Signed-off-by: Icenowy Zheng Acked-by: Rob Herring --- Changes in v5: - Moved dt-binding headers here. - Changed dt-binding headers' license header to SPDX license. Changes in v4: - Dropped the leading 0 in clock at 1000000 . Changes in v3: - Fill the address space length of DE2 CCU to 0x100000, just reach the start of mixer0. .../devicetree/bindings/clock/sun8i-de2.txt | 31 ++++++++++++++++++++++ include/dt-bindings/clock/sun8i-de2.h | 18 +++++++++++++ include/dt-bindings/reset/sun8i-de2.h | 14 ++++++++++ 3 files changed, 63 insertions(+) create mode 100644 Documentation/devicetree/bindings/clock/sun8i-de2.txt create mode 100644 include/dt-bindings/clock/sun8i-de2.h create mode 100644 include/dt-bindings/reset/sun8i-de2.h diff --git a/Documentation/devicetree/bindings/clock/sun8i-de2.txt b/Documentation/devicetree/bindings/clock/sun8i-de2.txt new file mode 100644 index 000000000000..15a60bd7dcf3 --- /dev/null +++ b/Documentation/devicetree/bindings/clock/sun8i-de2.txt @@ -0,0 +1,31 @@ +Allwinner Display Engine 2.0 Clock Control Binding +-------------------------------------------------- + +Required properties : +- compatible: must contain one of the following compatibles: + - "allwinner,sun8i-a83t-de2-clk" + - "allwinner,sun50i-a64-de2-clk" + - "allwinner,sun50i-h5-de2-clk" + +- reg: Must contain the registers base address and length +- clocks: phandle to the clocks feeding the display engine subsystem. + Three are needed: + - "mod": the display engine module clock + - "bus": the bus clock for the whole display engine subsystem +- clock-names: Must contain the clock names described just above +- resets: phandle to the reset control for the display engine subsystem. +- #clock-cells : must contain 1 +- #reset-cells : must contain 1 + +Example: +de2_clocks: clock@1000000 { + compatible = "allwinner,sun50i-a64-de2-clk"; + 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>; +}; diff --git a/include/dt-bindings/clock/sun8i-de2.h b/include/dt-bindings/clock/sun8i-de2.h new file mode 100644 index 000000000000..3bed63b524aa --- /dev/null +++ b/include/dt-bindings/clock/sun8i-de2.h @@ -0,0 +1,18 @@ +/* + * Copyright (C) 2016 Icenowy Zheng + * + * SPDX-License-Identifier: (GPL-2.0+ OR MIT) + */ + +#ifndef _DT_BINDINGS_CLOCK_SUN8I_DE2_H_ +#define _DT_BINDINGS_CLOCK_SUN8I_DE2_H_ + +#define CLK_BUS_MIXER0 0 +#define CLK_BUS_MIXER1 1 +#define CLK_BUS_WB 2 + +#define CLK_MIXER0 6 +#define CLK_MIXER1 7 +#define CLK_WB 8 + +#endif /* _DT_BINDINGS_CLOCK_SUN8I_DE2_H_ */ diff --git a/include/dt-bindings/reset/sun8i-de2.h b/include/dt-bindings/reset/sun8i-de2.h new file mode 100644 index 000000000000..9526017432f0 --- /dev/null +++ b/include/dt-bindings/reset/sun8i-de2.h @@ -0,0 +1,14 @@ +/* + * Copyright (C) 2016 Icenowy Zheng + * + * SPDX-License-Identifier: (GPL-2.0+ OR MIT) + */ + +#ifndef _DT_BINDINGS_RESET_SUN8I_DE2_H_ +#define _DT_BINDINGS_RESET_SUN8I_DE2_H_ + +#define RST_MIXER0 0 +#define RST_MIXER1 1 +#define RST_WB 2 + +#endif /* _DT_BINDINGS_RESET_SUN8I_DE2_H_ */
