Add the common parts in H3/H5 DTSI, and add the compatible string in H3 DTSI. The compatible string of H5 DE2 CCU will be added in a separated patch. Signed-off-by: Icenowy Zheng --- Changes in v2: - Use H3 DE2 CCU compatible as it's discovered that H3 and A83T DE2 CCU are not equal. arch/arm/boot/dts/sun8i-h3.dtsi | 4 ++++ arch/arm/boot/dts/sunxi-h3-h5.dtsi | 14 ++++++++++++++ 2 files changed, 18 insertions(+) diff --git a/arch/arm/boot/dts/sun8i-h3.dtsi b/arch/arm/boot/dts/sun8i-h3.dtsi index b36f9f423c39..8495deecedad 100644 --- a/arch/arm/boot/dts/sun8i-h3.dtsi +++ b/arch/arm/boot/dts/sun8i-h3.dtsi @@ -85,6 +85,10 @@ compatible = "allwinner,sun8i-h3-ccu"; }; +&display_clocks { + compatible = "allwinner,sun8i-h3-de2-clk"; +}; + &mmc0 { compatible = "allwinner,sun7i-a20-mmc"; clocks = <&ccu CLK_BUS_MMC0>, diff --git a/arch/arm/boot/dts/sunxi-h3-h5.dtsi b/arch/arm/boot/dts/sunxi-h3-h5.dtsi index d7a71e726a9f..367319d22116 100644 --- a/arch/arm/boot/dts/sunxi-h3-h5.dtsi +++ b/arch/arm/boot/dts/sunxi-h3-h5.dtsi @@ -40,9 +40,11 @@ * OTHER DEALINGS IN THE SOFTWARE. */ +#include #include #include #include +#include #include #include @@ -85,6 +87,18 @@ #size-cells = <1>; ranges; + display_clocks: clock@1000000 { + /* compatible is in per SoC .dtsi file */ + reg = <0x01000000 0x100000>; + clocks = <&ccu CLK_DE>, + <&ccu CLK_BUS_DE>; + clock-names = "mod", + "bus"; + resets = <&ccu RST_BUS_DE>; + #clock-cells = <1>; + #reset-cells = <1>; + }; + syscon: syscon@1c00000 { compatible = "allwinner,sun8i-h3-system-controller", "syscon"; -- 2.13.6
