[PATCH for-next v2 1/2] ASoC: tas2770: Fix reset gpio property name
Fix the reset property name when allocating the GPIO descriptor. The gpiod_get_optional appends either the -gpio or -gpios suffix to the name.

Convert the tas2770 binding to yaml format. Add in the reset-gpio to the binding as it is in the code but not documented in the binding.

Thanks!
[1/2] ASoC: tas2770: Fix reset gpio property name commit: 58b868f51d6e38146e44cb09fcd92b5fc35d83bc [2/2] dt-bindings: tas2770: Convert tas2770 binding to yaml (no commit info)
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
