So far SAI IPs integrated with imx6 only supported one data line.
Starting with imx7 and imx8 SAI integration support up to 8 data
lines. First patch introduce register definition to support this.
New SAI IP version introduces two new registers (Version and Parmeter
registers) which are placed at the beginning of register address space.
For this reason we need to fix the register's address. Support for
this is introduced in patch 3.
Changes since v2:
- removed patches regarding data line mask because I need to
find a better way to describe to model data lines. Perhaps,we
only need to specify how many datalines a specific SAI instance
supports and then let SAI driver to activate datalines based on
the number of channels. Will open the discussion on this on a
separate thread.
- fixed devicetree documentation as per Nicolin comments and
will send a separate patch to convert it to yaml.
Changes since v1:
- removed patches from Lucas as they were already accepted
- addressed comments from Lucas and Nicolin regarding
device tree property naming
- removed comment saying that "datalines" must be always
consecutively enabled (this is not true, checked with IP owner)
- added new patch to document newly introduced compatbile
strings
- removed patch introducing combined mode as I will still need
some time to figure out how to properly allow users to set it.
