There are drivers in mainline for the Xilinx Audio Formatter and Xilinx
I2S IP cores. However, because of a few issues, these were only really
usable with Xilinx's xlnx_pl_snd_card top-level driver, which is not in
mainline (and not suitable for mainline).
The fixes in this patchset, for the simple-card layer as well as the
Xilinx drivers, now allow these drivers to be properly used with
simple-card without any out-of-tree support code.
Changes since v1:
-formatting fixes
-renamed last_sysclk variables to sysclk
-require exact match for clock divisor rather than rounding to nearest
-broke out driver data structure change in xlnx_i2s to separate patch
-added constraints for sample rate based on sysclk to xlnx_i2s
-switched to separate function for DAI parsing for platforms in simple_card
