ASoC: meson: aiu: introduce a struct for platform specific information

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

Introduce a struct aiu_platform_data to make the driver aware of platform specific information. Convert the existing check for the internal stereo audio codec (only available on GXL) to this new struct. Support for the 32-bit SoCs will need this as well because the AIU_CLK_CTRL_MORE register doesn't have the I2S divider bits (and we need to use the I2S divider from AIU_CLK_CTRL instead).
