Subject: [ARM] omap: clks: call recalc after any rate change
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=b5088c0d90b898802318c62caf2320a53df6ce57;p=linux-2.6-omap-h63xx.git

[ARM] omap: clks: call recalc after any rate change

This implements the remainder of:
  OMAP clock: move rate recalc, propagation code up to plat-omap/clock.c
from Paul Walmsley which is not covered by the previous:
  [ARM] omap: move clock propagation into core omap clock code
  [ARM] omap: remove unnecessary calls to propagate_rate()
  [ARM] omap: move propagate_rate() calls into generic omap clock code
commits.
