The patch ASoC: wsa881x: mark read_only_wordlength flag 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 0f2a3b02274c02eb97697c4d89c019d1d21ac225 Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla <srinivas.kandagatla@xxxxxxxxxx> Date: Tue, 14 Apr 2020 12:03:47 +0100 Subject: [PATCH] ASoC: wsa881x: mark read_only_wordlength flag WSA881x works in PDM mode so the wordlength is fixed, which also makes the only field "WordLength" in DPN_BlockCtrl1 register a read-only. Writing to this register will throw up errors with Qualcomm Controller. So use ro_blockctrl1_reg flag to mark this field as read-only so that core will not write to this register.
