From c11333cc2e7ebe41e2aa4fa353abafa1f21a0662 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 6 Mar 2017 17:58:06 +0100 Subject: [PATCH] ARM: dts: r8a73a4: Add INTC-SYS clock to device tree Link the ARM GIC to the INTC-SYS module clock and the C4 power domain, so it can be power managed using that clock in the future. Note that currently the GIC-400 driver doesn't support module clocks nor Runtime PM, so this must be handled as a critical clock.
