[alsa-devel] [PATCH v2 0/3] Fix capture devices functionality on TM2
Hello,
This patchset makes capture functionality working on TM2.
Capture devices can't be detected because I2S doesn't have appropriate dai name. Therefore, TM2 will select unexpected cpu dai which is named "i2s-samsung-sec" that doesn't have a capture functionality.
In samsung I2S driver, it tries to register two components without specific name. The driver finally has components having same name: dai name as well. As a result, dai_link doesn't have enough information to select cpu_dai properly.
Changes in v2: - defined SAMSUNG_I2S_DAI_* in i2s.h and removed duplicated code - modified commit message about invalid parameter that Krzystof mentioned - rebased code because of conflicts in i2s.c
Jaechul Lee (3): ASoC: samsung: i2s: Use specific name for i2s dais ASoC: samsung: Use 'samsung-i2s' cpu_dai for dai_links ASoC: samsung: Fix invalid argument when devm_gpiod_get is called

Add specific dais name when components are registered. Component and dai name will follow their parent dev name, if the name isn't described. In case of this driver, each dais will have same name like '11440000.i2s0' by fmt_single_name function.
The problem having same name is that TM2 machine driver can't detect capture devices correctly. Machine driver doesn't know which one is proper to use for cpu dai. The driver just selects to use 'samsung-i2c-sec' that doesn't have capture functionality because the component of samsung-i2s-sec is located in the first of the component_list.
I add dai name like 'samsung-i2s', 'samsung-i2s-sec' for each dais. The reason why adding dai id to 1 is that it doesn't allow to use particular dai name in case of when I use 0 for dai id.

The patch
ASoC: samsung: i2s: Use specific name for i2s dais
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

Muted stream comes up when I try recording some sounds on TM2. mic-bias gpiod state can't be changed because the gpiod is created with the invalid parameter. The gpio should be set GPIOD_OUT_HIGH.
