[PATCH 0/3] ASoC: rsnd: prepare patches for BUSIF support

[Kuninori Morimoto]

Hi Mark

These are prepare/cleanup for for Renesas rsnd driver BUSIF support.
I will post BUSIF support patch soon, but it needs
Jiada Wang <jiada_wang@mentor.com> 's check.
If it was OK, I will focus to TDM split mode.

Kuninori Morimoto (3):
  ASoC: rsnd: move .get_status under rsnd_mod_ops
  ASoC: rsnd: add .get_id/.get_id_sub
  ASoC: rsnd: rsnd_mod_name() handles both name and ID

[PATCH 1/3] ASoC: rsnd: move .get_status under rsnd_mod_ops

[Kuninori Morimoto]

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

Each mod needs to have .get_status, but current driver is handling it
under rsnd_mod, instead of rsnd_mod_ops.
It is not any make sence. This patch moves it to rsnd_mod_ops, and
tidyup its parameter order to align to other callback functions.

[PATCH 2/3] ASoC: rsnd: add .get_id/.get_id_sub

[Kuninori Morimoto]

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

ID for CTU and SSIU are confusable.
1 CTU has 4 sub nodes. This means, CTU0 has CTU01 - CTU03, CTU1 has
CTU10 - CTU13. SSIU is more confusable. Gen2 SSIU has BUSIF0-3, Gen3
SSIU has BUSIF0-7, but not for all SSIU.
In rsnd driver, each mod drivers are assuming rsnd_mod_id() returns
main device ID (In CTU case CTU0-1, SSIU case SSIU0-9), not serial
number.
This patch adds new .id/.id_sub to handling more detail ID.

[PATCH 3/3] ASoC: rsnd: rsnd_mod_name() handles both name and ID

[Kuninori Morimoto]

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

Current rsnd driver is using "%s[%d]" for mod name and ID,
but, this ID portion might confusable.
For example currently, CTU ID is 0 to 7, but using 00 to 13
(= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet.

In the future, we will support BUSIFn, but it will be more complicated
numbering. To avoid future confusable code, this patch modify
rsnd_mod_name() to return understandable name.

To avoid using pointless memory, it uses static char and snprintf,
thus, rsnd_mod_name() user should use it immediately, and shouldn't keep
its pointer.

Applied "ASoC: rsnd: rsnd_mod_name() handles both name and ID" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: rsnd_mod_name() handles both name and ID

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.

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: rsnd: rsnd_mod_name() handles both name and ID

Current rsnd driver is using "%s[%d]" for mod name and ID,
but, this ID portion might confusable.
For example currently, CTU ID is 0 to 7, but using 00 to 13
(= 00, 01, 02, 03, 10, 11, 12, 13) is very best matching to datasheet.

In the future, we will support BUSIFn, but it will be more complicated
numbering. To avoid future confusable code, this patch modify
rsnd_mod_name() to return understandable name.

To avoid using pointless memory, it uses static char and snprintf,
thus, rsnd_mod_name() user should use it immediately, and shouldn't keep
its pointer.

Subject: [PATCH] ASoC: rsnd: add .get_id/.get_id_sub

ID for CTU and SSIU are confusable.
1 CTU has 4 sub nodes. This means, CTU0 has CTU01 - CTU03, CTU1 has
CTU10 - CTU13. SSIU is more confusable. Gen2 SSIU has BUSIF0-3, Gen3
SSIU has BUSIF0-7, but not for all SSIU.
In rsnd driver, each mod drivers are assuming rsnd_mod_id() returns
main device ID (In CTU case CTU0-1, SSIU case SSIU0-9), not serial
number.
This patch adds new .id/.id_sub to handling more detail ID.

Applied "ASoC: rsnd: move .get_status under rsnd_mod_ops" to the asoc tree

[Mark Brown]

The patch

   ASoC: rsnd: move .get_status under rsnd_mod_ops

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.

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: rsnd: move .get_status under rsnd_mod_ops

Each mod needs to have .get_status, but current driver is handling it
under rsnd_mod, instead of rsnd_mod_ops.
It is not any make sence. This patch moves it to rsnd_mod_ops, and
tidyup its parameter order to align to other callback functions.
