Subject: [PATCH 1/3] dt-bindings: clocks: Convert Allwinner DE2 clocks to a schema
Date: Mon, 9 Dec 2019 10:35:56 +0100 [thread overview]
Message-ID: <20191209093558.50940-1-maxime@cerno.tech> (raw)
The newer Allwinner SoCs have a DE2 clocks controller that is supported in
Linux, with a matching Device Tree binding.
Now that we have the DT validation in place, let's convert the device tree
bindings for that controller over to a YAML schemas.

-Allwinner Display Engine 2.0/3.0 Clock Control Binding
-------------------------------------------------------
-
-Required properties :
-- compatible: must contain one of the following compatibles:
- - "allwinner,sun8i-a83t-de2-clk"
- - "allwinner,sun8i-h3-de2-clk"
- - "allwinner,sun8i-v3s-de2-clk"
- - "allwinner,sun50i-a64-de2-clk"
- - "allwinner,sun50i-h5-de2-clk"
- - "allwinner,sun50i-h6-de3-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 (on A83T it's the DE PLL)
- - "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,sun8i-h3-de2-clk";
- reg = <0x01000000 0x100000>;
- clocks = <&ccu CLK_BUS_DE>,
- <&ccu CLK_DE>;
- clock-names = "bus",
- "mod";
- resets = <&ccu RST_BUS_DE>;
- #clock-cells = <1>;
- #reset-cells = <1>;
-};
