[alsa-devel] [PATCH v2 1/2] ASoC: sun4i-i2s: Revert "ASoC: sun4i-i2s: Remove duplicated quirks structure"
From: Maxime Ripard maxime.ripard@bootlin.com
This reverts commit 3e9acd7ac6933cdc20c441bbf9a38ed9e42e1490.
It turns out that while one I2S controller is described in the A83t datasheet, the driver supports another, undocumented, one that has been inherited from the older SoCs, while the documented one uses the new design.

The last set of reworks included some fixes to change the A83t behaviour and "fix" it.
It turns out that the controller described in the datasheet and the one supported here are not the same, yet the A83t has the two of them, and the one supported in the driver wasn't the one described in the datasheet.
Fix this by reintroducing the proper quirks.

The patch
ASoC: sun4i: Revert A83t description
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

This patch got applied as
455b1d42e82c ("ASoC: sunxi: Revert initial A83t support")
The new subject is very confusing. If anything it should read
ASoC: sun4i-i2s: Split H3 and later SoC support from A83T support
