[alsa-devel] [PATCH] ASoC: rcar: skip disabled-SSI nodes
From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
The current device tree representation of the R-Car SSI assumes that they are numbered consecutively, starting from 0. Alas, this is not the case with the R8A77995 (D3) SoC which SSI1/SSI2 aren't present. In order to keep the existing device trees working, I'm suggesting to use a disabled node for SSI0/SSI1. Teach the SSI probe to just skip disabled nodes.

The patch
ASoC: rcar: skip disabled-SSI nodes
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, Mark
