+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";

+};

it's better that dt-binding should be put in another patch

Please send a followup patch which just converts the entire header to a C++ one so it looks more intentional - otherwise this looks great so I'll apply it!

The patch

ASoC: add mt6351 codec driver

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark

From: Kai Chieh Chuang kaichieh.chuang@mediatek.com Date: Thu, 26 Apr 2018 10:41:44 +0800 Subject: [PATCH] ASoC: add mt6351 codec driver

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

The patch

ASoC: add mt6351 codec driver

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark

From: Kai Chieh Chuang kaichieh.chuang@mediatek.com Date: Thu, 26 Apr 2018 10:41:44 +0800 Subject: [PATCH] ASoC: add mt6351 codec driver

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