Each platform has different supported rates and
formats, so add soc specific data for each platform.
This soc specific data is attached with compatible string.

[1/1] ASoC: fsl_rpmsg: add soc specific data structure
commit: b7bbbf01362720a8066e3f6d880cae6d63fc92f6
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
