Subject: [PATCH v2] dt-bindings: sound: Convert Samsung Exynos Odroid
 XU3/XU4 audio complex to dt-schema
Date:   Thu, 17 Oct 2019 12:05:29 +0200

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Maciej Falkowski <m.falkowski@samsung.com>

Convert Samsung Exynos Odroid XU3/XU4 audio complex with MAX98090 codec
to newer dt-schema format.

'clocks' property is unneeded in the bindings and is left undefined in 'properties'.

'samsung,audio-widgets' and 'samsung,audio-routing' are optional from driver
perspective and they are set as unrequired.

-Samsung Exynos Odroid XU3/XU4 audio complex with MAX98090 codec
-
-Required properties:
-
- - compatible - "hardkernel,odroid-xu3-audio" - for Odroid XU3 board,
-		"hardkernel,odroid-xu4-audio" - for Odroid XU4 board (deprecated),
-		"samsung,odroid-xu3-audio" - for Odroid XU3 board (deprecated),
-		"samsung,odroid-xu4-audio" - for Odroid XU4 board (deprecated)
- - model - the user-visible name of this sound complex
- - clocks - should contain entries matching clock names in the clock-names
-    property
- - samsung,audio-widgets - this property specifies off-codec audio elements
-   like headphones or speakers, for details see widgets.txt
- - samsung,audio-routing - a list of the connections between audio
-   components;  each entry is a pair of strings, the first being the
-   connection's sink, the second being the connection's source;
-   valid names for sources and sinks are the MAX98090's pins (as
-   documented in its binding), and the jacks on the board
-
-   For Odroid X2:
-     "Headphone Jack", "Mic Jack", "DMIC"
-
-   For Odroid U3, XU3:
-     "Headphone Jack", "Speakers"
-
-   For Odroid XU4:
-     no entries
-
-Required sub-nodes:
-
- - 'cpu' subnode with a 'sound-dai' property containing the phandle of the I2S
-    controller
- - 'codec' subnode with a 'sound-dai' property containing list of phandles
-    to the CODEC nodes, first entry must be corresponding to the MAX98090
-    CODEC and the second entry must be the phandle of the HDMI IP block node
-
-Example:
-
-sound {
-	compatible = "hardkernel,odroid-xu3-audio";
-	model = "Odroid-XU3";
-	samsung,audio-routing =
-		"Headphone Jack", "HPL",
-		"Headphone Jack", "HPR",
-		"IN1", "Mic Jack",
-		"Mic Jack", "MICBIAS";
-
-	cpu {
-		sound-dai = <&i2s0 0>;
-	};
-	codec {
-		sound-dai = <&hdmi>, <&max98090>;
-	};
-};
