From 133a3f1a19c99218a39e9d3e91e9e5442fa0f191 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 6 Mar 2017 17:58:11 +0100 Subject: [PATCH] ARM: dts: r8a7794: Add INTC-SYS clock to device tree Link the ARM GIC to the INTC-SYS module clock, and add it to the "always on" PM Domain, so it can be power managed using that clock. Note that currently the GIC-400 driver doesn't support module clocks nor Runtime PM, so this must be handled as a critical clock.
