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 v1 series, this v2 series fixes errors raised
by the test kernel robot.
Best regards,
Herve Codina
Changes v1 -> v2:
- patch 2 and 6
Fix kernel test robot errors
- other patches
No changes

2.38.1
The CPM1 command mask is defined for use with the standard
CPM1 command register as described in the user's manual:
0 |1 3|4 7|8 11|12 14| 15|
RST| - |OPCODE|CH_NUM| - |FLG|
In the QMC extension the CPM1 command register is redefined
(QMC supplement user's manuel) with the following mapping:
0 |1 3|4 7|8 13|14| 15|
RST|QMC OPCODE| 1110|CHANNEL_NUMBER| -|FLG|
Extend the check command mask in order to support both the
standard CH_NUM field and the QMC extension CHANNEL_NUMBER
field.
