ES2.0 is a minor variant of ES1.1. ES2.0 is an incremental revision
with various fixes including the following:
- reset logic fixes
- few assymetric aging logic fixes
- MMC clock rate fixes
- Ethernet speed fixes
- edma fixes for mcasp
NOTE: even though we use a compatible of dra742 and dra752, the usage in
the Linux kernel is more or less interchangable - we use dra752 more
often in the linux kernel compared to dra742 and 4.2-rc6

based on linux-next next-20150812, applies to v4.2-rc6 as well.
Definetly not a 4.2 material, for 4.3, this probably missed the first merge
window for 4.3, will be great if it could be considered for the second merge
window.

I'll apply this into omap-for-v4.3/fixes thanks,
