The patch ASoC: soc-core: do pinctrl_pm_select_xxx() as component has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6 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 76c39e867cba338d8982f6372b2c4e3189f6439b Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Fri, 10 Jan 2020 11:36:13 +0900 Subject: [PATCH] ASoC: soc-core: do pinctrl_pm_select_xxx() as component ALSA SoC need to care pinctrl_pm_select_xxx(). It is called at soc-core and soc-pcm. soc-pcm is controlling it for activate DAI. soc-core is controlling it for whole system (= suspend/resume/probe/poweroff). If we focus to soc-core side, it need to care about BIAS level. Then, snd_soc_suspend() only is controlling it by Component base (a). Other functions are DAI base (b). (a) pinctrl_pm_select_xxx(component->dev, xxx); (b) pinctrl_pm_select_xxx(dai->dev, xxx); Because of these unbalance, the code is confusable. Here, dai->dev and component->dev are same pointer. Thus, we can replace it component base. One note here is that it cared DAI (= CPU/Codec) pin before this patch, after this patch, it cares Component (= CPU/Codec/Platform) pin.
