Subject: [Qemu-devel] [PATCH/RFC 3/6] clk: renesas: r8a7795: Mark the GPIO6 clock critical
Date: Fri,  9 Feb 2018 16:16:50 +0100	[thread overview]
Message-ID: <1518189413-2761-4-git-send-email-geert+renesas@glider.be> (raw)
In-Reply-To: <1518189413-2761-1-git-send-email-geert+renesas@glider.be>

The GPIO6 block will be exported to a guest.  As long as the guest won't
manage its module clock, it must be kept running by the host.

Not-Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>

TODO: Find a way to manage module clocks using PM Domains and Runtime
      PM on the guest.
