[PATCH 0/3] ASoC: rsnd: HDMI sound support

[Kuninori Morimoto]

Hi Mark

These supports HDMI sound on Renesas R-Car driver.
These are based on of-graph base sound card.

Kuninori Morimoto (3):
  ASoC: rsnd: add support graph base DT phase 1
  ASoC: rsnd: add support graph base DT phase 2
  ASoC: rsnd: add HDMI output support

[PATCH 1/3] ASoC: rsnd: add support graph base DT phase 1

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

To enable OF-graph base DT on rsnd driver, and to keep compatible
previous normal sound card style, it need to support both
"rcar_sound,dai" and "ports" (or "port") on DT.

This patch modify rsnd_dai_of_node() to parse
"rcar_sound,dai" and "ports" (or "port") as phase 1. It can detect
graph base style, but do nothing at this point.

[PATCH 3/3] ASoC: rsnd: add HDMI output support

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Renesas R-Car Gen3 can output HDMI sound if SSIU/SSI are connected to
R-Car built-in HDMI device (R-Car Gen3 built-in HDMI device will be
controlled by DRM/KMS driver).
If SSIx was connected to HDMI0/1 on DT, SSI driver will detect it
automatically by this patch.
Note is that now Renesas R-Car sound driver is assuming that it is
using OF-graph base simple card for HDMI sound.

Applied "ASoC: rsnd: add HDMI output support" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: add HDMI output support

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
