[PATCH V6 0/3] Add support for Tegra210 ADMA

[Jon Hunter <jonathanh-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>]

Add support for the Tegra210 Audio DMA (ADMA) controller which is part
of the Audio Processing Engine and used for transferring audio data.

V6 changes:
- Removed stub function tegra_adma_prep_slave_sg() as it is no longer
  needed.

V5 changes:
- Removed APE and APE2APB clocks as these clocks rightfully belong
  in the ACONNECT bus driver [0] and the ADMA is child of this device.
  Dropped power-domain from DT binding as this will be handled by
  ACONNECT bus driver as well.
- Minor update to case statement formatting based upon feedback from
  Vinod.
- Make ADMA dependent on Tegra210 as this is the only device
  (currently) that supports it.

V4 changes:
- Updated DT binding to include 'power-domains' entry for handling
  the APE power domain inconjunction with runtime-pm.
- Added missing clocks to the DT binding that were being handled by
  the bootloader.
- Added support for PM_CLK to simplify clock handling

V3 changes:
- Updated DT binding per feedback from Mark and Stephen
- Fixed up items mentioned by Vinod

V2 changes:
- Re-worked device-tree binding
