Merge tag 'renesas-boards-for-v3.11' of git://git.kernel.org/pub/scm/linux/kernel/git/horms/renesas into next/boards

From Simon Horman:
Renesas ARM-based SoC board updates for v3.11

Highlights:
bockw: add SDHI0 support
bockw: add dummy regulators for SMSC
bockw: Document CN9 SCIF/RCAN dipswitch selection
lager: support GPIO switches and LEDs
kzm9g: add AS3711 PMIC platform data
marzen: Use INTC External IRQ pin driver for SMSC
ape6evm: Update MP clock parent become EXTAL2 in line with changes
         to r8a73a4 SoC code
