[alsa-devel] Applied "ASoC: Intel: common: add table for HDA-based platforms" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: common: add table for HDA-based platforms

has been applied to the asoc tree at

   https://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: common: add table for HDA-based platforms

Expose a table containing machine driver information for HDAudio-based
platforms handled by ASoC on Intel hardware.

We only set constant values that are valid across multiple
platforms. The firmware name used by the DSP will be set dynamically
for each platform.

The table is made of a single entry for now, if we need more
complicated set-up where HDAudio is mixed with ACPI-enumerated devices
(I2C, SoundWire) then we'd expect the differentiation to be handled
through information provided by the BIOS (as done for KBL
Chromebooks).
