Subject: [ARM] omap: move clock propagation into core omap clock code
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c6af45085211db8720d6b94b3985ce7198d764e3;p=linux-beck.git

[ARM] omap: move clock propagation into core omap clock code

Move the clock propagation calls for set_parent and set_rate into
the core omap clock code, rather than having these calls scattered
throughout the OMAP1 and OMAP2 implementations.
