Subject: [PATCH 4.4 08/18] ARM: imx6: disable the GIC CPU interface before calling stby-poweroff sequence
Date: Thu, 14 Oct 2021 16:53:40 +0200 [thread overview]
Message-ID: <20211014145206.584373923@linuxfoundation.org> (raw)
In-Reply-To: <20211014145206.330102860@linuxfoundation.org>
From: Oleksij Rempel <o.rempel@pengutronix.de>
[ Upstream commit 783f3db030563f7bcdfe2d26428af98ea1699a8e ]
Any pending interrupt can prevent entering standby based power off state.
To avoid it, disable the GIC CPU interface.
Fixes: 8148d2136002 ("ARM: imx6: register pm_power_off handler if "fsl,pmic-stby-poweroff" is set")
