[PATCH 01/05] ARM: shmobile: r8a7779: Configure IRLM mode via DT

[PATCH 01/05] ARM: shmobile: r8a7779: Configure IRLM mode via DT

[Magnus Damm]

From: Magnus Damm <damm+renesas@opensource.se>

Adjust the r8a7779 SoC DTS and the Marzen Reference
C board code to use DTS only for INTC-IRQPIN IRLM setup.

 Initially written on top of renesas-devel-20141202-v3.18-rc7 and
 [PATCH] ARM: shmobile: r8a7779 CCF DTS update
 however applies cleanly to renesas-devel-20150215-v3.19

 Has a runtime dependency on:
 [PATCH 01/02] irqchip: renesas-intc-irqpin: r8a7779 IRLM setup support

ePAPR says: "The unit-address must match the first address specified in the
reg property of the node."

Hence it should be "irqpin0: irqpin@fe78001c {".
