[PATCH v3 00/10] Add the PowerQUICC audio support using the QMC

Hi,

This series adds support for audio using the QMC controller
available in some Freescale PowerQUICC SoCs.

This series contains three parts in order to show the different
blocks hierarchy and their usage in this support.

The first one is related to TSA (Time Slot Assigner).
The TSA handles the data present at the pin level (TDM with up
to 64 time slots) and dispatchs them to one or more serial
controller (SCC).

The second is related to QMC (QUICC Multichannel Controller).
The QMC handles the data at the serial controller (SCC) level
and splits again the data to creates some virtual channels.

The last one is related to the audio component (QMC audio).
It is the glue between the QMC controller and the ASoC
component. It handles one or more QMC virtual channels and
creates one DAI per QMC virtual channels handled.

Compared to the v2 series, this v3 series mainly:
  - adds modification in the DT bindings,
  - uses generic io{read,write}be{16,32} for registers
    accesses instead of the specific PowerPC ones.
  - updates some commit subjects and logs (CPM1 SoCs supports).

Best regards,
Herve Codina
