Subject: [PATCH v6 03/18] drm/i915/hotplug: Handle CP_IRQ for DP-MST
Date: Thu, 26 Nov 2020 13:07:07 +0530 [thread overview]
Message-ID: <20201126073722.19107-4-anshuman.gupta@intel.com> (raw)
In-Reply-To: <20201126073722.19107-1-anshuman.gupta@intel.com>
Handle CP_IRQ in DEVICE_SERVICE_IRQ_VECTOR_ESI0
It requires to call intel_hdcp_handle_cp_irq() in case
of CP_IRQ is triggered by a sink in DP-MST topology.
