Subject: [PATCH] drm/i915/panelreplay: Move out psr_init_dpcd() from
init_connector()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Move psr_init_dpcd() from init-connector to connector-detect
function. The dpcd probe for checking panel replay capability
for external dp connector is causing delay during boot which can
be optimized by moving dpcd probe to connector specific detect().
v1: Initial version.
v2: Add details in commit description. [Jani]
