[PATCH] ASoC: tlv320aic32x4: Fix TAS2505/TAS2521 processing block selection

[Marek Vasut]

The TAS2505/TAS2521 does support only three processing block options, unlike
TLV320AIC32x4 which supports 25. This is documented in TI slau472 2.5.1.2
Processing Blocks and Page 0 / Register 60: DAC Instruction Set - 0x00 / 0x3C.

Limit the Processing Blocks maximum value to 3 on TAS2505/TAS2521 and select
processing block PRB_P1 always, because for the configuration of teh codec
implemented in this driver, this is the best quality option.

Thanks!

[1/1] ASoC: tlv320aic32x4: Fix TAS2505/TAS2521 processing block selection
      commit: 090c57da5fd59fb59adc9d9341a77558c93b0abd

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
