==Background== The fsl_ssi driver was designed for PPC originally and then it has been updated to support different modes for i.MX Series, including SDMA, I2S Master mode, AC97 and older i.MXs with FIQ, by different contributors for different use cases in different coding styles.
Additionally, in order to fix/work-around hardware bugs and design flaws, the driver made a lot of compromise so now its program flow looks very complicated and it's getting hard to maintain or update.
So I am going to clean up the driver in both coding style level and program flow level.
==Introduction== This series of patches is the first set to clean up fsl_ssi driver in the coding style level. Any patch here is not supposed to change the program flow.
==Verification== Theoretically, it only needs code review, build and sanity tests. I have done build and sanity tests on an i.MX 6 platform by building using imx_v6_v7_defconfig and testing with I2S slave/master mode.
Thanks for your cleanup work.
Due to my current workload I will be able to go through this and test the AC'97 mode on a UDOO board only in about a week.
