drm/i915/display: Check PSR parameter and flag only in state compute phase
Due to the debugfs flag, has_psr2 in CRTC state could have a different value than psr.psr2_enabled and it was causing PSR2 subfeatures(DC3CO and selective fetch) to be set to not a expected state. So here only taking in consideration the parameter and debugfs flag when computing PSR state, this way the CRTC state will also have the correct state. intel_psr_fastset_force() was already broken as intel_psr_compute_config() was already only enabling PSR when psr_global_enabled() and all other PSR requirements are met. So some changes was required in this function, now it iterates over all connectors, if it is a eDP connector and is active force a modeset in the CRTC driving this connector, what will cause the new PSR state to be set based on the debugfs flag. v2: - end connector iterator in error cases Cc: Gwan-gyeong Mun <gwan-gyeong.mun@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20201007195238.53955-2-jose.souza@intel.com
