[PATCH 0/4] ASoC: es828: various improvements

[Romain Perier]

This set of patches fixes clock handling in slave mode, enables
sampling frequency of 192khz in slave mode and adds support
for this frame rate in the driver rk3288_hdmi_analog.c.

[PATCH 1/4] ASoC: es8328: Simplify rates definition

[Romain Perier]

Currently most of the standard rates are supported by this driver.
Instead of defining each supported rate one by one, we use the SND macro
SNDRV_PCM_RATE_8000_48000. Also adds support for 88.2khz as the codec
supports it and the sys clocks are already supported.

Applied "ASoC: es8328: Simplify rates definition" to the asoc tree

[Mark Brown]

The patch

   ASoC: es8328: Simplify rates definition

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 2/4] ASoC: es8328: Let device auto detect ratios in slave mode

[Romain Perier]

In master mode, SCLK and LRCLK signals are generated by the CODEC when
any of the ADC/DAC are enabled. SCLK is derived from MCLK via a
programmable division set by BLK_DIV, LRCLK is derived from MCLK via
another programmable division set by ADCFsRatio/DACFsRatio.

In slave mode, SCLK and LRCLK signals are received as inputs and
supplied externally. LRCLK and SCLK must be synchronously derived from
MCLK with specific rates. The device can auto detect MCLK/LRCLK ratio
according to a predefined table. LRCLK/SCLK ratio is usually 64 (SCLK =
64 * LRCLK)

This commits adds support to let to device auto detect and decide which
ratio to use. The mclkdiv2 and BCLK_DIV ratio and put to zero.

[PATCH 3/4] ASoC: es8328: Enabling support for 192k

[Romain Perier]

The master and slave modes don't share the same table for MCLK/LRCLK
ratios. The slaves mode has bigger ratios that allow to use BCLK that
matche sampling frequency of 192khz.

This commit enables this rate only for slave mode, i.e it does not
declare this frequency in sysclk_contraints, resulting to an error in
master mode (not supported CLK).

Applied "ASoC: rockchip: Enable 192khz in hw_params operation" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip: Enable 192khz in hw_params operation

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: rockchip: Enable 192khz in hw_params operation

As the sampling frequency is supported by es8328 in slave mode,
add support for it in the corresponding operation.
