Subject: [PATCH 0/4] ASoC; davinci-mcasp: Pin handling updates

Hi,

The series will improve the McASP pin handling:
- To avoid non configured clocks leaking out from McASP
- make sure that the AXR pin (TX) state is correct in all scenarios
- Allow user configurable DISMOD for the tx pin instead of hardwiring it in the
  code to low

The DISMOD configuration is needed when the codec requires the TX line to be
high during inactive slots (mu-law codecs for example).

Regards,
Peter
