Applied "ASoC: samsung: i2s: Support more resolution rates" to the asoc tree

[Mark Brown <broonie@kernel.org>]

The patch

   ASoC: samsung: i2s: Support more resolution rates

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

Subject: [PATCH] ASoC: samsung: i2s: Support more resolution rates

This driver can support more frequencies over 96KHz. There are no reasons
to limit the frequency range below 96KHz. If codecs/amps or something else
can't support higher resolution rates, the constraints would be set rates
properly because each drivers have its own limits.

I added the 'pcm_rates' field to the dai_data to be set rates by the
compatibilities. As a result, rates will be set each devices respectively.
For example of exynos5433, rates will be set from 8KHz to 192KHz.
