[PATCH v2 1/3] ASoC: qcom: audioreach: Commonize setting channel mappings

[PATCH v2 1/3] ASoC: qcom: audioreach: Commonize setting channel mappings

[Krzysztof Kozlowski]

Move code assigning channel mapping values to a common helper function.
This simplifies three out of four cases, with the last case using
incompatible type (uint16_t array instead of uint8_t array).

[PATCH v2 2/3] ASoC: qcom: audioreach: drop duplicate channel defines

[Krzysztof Kozlowski]

q6apm.h header already defines channel mapping values, so drop
duplicated devices from audioreach.h.

[PATCH v2 3/3] ASoC: qcom: audioreach: Add 4 channel support

[Krzysztof Kozlowski]

Add support four channel streams.  Map channel 3 and 4 to left/right
surround ("quad(side)" from ffmpeg standard channel list) to match what
is in qdsp6/q6dsp-common.c driver.

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
