[RESENT PATCH v6 0/8] ASoC: rockchip: Parse dai links from dts

[RESENT PATCH v6 0/8] ASoC: rockchip: Parse dai links from dts

[Jeffy Chen]

Currently we are using a fixed list of dai links in the driver.
This serial of patches would let the driver parse dai links from
dts, so that we can make some of them optional for future boards.

Tested on my chromebook bob(with cros 4.4 kernel), it still works
after disabled rt5514 codecs in the dts.


Changes in v6:
Add dmic wakeup delay(not used for now).

Changes in v5:
Keep the dmic-delay property, but correct it with the name in
dt-binding.
        -- Suggested-by Mark Brown <broonie@kernel.org>

Changes in v3:
Use compatible to match audio codecs
        -- Suggested-by Matthias Kaehlcke <mka@chromium.org>

Changes in v2:
Let rockchip,codec-names be a required property, because we plan to
add more supported codecs to the fixed dai link list in the driver.

[RESENT PATCH v6 1/8] ASoC: rockchip: Correct 'dmic-delay' property name

[Jeffy Chen]

The 'dmic-delay' property name is different with the dt-binding.

So correct it with 'dmic-wakeup-delay-ms'.

Applied "ASoC: rockchip: Update description of rockchip, codec" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip: Update description of rockchip, codec

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,
Mark
