The patch ASoC: mediatek: rework clock functions for MT2701
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 d8d99d8ed658a705909b07ba21b643c53851d70c Mon Sep 17 00:00:00 2001 From: Ryder Lee <ryder....@mediatek.com> Date: Tue, 2 Jan 2018 19:47:19 +0800 Subject: [PATCH] ASoC: mediatek: rework clock functions for MT2701 Reworks clock part to make it more reasonable. The current changes are: - Replace regmap operations by CCF APIs. Doing so, we just need to handle the element clocks and can also get accurate information via CCF. - Rename clocks to make them more generic so that the future revisions of the IP can adapt gracefully. - Regroup 'aud_clks[]' by usage - the basic needs and I2S parts: The new code just keep the common clocks in array and let SoC self decide I2S numbers - If future chips have different sets of channels we will add a little more abstract here. Moreover, this patch moves I2S clocks to the struct mt2701_i2s_data so that we can easily manage them when calls .prepare() and .shutdown().
