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 and multiple ways of combining the fifos for each data line.
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.
Patches 1 and 2 from Lucas enhance per SOC handling of SAI properties. Patches 3,4,5,6,7,8 allow SAI driver to read active data lines and fifo combine mode from DT. Patch 9 fixes new SAI register address space. Patch 10 enable SAI for imx7ulp and imx8mq.
