[PATCH v2 0/4] ASoC: rsrc-card to simple-scu-card

[PATCH v2 0/4] ASoC: rsrc-card to simple-scu-card

[Kuninori Morimoto]

Hi Mark

Thesee are v2 of rsrc-card to simple-scu-card.

rsrc-card was created for DPCM sound card for Renesas,
but we can reuse this driver as more generic purpose.
This driver is supporting Multi CPU and Single Codec DPCM system.

Kuninori Morimoto (4):
  ASoC: rsrc-card: remove board specific compatible
  ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase1
  ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase2
  ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase3

[PATCH v2 1/4] ASoC: rsrc-card: remove board specific compatible

[Kuninori Morimoto]

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

rsrc-card has board specific compatible (= lager/koelsh), but these were
created as 1st prototype, and it is used in my test environment only.
Now normal user can use generic compatible (= renesas,rsrc-card).
Removing these board specific compatible doesn't breake compatibility.
This patch remove these.

rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to

[PATCH v2 3/4] ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase2

[Kuninori Morimoto]

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

rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 2nd step,
this patch adds new compatible "simple-scu-audio-card";

rcar-card used specific property, not "simple-audio-card",
but it should be now. Actually, rsrc-card is upstreamed driver,
but noone is using it on upstream. The user is only local,
and it is only me. Thus, there is no compatible break by this patch.
This patch uses "simple-audio-card" prefix.
And it removes rcar-card specifix compatible too.

[PATCH v2 4/4] ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase3

[Kuninori Morimoto]

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

rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 3rd step,
this patch moves rsrc-card driver to generic folder.

Subject: [PATCH] ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase2

rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 2nd step,
this patch adds new compatible "simple-scu-audio-card";

rcar-card used specific property, not "simple-audio-card",
but it should be now. Actually, rsrc-card is upstreamed driver,
but noone is using it on upstream. The user is only local,
and it is only me. Thus, there is no compatible break by this patch.
This patch uses "simple-audio-card" prefix.
And it removes rcar-card specifix compatible too.

Subject: [PATCH] ASoC: rsrc-card: rename rsrc-card to simple-scu-card phase1

rsrc-card which is using DPCM feature was created for Renesas sound.
But not only Renesas, but many SoC can use this driver, because
it is based on simple-card driver.
To use it as more open driver, rsrc-card will be renamed to
simple-scu-card. In order to easy patch review, as 1st step,
this patch renames "rsrc" function prefix to "asoc_simple".

Applied "ASoC: rsrc-card: remove board specific compatible" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsrc-card: remove board specific compatible

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

Subject: [PATCH] ASoC: rsrc-card: remove board specific compatible

rsrc-card has board specific compatible (= lager/koelsh), but these were
created as 1st prototype, and it is used in my test environment only.
Now normal user can use generic compatible (= renesas,rsrc-card).
Removing these board specific compatible doesn't breake compatibility.
This patch remove these.
