[PATCH 0/6] Baytrail-Cherrytrail updates

[PATCH 0/6] Baytrail-Cherrytrail updates

[Pierre-Louis Bossart]

As discussed on the alsa-devel mailing list, here is a set of patches to fix

1. previous feedback on bytcht_rt5651 - no new functionality beyond
what was already reviewed
2. cosmetic issues (variables in reverse xmas tree order, etc)
3. unnecessary clock tests

Since the changes are very small, I grouped them by machine
driver instead of generating more patches. let me know if a different
split is needed.

The last patch addresses Andy's comment that we should not use
strncmp(a,b,strlen(b)) when strcmp(a,b) is fine. This change is
applied across all machine drivers.

[PATCH 1/6] ASoC: Intel: bytcr_rt5651: add MCLK support and fix quirks

[Pierre-Louis Bossart]

Same as for other codecs, enable MCLK by default. When it is not
present, e.g. on MinnowBoard B3 since it's not routed on the LSE
connector, we fall back to blck-based clocking.

The DMIC quirks are also fixed, there is a single DMIC input of the
codec.

[PATCH 2/6] ASoC: Intel: bytcr_rt5651: filter codec name and fix variable declarations

[Pierre-Louis Bossart]

Use same fix as other codecs to work around BIOS/ACPI issues

Also reorder variables in reverse x-mas tree as suggested by Andy

Applied "ASoC: Intel: bytcr_rt5640: cosmetic fixes" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: bytcr_rt5640: cosmetic fixes

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

Applied "ASoC: Intel: cht_bsw_rt5645: cosmetic fixes" to the asoc tree

[Mark Brown]

The patch

   ASoC: Intel: cht_bsw_rt5645: cosmetic fixes

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

[PATCH 6/6] ASoC: Intel: boards: use strcmp with constant literals

[Pierre-Louis Bossart]

we used strncmp in all audio machine drivers, this is not needed
when comparing against constant literals.
General replace of strncmp(a, b, strlen(b)) to strcmp(a,b)

While we're at it: since all these do mostly same: wouldn't it make
more sense to create a helper to scan over the rtd_list?

static inline snd_soc_intel_get_codec_dai(struct snd_soc_card *card,
					  const char *dai_name)
{
	struct snd_soc_pcm_runtime *rtd;

	list_for_each_entry(rtd, &card->rtd_list, list) {
		if (!strcmp(rtd->codec_dai->name, dai_name))
			return rtd->codec_dai;
	}
	
	return NULL;
}

Some drivers require to check two names, but it can call this function
twice.


thanks,

Takashi

I like this!

It looks like not hot path, so, 2 passes instead of one might be not a
big deal.

Yes, that'd be a good way to simplify further. I'll resend the series,
