Hi,
Changes since v1: - Do not calculat that we allow one serializer in DIT mode, just set the max_active_serializers to 1. Reported-by: kernel test robot lkp@intel.com
it has been on my todo list for several years to support McASP on OMAP4 devices. For Galaxy Nexus we had an omap-mcasp driver (which was mostly a stripped down davinci-mcasp driver) to support what was needed on that specific phone + it's dock for S/PDIF (48KHz, 16bit, stereo).
Not many (if any) device available to test the DIT mode of McASP. I have used BeagleBone White (McASP1 AXR3 can be routed to a pin) to get the S/PDIF mode working then PandaES for OMAP4 support (on PandaES the gpio_121 is not used and the signal is routed to expansion J6 pin14).
In theory the McASP in OMAP5 should be working after this series, but the OMAP5 TRM is not public and I do not have one to check the addresses and see if there is a way to test it on omap5-uevm.
Mark, Tony: The ASoC and dts patches can go via separate tree I felt that it is better if they are together, at least initially.
Nikolaus: fyi, this might be useful for Pyra?
