Merge tag 'sti-fixes-for-v3.16-rc1' of git://git.stlinux.com/devel/kernel/linux-sti into fixes
Merge "STi: DT fixes for v3.16" from Maxime Coquelin:
Couple of DT fixes for STi platform issues discovered on V3.16-rc1.
The fixes included are:
- Ethernet clocks were wrongly defined for STiH415/416 platforms
- STiH416 B2020 revision E DTS file name contained uppercase, change to
lowercase.
