[alsa-devel] Applied "ASoC: Intel: boards: use devm_clk_get() unconditionally" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: boards: use devm_clk_get() unconditionally

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

Subject: [PATCH] ASoC: Intel: boards: use devm_clk_get() unconditionally

The clock framework was only used in Baytrail, on Cherrytrail
the firmware takes care of the MCLK/plt_clk_3.

With the fix in 'commit d31fd43c0f9a
("clk: x86: Do not gate clocks enabled by the firmware")'

the firmware-managed clocks are not impacted by enable/disable
requests make at the driver level, and the rates are identical.

Remove all checks for Baytrail and use devm_clk_get()
unconditionally. Tested on Asus T100HA (CHT) and Asus T100TAF (BYT)

Note that the RT5640 and RT5645 machine drivers need to keep some
checks for Valleyview to check for Baytrail-CR.
