Subject: [PATCH] ARM: OMAP3+: DPLL: stop reparenting to same parent if already done
Date: Wed, 5 Feb 2014 03:04:08 -0600 [thread overview]
Message-ID: <1391591048-19433-1-git-send-email-nm@ti.com> (raw)
omap3_noncore_dpll_set_rate forces a reparent to the same clk_ref
for every call that takes place. This is an can be done only if a change
is detected.
