Subject: [PATCH/RFC 5/5] ARM: shmobile: r8a7794: Add INTC-SYS clock to device tree
Date: Wed, 18 Mar 2015 20:16:04 +0100 [thread overview]
Message-ID: <1426706164-28309-6-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1426706164-28309-1-git-send-email-geert+renesas@glider.be>
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.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
