Subject: [PATCH v3 7/8] dt-bindings: clock: samsung: convert S5Pv210 AudSS to dtschema
Date: Wed, 25 Aug 2021 15:42:50 +0200	[thread overview]
Message-ID: <20210825134251.220098-2-krzysztof.kozlowski@canonical.com> (raw)
In-Reply-To: <20210825134056.219884-6-krzysztof.kozlowski@canonical.com>

Convert Samsung S5Pv210 Audio SubSystem clock controller bindings to DT
schema format using json-schema.

Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@canonical.com>
Reviewed-by: Sam Protsenko <semen.protsenko@linaro.org>

-* Samsung Audio Subsystem Clock Controller
-
-The Samsung Audio Subsystem clock controller generates and supplies clocks
-to Audio Subsystem block available in the S5PV210 and compatible SoCs.
-
-Required Properties:
-
-- compatible: should be "samsung,s5pv210-audss-clock".
-- reg: physical base address and length of the controller's register set.
-
-- #clock-cells: should be 1.
-
-- clocks:
-  - hclk: AHB bus clock of the Audio Subsystem.
-  - xxti: Optional fixed rate PLL reference clock, parent of mout_audss. If
-    not specified (i.e. xusbxti is used for PLL reference), it is fixed to
-    a clock named "xxti".
-  - fout_epll: Input PLL to the AudioSS block, parent of mout_audss.
-  - iiscdclk0: Optional external i2s clock, parent of mout_i2s. If not
-    specified, it is fixed to a clock named "iiscdclk0".
-  - sclk_audio0: Audio bus clock, parent of mout_i2s.
-
-- clock-names: Aliases for the above clocks. They should be "hclk",
-  "xxti", "fout_epll", "iiscdclk0", and "sclk_audio0" respectively.
-
-All available clocks are defined as preprocessor macros in
-dt-bindings/clock/s5pv210-audss-clk.h header and can be used in device
-tree sources.
-
-Example: Clock controller node.
-
-	clk_audss: clock-controller@c0900000 {
-		compatible = "samsung,s5pv210-audss-clock";
-		reg = <0xc0900000 0x1000>;
-		#clock-cells = <1>;
-		clock-names = "hclk", "xxti",
-				"fout_epll", "sclk_audio0";
-		clocks = <&clocks DOUT_HCLKP>, <&xxti>,
-				<&clocks FOUT_EPLL>, <&clocks SCLK_AUDIO0>;
-	};
-
-Example: I2S controller node that consumes the clock generated by the clock
-	 controller. Refer to the standard clock bindings for information
-         about 'clocks' and 'clock-names' property.
-
-	i2s0: i2s@3830000 {
-		/* ... */
-		clock-names = "iis", "i2s_opclk0",
-				"i2s_opclk1";
-		clocks = <&clk_audss CLK_I2S>, <&clk_audss CLK_I2S>,
-				<&clk_audss CLK_DOUT_AUD_BUS>;
-		/* ... */
-	};
