PATCH 1/2 ASoC: tlv320aic32x4: Add support for tlv320aic32x6

Add support for the tlv320aic32x6 family of devices. These devices share the same register set as the tlv320aic32x4 and this driver can be re-used.

TLV320aic32x6 data sheets are here:
tlv320aic3256 - http://www.ti.com/lit/gpn/tlv320aic3256

PATCH 2/2 ASoC: tlv320aic32x4: Add gpio configuration to the codec

Add the ability to configure the MFP1->MFP5 registers as GPIOs. In addition adding ALSA controls to get and set the GPIO state.

Per the data sheet each MFP can be configured as a GPIO input only, output only or either an input or output.

Applied "ASoC: tlv320aic32x4: Add gpio configuration to the codec" to the asoc tree

The patch

ASoC: tlv320aic32x4: Add gpio configuration to the codec

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,
