[PATCH 18/28] sh-pfc: r8a73a4: GPIO IRQ support

[Simon Horman]

From: Magnus Damm <damm at opensource.se>

V2 of code to add GPIO -> IRQ mappings to the
PFC table for the r8a73a4 SoC. Requires the IRQs
to be mapped at a fixed location in Linux IRQ
space. The actual IRQs are not handled by the
PFC, instead IRQC is used on r8a73a4.
