ARM: OMAP: remove plat/clock.h
Remove arch/arm/plat-omap/include/plat/clock.h by merging it into arch/arm/mach-omap1/clock.h and arch/arm/mach-omap2/clock.h. The goal here is to facilitate ARM single image kernels by removing includes via the "plat/" symlink. Signed-off-by: Paul Walmsley <paul@pwsan.com> [tony@atomide.com: fixed to remove duplicate clock.h includes] Signed-off-by: Tony Lindgren <tony@atomide.com>
