[PATCH/RFC,3/5] ARM: shmobile: r8a7790: Add INTC-SYS clock to device tree

Commit Message

Geert Uytterhoeven March 18, 2015, 7:16 p.m. UTC

Link the ARM GIC to the INTC-SYS module clock, so it can be power
managed using that clock in the future.

Note that currently the GIC driver doesn't support module clocks nor
Runtime PM.
