Maintainer branches conflicts (using 3.13-rc7-dt-clks-v13):
=============================
Conflict resolution during rebase to maintainer's -14 branches:

1. (trivial) Against mike's clk-next dbdf6ff Merge branch
'clk-next-unregister' into clk-next

Could not apply 2edf7ad... CLK: TI: add DT alias clock registration
mechanism
conflict drivers/clk/Makefile (trivial fix)

2. (manual, but changes are easy) Against Tony's omap-for-v3.14/be
fc6ca98 ARM: OMAP: debug-leds: raw read and write endian fix

ARM: OMAP2+: clock: use driver API instead of direct memory read/write

conflicts with be changes on Tony's be branch.
commit 80f304dd2360cf5d50953c4eb4e902536f6a1263
    ARM: OMAP2+: raw read and write endian fix

Conflict:
arch/arm/mach-omap2/clkt_clksel.c
arch/arm/mach-omap2/clkt_dpll.c
arch/arm/mach-omap2/clkt_iclk.c
arch/arm/mach-omap2/clock.c
arch/arm/mach-omap2/clock36xx.c
arch/arm/mach-omap2/dpll3xxx.c
arch/arm/mach-omap2/dpll44xx.c

Both change raw_readls -> should now be just clk api instead which
already does readl_relaxed etc.. If Tony feels like, then we should
probably post a branch based on 'be' branch for easy merge.

3. I could not detect any merge conflict against Benoit's queued up
series (but maybe he has'nt pushed everything to remote tree)..

Boot reports:
=============
- previous orphan clocks seem solved.
- All available platforms seem to boot fine and no regression could be
seen on initial view
