The patch

   ASoC: sun4i-i2s: Fix LRCK and BCLK polarity offsets on newer SoCs

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

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.
