-This device supports I2C only.
-
-Required properties:
-
- - compatible : "wlf,wm8903"
-
- - reg : the I2C address of the device.
-
- - gpio-controller : Indicates this device is a GPIO controller.
-
- - #gpio-cells : Should be two. The first cell is the pin number and the
- second cell is used to specify optional parameters (currently unused).
-
-Optional properties:
-
- - interrupts : The interrupt line the codec is connected to.
-
- - micdet-cfg : Default register value for R6 (Mic Bias). If absent, the
- default is 0.
-
- - micdet-delay : The debounce delay for microphone detection in mS. If
- absent, the default is 100.
-
- - gpio-cfg : A list of GPIO configuration register values. The list must
- be 5 entries long. If absent, no configuration of these registers is
- performed. If any entry has the value 0xffffffff, that GPIO's
- configuration will not be modified.

Please submit patches using subject lines reflecting the style for the
subsystem, this makes it easier for people to identify relevant patches.
Look at what existing commits in the area you're changing are doing and
make sure your subject lines visually resemble what they're doing.
There's no need to resubmit to fix this alone.

[1/1] dt-bindings: sound: wlf,wm8903: Convert txt bindings to yaml
commit: 5ecc573d0c542c0f95497ba4586a6226814e4e18
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
