Hi,
this series will enable analog audio (via onboard aic310x codec) for dra7-evm,
dra72-evm and am57xx-beagle-x15 boards.
In these board McASP3 is connected to the codec and for the McASP3 we needed to
have the DMA crossbar in place since the request lines are not mapped by
default.
Regars,
Peter

Use the name for the supply as it is in the schematics since the same
supply is used for other peripherals than MMC2, like audio.
