Due to similarity panel replay dpcd initialization got added in psr
function which is specific for edp panel. This patch enables panel
replay initialization for dp connector.

If panelreplay initialization then why is the function name psr_init_dpcd() ?
Also it its similar to PSR then these dpcd should already be available.

Thanks and Regards,

Hi Arun,

The first call for intel_psr_init_dpcd() get called from intel_edp_init_dpcd() which is not reachable for DP.
So, in this patch need to add intel_psr_init_dpcd() for DP(non-edp) in intel_psr_init().
Panel replay initialization added in intel_psr_init() as per previous feedback just to align panel-replay with psr framework.

Animesh
