When resetting the block, the reset line is being driven low and then
high, which means that the line in DTS should be annotated as "active
low". It will become important when wcd9335 driver will be converted
to gpiod API that respects declared line polarities.

[2/6] ASoC: dt-bindings: wcd9335: fix reset line polarity in example commit: 34cb111f8a7b98b5fec809dd194003bca20ef1b2 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
