I'm worry a bit, if you will apply this series in its current order
- it will break git bisect.
Patch one "ARM: OMAP2+: Fix timer entries for dm814x" will use timerX_fck, but those
clocks will be added by patches 2 "clk: ti: Add few dm814x clock aliases"
and 8 "ARM: dts: Fix some mux and divider clocks to get dm814x-evm booting"
