[v2,2/3] ARM: shmobile: emev2: Add clock tree description in DT

Commit Message

[e-mail] Oct. 8, 2013, 5:33 a.m. UTC

Add minimum clock tree description to .dts file.
This provides same set of clocks as current sh-clkfwk version .c
code does.

Thanks.

I plan to add this patch to a new topic branch,
topic/emev2-common-clock, in the renesas tree and
queue it up from there for inclusion in mainline
if/when the first patch of this series is accepted
by Mike Turquette.
