[alsa-devel] [PATCH] ASoC: Intel: kbl: Move codec sysclk config to codec_init function
From: Mac Chiang mac.chiang@intel.com
unexpected error: PLL input clock 0 below valid range
backport from broonie's tree commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function")
The MCLK for DA7219 does not change in this platform, but is currently being configured everytime as part of the platform_clock event handler for DAPM. The upshot of this is that we have unnecessary calls to this function, and it also means that if a stream hasn't yet been started, DA7219 driver does not have the correct MCLK rates programmed and so the HP detection feature does not operate as expected.
This patch rectifies this issue by moving the sysclk call to codec_init function so it's only called once at initialisation.

Mac, I provided you internal feedback that your commit message was misleading. This is not a 'backport', the intent here is to fix a problem on KBL using the same solution already merged for ApolloLake with commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function"). You also want to be careful when including someone else's Signed-off-by and check for typos, if you run checkpatch.pl --strict you'd see this:
WARNING: 'everytime' may be misspelled - perhaps 'every time'? #14: currently being configured everytime as part of the platform_clock
WARNING: Non-standard signature: Singed-off-by: #26: Singed-off-by: Mac Chiang mac.chiang@intel.com
CHECK: Alignment should match open parenthesis #57: FILE: sound/soc/intel/boards/kbl_da7219_max98357a.c:170: + ret = snd_soc_dai_set_sysclk(codec_dai, DA7219_CLKSRC_MCLK, 19200000, + SND_SOC_CLOCK_IN);
total: 0 errors, 2 warnings, 1 checks, 32 lines checked
In addition, both Adam and I mentioned that the clocks are different between the two platforms, so this patch is incorrect and cannot be applied as is, see below.

That is clearly wrong. Likely a copy/paste from bxt_da7219_max98357a.c instead of moving the code within the same file.

As Pierre mentioned yesterday, this is not an existing patch being reapplied, so you cannot assume people's 'Signed-off-by' on this. Mark certainly won't add his 'Signed-off-by' tag until he merges it into his tree. Also, has Sathya actually seen this actual change? If not how can you add his 'Acked-by' tag?
If you can make this patch format in-line with normal expectations, then the code below looks ok to me.

fix an issue on KBL which applied the merged solution from broonie's tree commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function")
This is confusing cause and effect. I suggest you start with the description of the APL fix:
'On APL, commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function") fixed an issue related to jack detection.'
then keep the following working as is
The MCLK for DA7219 does not change in this platform, but is currently being configured everytime as part of the platform_clock event handler for DAPM. The upshot of this is that we have unnecessary calls to this function, and it also means that if a stream hasn't yet been started, DA7219 driver does not have the correct MCLK rates programmed and so the HP detection feature does not operate as expected.
add 'The same fix is needed on KBL.'

same here, the code makes sense. I will ack this patch once the commit message and tags are fixed. Please submit a v3 and read [1] before doing so.

The patch
ASoC: Intel: kbl: Move codec sysclk config to codec_init function
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

From: Mac Chiang mac.chiang@intel.com Date: Fri, 1 Jun 2018 01:18:32 +0800 Subject: [PATCH] ASoC: Intel: kbl: Move codec sysclk config to codec_init function
On APL, commit fd0f237572ad ("ASoC: Intel: bxt: Move codec sysclk config to codec_init function") fixed an issue related to jack detection.
The MCLK for DA7219 does not change in this platform, but is currently being configured everytime as part of the platform_clock event handler for DAPM. The upshot of this is that we have unnecessary calls to this function, and it also means that if a stream hasn't yet been started, DA7219 driver does not have the correct MCLK rates programmed and so the HP detection feature does not operate as expected.
The same fix is needed on KBL.
This patch rectifies this issue by moving the sysclk call to codec_init function so it's only called once at initialisation.
