[PATCH v5 0/3] ASoC: sun4i-codec: Distinguish sun4i from sun7i

[PATCH v5 0/3] ASoC: sun4i-codec: Distinguish sun4i from sun7i

[Danny Milosavljevic]

ASoC: sun4i-codec: Introduce mechanism to detect sun7i and provide a
different regmap different compared to sun4i Allwinner A10.
 
The controls will be extended in a forthcoming patch - it is necessary
to distinguish between sun4i and sun7i controls because they have different
registers.
 
Renamed SUN4I_CODEC_AC_SYS_VERI to SUN7I_CODEC_AC_DAC_CAL and renamed
SUN4I_CODEC_AC_MIC_PHONE_CAL to SUN7I_CODEC_AC_MIC_PHONE_CAL because these
are actually not present on Allwinner A10.

Handle quirks by regmap config and codec and select the correct quirks
automatically.  

Danny Milosavljevic (3):
  ASoC: sun4i-codec: rename "sun4i_codec_widgets" to
    "sun4i_codec_controls" for consistency with the struct field name.
  ASoC: rename "SUN4I_CODEC_SYS_VERI" to "SUN7I_CODEC_AC_DAC_CAL";
    rename "SUN4I_CODEC_AC_MIC_PHONE_CAL" to
    "SUN7I_CODEC_AC_MIC_PHONE_CAL".
  ASoC: sun4i-codec: Add custom regmap configs for the A10 and A20
    variants.

Your commit log still has the flaws your other patches had in the
previous version.

[PATCH v5 2/3] ASoC: sun4i-codec: Rename some sun7i-only registers

[Danny Milosavljevic]

Some of the registers defined in the driver are only usable on the
A20. Rename these registers.

Usually, you would set the history of changes from one version to the
other here.

[PATCH v5 3/3] ASoC: sun4i-codec: Add custom regmap configs

[Danny Milosavljevic]

The A20 has a few extra registers that the A10 doesn't have.
Therefore, use different regmaps for A10 as compared to A20.

Applied "ASoC: sun4i-codec: Add custom regmap configs" to the asoc tree

[Mark Brown]

The patch

   ASoC: sun4i-codec: Add custom regmap configs

has been applied to the asoc tree at

   git://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,
