Subject: OMAP5: Enable access to auxclk registers
X-Git-Tag: v2013.07-rc1~2^2~3^2~2
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=ee28edac4322602685ea12dc46edad1ec6b60487;p=oweals%2Fu-boot.git

OMAP5: Enable access to auxclk registers

auxclk0 and auxclk1 are utilized on some OMAP5 boards.
Define the infrastructure needed for accessing them
without using magic numbers.

Also remove unrelated TPS62361 defines from clocks.h
