On TGL+ it's possible to have PSR1 enabled in other ports besides DDIA. PSR2 is still limited to DDIA. However currently we handle only one instance of PSR struct. Lets guard intel_psr_init_dpcd() against multiple eDP panels and warn about it. v2: Reword commit message to be TGL+ only and with the info where PSR1/PSR2 are supported (Lucas) Cc: Dhinakaran Pandiyan <dhinakaran.pandiyan@intel.com> Cc: Rodrigo Vivi <rodrigo.vivi@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Anshuman Gupta <anshuman.gupta@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190823082055.5992-6-lucas.demarchi@intel.com |
