has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
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: Maxime Ripard maxime.ripard@bootlin.com Date: Mon, 19 Aug 2019 21:25:19 +0200 Subject: [PATCH] ASoC: sun4i-i2s: Fix LRCK and BCLK polarity offsets on newer SoCs
The LRCK and BCLK polarity offsets on newer SoCs has been changed, yet the driver didn't take it into account for all of them.
This was taken into account for the H3, but not the A83t. This was handled using a reg_field for the H3.
However, the value in that field will not be the same, so reg_field is not adapted in that case. Let's change for proper calls with the regular values.
