Subject: [PATCH 5/8] drm/arm/malidp: Enable/disable interrupts in runtime pm
Date: Mon, 26 Mar 2018 18:03:17 +0100 [thread overview]
Message-ID: <1522083800-30100-6-git-send-email-ayan.halder@arm.com> (raw)
In-Reply-To: <1522083800-30100-1-git-send-email-ayan.halder@arm.com>
Display engine and core interrupts need to be disabled when the
system invokes malidp_runtime_pm_suspend. Consequently, they
need to be enabled in malidp_runtime_pm_resume.
