[RFT v2 0/5] ASoC: samsung: Minor cleanup for old machines

[Krzysztof Kozlowski]

Hi,


Few patches removing dead code (machines not supported).


Changes since v1:
1. Squash two smdk_wm8580 changes into patch #2.  Now num_dai_links
   is always equal to two, so remove also SEC_PLAYBACK dai_link.
   (suggested by Lars-Peter Clausen).


The second patch ([RFT v2 2/5] ASoC: samsung: smdk_wm8580: Remove old platforms and
drop mach-types usage) requires testing. I hope I understood the code
correctly.

The last ARM patch is independent. I will take it through samsung-soc
tree. I put it here for reference.


Best regards,
Krzysztof

[PATCH v2 1/5] ASoC: samsung: Remove non-existing MACH dependencies

[Krzysztof Kozlowski]

MACH_SMDKC100 was removed in commit b8529ec1c1b0 ("ARM: S5PC100: no more
support S5PC100 SoC"). MACH_SMDKV210 and MACH_SMDKC110 in commit
28c8331d386 ("ARM: S5PV210: Remove support for board files").

[RFT v2 2/5] ASoC: samsung: smdk_wm8580: Remove old platforms and drop mach-types usage

[Krzysztof Kozlowski]

MACH_SMDKC100, MACH_SMDKV210 and MACH_SMDKC110 are no longer supported
so we can drop the dead code.  After this the driver no longer
differentiates between machines (S3C24xx machines are not supported by
it) so there is no need to override I2S device id in cpu_dai_name and
SEC_PLAYBACK dai_link can be removed as well.

Not tested. The driver did not override .platform_name which looks
suspicious to me. However I did not want to add changes which could have
some visible impact on output code.

Changes since v1:
1. Squash two smdk_wm8580 patches and use ARRAY_SIZE(smdk_dai), after
   suggestion from Lars-Peter Clausen.
2. Remove also SEC_PLAYBACK dai_link.

The patch looks good to me. However the existing smdk64xx sound support
less so. I don't have smdk6410 set up for testing yet, possibly I get
around that next week.
Indeed it's strange .platform_name is not also "samsung-i2s.2".

I think that is a fallout from commit a08485d8fdf6f ("ASoC: Samsung: Do not
register samsung audio dma device as pdev"). Given nobody noticed this in
the last 4 years maybe its time to drop this machine driver as well.

Yeah, looks like since that commit things are broken.  Even though nobody
seems to be interested I'm inclined to not removing this machine driver
just yet, otherwise there will not be any board in mainline I could test
s3c64xx IP block related code changes. I'll try to find time to make this
working again.

MACH_SMDKC100, MACH_SMDKV210 and MACH_SMDKC110 are no longer supported
so we can drop the dead code.  After this the driver no longer
differentiates between machines (S3C24xx machines are not supported by
it) so there is no need to override I2S device id in cpu_dai_name and
SEC_PLAYBACK dai_link can be removed as well.

[PATCH v2 4/5] ASoC: samsung: Enable COMPILE_TEST for entire Samsung ASoc

[Krzysztof Kozlowski]

Instead of build time, Samsung ASoC drivers have rather runtime
dependency on Exynos or other Samsung platforms.  For building they
require Common Clock Framework.  If it is provided they could be compile
tested to increase build coverage.
