Subject: [Intel-gfx] [PATCH 05/11] drm/i915: Mark all HPD capabled connectors as such
Date: Tue, 21 Jan 2020 19:10:54 +0200	[thread overview]
Message-ID: <20200121171100.4370-6-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200121171100.4370-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Currently we only set the DRM_CONNECTOR_POLL_{DISCONNECT,CONNECT}
bits in intel_connector->polled (the base setting), leading to
some confusing looking code to reset drm_connector->polled
(the actual setting) to DRM_CONNECTOR_POLL_HPD. Let's set
intel_connector->polled = DRM_CONNECTOR_POLL_HPD for all hpd
capable connectors, and then we don't need so many special
cases in the hotplug code.
