Subject: [PATCH 3.14 013/158] ARM: dts: omap4/5: Use l3_ick for the gpmc node

3.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Florian Vaussard <florian.vaussard@...l.ch>

commit 7b8b6af169a069454936053631d151a50af7b69a upstream.

The GPMC clock is derived from l3_ick. The simplest solution is
to reference directly l3_ick to provide the GPMC fck in order to
get correct timings. The real management of the clock is left to
hwmod.
