[Kuninori Morimoto]

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

DTC commit df536831d02c ("checks: add graph binding checks")
is checking endpoint bidirectional, and it is upstreamed to linux by

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.

[PATCH 02/10] ASoC: rsnd: rename rsnd_runtime_is_ssi_xxx()

[Kuninori Morimoto]

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

Current rsnd driver has rsnd_runtime_is_ssi_xxx() functions,
but it is not only related to SSI, thus, it is misunderstandable.
This patch renames it.

Subject: [PATCH] ASoC: rsnd: move HDMI information from ssi.c to core.c

Current driver is supporting HDMI output, and its information
are handled under ssi.c. But, it is stream information.
Let's move it from ssi.c to core.c.

[PATCH 05/10] ASoC: rsnd: handle DPCM converted rate/chan under core

[Kuninori Morimoto]

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

converted rate/chan are handled each rated module, but
it will be used other module too.
For examle, converted channel is currently used for CTU,
but, it will be used for TDM Split mode, too.

This patch move/merge SRC/CTU hw_param under core.c
and handles converted rate/chan under rsnd_dai_stream.

Subject: [PATCH] ASoC: rsnd: handle DPCM converted rate/chan under core

converted rate/chan are handled each rated module, but
it will be used other module too.
For examle, converted channel is currently used for CTU,
but, it will be used for TDM Split mode, too.

This patch move/merge SRC/CTU hw_param under core.c
and handles converted rate/chan under rsnd_dai_stream.

[PATCH 07/10] ASoC: rsnd: add SSIU BUSIF support for Document

[Kuninori Morimoto]

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

Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU.
Current driver is assuming it is using BUSIF0 as default.
Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach().
But, TDM split mode also needs other BUSIF to use it.
This patch adds missing SSIU BUSIFx support.

BUSIF is handled by SSIU instead of SSI anymore.
Thus, its settings no longer needed on SSI node on DT.
This patch removes its settings from Document, but driver is still
keeping compatibility. Thus, old DT style is still working.
But, to avoid confusing, it doesn't indicate old compatibility things on
Document. New SoC should have SSIU on DT from this patch.

1) old style DT is still supported (= no rcar_sound,ssiu node on DT)
2) If ssiu is not indicated on playback/capture,
   BUSIF0 will be used as default
	playback = <&ssi3>; /* ssiu30 will be selected */
3) you can select own ssiu
	playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */

   ASoC: rsnd: add SSIU BUSIF support for Document

has been applied to the asoc tree at

   https://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.

Subject: [PATCH] ASoC: rsnd: add SSIU BUSIF support for Document

Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU.
Current driver is assuming it is using BUSIF0 as default.
Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach().
But, TDM split mode also needs other BUSIF to use it.
This patch adds missing SSIU BUSIFx support.

BUSIF is handled by SSIU instead of SSI anymore.
Thus, its settings no longer needed on SSI node on DT.
This patch removes its settings from Document, but driver is still
keeping compatibility. Thus, old DT style is still working.
But, to avoid confusing, it doesn't indicate old compatibility things on
Document. New SoC should have SSIU on DT from this patch.

1) old style DT is still supported (= no rcar_sound,ssiu node on DT)
2) If ssiu is not indicated on playback/capture,
   BUSIF0 will be used as default
	playback = <&ssi3>; /* ssiu30 will be selected */
3) you can select own ssiu
	playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */

[PATCH 08/10] ASoC: rsnd: add SSIU BUSIF support

Subject: [PATCH] ASoC: rsnd: add SSIU BUSIF support

Gen2 has BUSIF0-3, Gen3 has BUSIF0-7 on some SSIU.
Current driver is assuming it is using BUSIF0 as default.
Thus, SSI is attaching SSIU (with BUSIF0) by using rsnd_ssiu_attach().
But, TDM split mode also needs other BUSIF to use it.
This patch adds missing SSIU BUSIFx support.

BUSIF is handled by SSIU instead of SSI anymore.
Thus, its settings no longer needed on SSI node on DT.
This patch removes its settings from Document, but driver is still
keeping compatibility. Thus, old DT style is still working.
But, to avoid confusing, it doesn't indicate old compatibility things on
Document. New SoC should have SSIU on DT from this patch.

1) old style DT is still supported (= no rcar_sound,ssiu node on DT)
2) If ssiu is not indicated on playback/capture,
   BUSIF0 will be used as default
	playback = <&ssi3>; /* ssiu30 will be selected */
3) you can select own ssiu
	playback = <&ssi32 &ssi3>; /* ssiu32 will be selected */
