[PATCH v2 09/10] ARM: dts: berlin: convert BG2 to DT clock nodes
From: Sebastian Hesselbarth
Date: Wed May 14 2014 - 16:15:51 EST
This converts Berlin BG2 SoC dtsi to make use of the new DT clock
nodes for Berlin SoCs. While at it, also fix up twdclk which is
running at cpuclk/3 instead of sysclk.
Signed-off-by: Sebastian Hesselbarth <sebastian.hesselbarth@xxxxxxxxx>

Changelog:
v1->v2:
- dropped of_clk_create_name() usage required unique node names for
clocks and plls
- added clock-output-names to allow fixed-factor-clock to find its
parent name
