Subject: [PATCH v2 0/3] ASoC: Codecs: Add TDA7802 codec

Hi,
This patch series adds a driver for the ST TDA7802 amplifier.

Thank you Mark Brown, Charles Keepax, Cezary Rojewski and Kirill
Marinushkin for your time and useful feedback (on IRC too). Sorry for
taking so long in getting back to you, there were quite a lot of
changes!

Please let me know if there's anything else which needs changing.

Many thanks,
Thomas

+ST TDA7802 audio processor
+
+This device supports I2C only.
+
+Required properties:
+
+- compatible : "st,tda7802"
+- reg : the I2C address of the device
+- enable-supply : a regulator spec for the PLLen pin
+
+Optional properties:
+
+- st,gain-ch13 : gain for channels 1 and 3 (range: 1-4)
+- st,gain-ch24 : gain for channels 2 and 3 (range: 1-4)
+- st,diagnostic-mode-ch13 : diagnotic mode for channels 1 and 3
+ values: "Speaker" (default), "Booster"
+- st,diagnostic-mode-ch24 : diagnotic mode for channels 2 and 4
+ values: "Speaker" (default), "Booster"
+
+Example:
+
+amp: tda7802@6c {
+ compatible = "st,tda7802";
+ reg = <0x6c>;
+ enable-supply = <&amp_enable_reg>;
