[PATCH v4 3/3] ARM: mach-shmobile: r8a7740: Setup the serial devices using DT
Bastian Hecht

Mon Mar 4 11:20:54 EST 2013
We can now use the Device Tree for bringing up our serial devices on
the SoC r8a7740.
We remove the power domain association. We will move the info into the
DT setup as soon as we have support for it. For now this is fine as we
use the power domain governor "pm_domain_always_on_gov" for A3SP.

v4:
We don't move the DT into the r8a7740-armadillo800eva-reference.dts, but
r8a7740.dtsi as the serial device setups are not dependent on any board
confguration.
Renamed sci at 0xe6c40000 to sci at e6c40000
