[PATCH v3 1/5] ASoC: add mt6351 codec driver

KaiChieh Chuang
2018-04-25T02:48:48Z

This patch adds the MediaTek MT6351 codec driver.
MT6351 communicate with SoC through MediaTek PMIC wrapper.
MT6351 use MediaTek proprietary audio interface.

+Mediatek MT6351 Audio Codec
+
+The communication between MT6351 and SoC is through Mediatek PMIC wrapper.
+For more detail, please visit Mediatek PMIC wrapper documentation.
+
+Must be a child node of PMIC wrapper.
+
+Required properties:
+
+- compatible : "mediatek,mt6351-sound".
+
+Example:
+
+mt6351_snd {
+ compatible = "mediatek,mt6351-sound";
+};
