Hello all,

This series has the end goal of adding headphone detection to the tlv320aic31xx driver. The first few patches are mostly cleanups. Then a couple bug fixes I noticed. Followed by adding interrupt handling and finally headphone detection.

Still not sure if the IRQ patch is correct, I think we have no good way to share this IRQ line, so leaving it the way it is for now.

Thanks, Andrew

Changes from v2: - Rebased on -next - Added delta patch for GPIO header fix - Split platform data remove into fwnode and pdata removal - Rework reset patch to print error code - Use snd_soc_codec_set_jack to set jack

Changes from v1: - Splitup the cleanup patch a bit more - Move the GPIO1 register fix patch before header cleanup so it can be taken back into stable - Added Acked-by - New patch dealing with regulator notifications - Various small touchups - Rebased on v4.15-rc1

The patch

ASoC: tlv320aic31xx: Fix GPIO header includes

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

New subject: [alsa-devel] [PATCH v3 05/10] ASoC: tlv320aic31xx: Remove regulator notification handling

A regulator being forcefully disabled is a catastrophic event that should never happen to most devices, especially not sound CODECs. In addition, our handler sets the reset line but never disables it as no one is listening for an enable event, this is certainly broken and was mosy likely just copied from other CODECs, lets just remove this code.

Add a reset function that toggles the reset line if available or uses the software reset command otherwise. Use this in power up to ensure the registers are in a sane state. This is useful when the driver module is reloaded, or after Kexec, warm-reboots, etc..

New subject: [alsa-devel] [PATCH v3 07/10] ASoC: tlv320aic31xx: Add short circuit detection support

These devices support detecting and reporting short circuits across the output stages. Add support for reporting these issue. Do this by registering an interrupt if available and enabling this error to trigger that interrupt in the device.

New subject: [alsa-devel] [PATCH v3 08/10] ASoC: tlv320aic31xx: Add overflow detection support

Similar to short circuit detection, when the ADC/DAC is saturated and overflows poor audio quality can result and should be reported to the user. This device support Automatic Dynamic Range Compression (DRC) to reduce this but it is not enabled currently in this driver.

New subject: [alsa-devel] [PATCH v3 09/10] ASoC: tlv320aic31xx: Add headphone/headset detection

This device can detect the insertion/removal of headphones and headsets. Enable reporting this status by enabling this interrupt and forwarding this to upper-layers if a jack has been defined.

This jack definition and the resulting operation from a jack detection event must currently be defined by sound card platform code until CODEC outputs to jack mappings can be defined generically.
