From 9e58523624fc063ce43ad3ef2bf6d603bda50a5e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Mon, 6 Mar 2017 17:58:07 +0100 Subject: [PATCH] ARM: dts: r8a7790: 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.
