* ASoC: max98095: Convert codec->hw_write to snd_soc_writeAxel Lin2011-10-221-7/+6Star
| | | | | | | | | | | | | | codec->hw_write is broken now, convert codec->hw_write to snd_soc_write. The hardware has 2 banks of registers sharing a section in I2C register space. The 1st bank is the primary one and is cached. The 2nd bank is for loading coefficients only and they do not need cache. These coefficients registers are therefore direct writes. Thus we set cache_bypass flag to deal with this before calling snd_soc_write.

* ASoC: twl6040: Request core to inline the DAPM sequencePeter Ujfalusi2011-10-141-0/+1
| | | | | | | | | | | | | | | | We need to have as less time between McPDM shutdown, and power down of the DAC on the twl6040 codec as possible. Request core to ignore the pmdown_time for the playback stream. Backround: with the McPDM protocol we are sendning not only the pure audio stream, but OMAP McPDM also transmits additional information (for example offset cancellation). If McPDM is stopped prior to the DAC this information will be not sent to the codec, which can result noise rendered by the twl6040 codec.
