[PATCH 06/08] mach-shmobile: KZM9D board Ethernet support V3

From: Magnus Damm
Date: Wed May 16 2012 - 02:45:55 EST


From: Magnus Damm <damm@xxxxxxxxxxxxx>

Tie in the on-board Ethernet controller on KZM9D
and make use of the GPIO controller for external
IRQ pin support.

Signed-off-by: Magnus Damm <damm@xxxxxxxxxxxxx>

Changes since V2:
- none, just bumped up version to match the V3 series

Changes from V1:
- none - this is the first public release
