>;
|
||||
#reset-cells = <1>;
