2021-01-13drm/i915/hdcp: Move HDCP enc status timeout to headerAnshuman Gupta
DP MST stream encryption status requires time of a link frame in order to change its status, but as there were some HDCP encryption timeout observed earlier, it is safer to use ENCRYPT_STATUS_CHANGE_TIMEOUT_MS timeout for stream status too, it requires to move the macro to a header. It will be used by both HDCP{1.x,2.x} stream status timeout.

2021-01-13drm/i915/hdcp: DP MST transcoder for link and streamAnshuman Gupta
Gen12 has H/W delta with respect to HDCP{1.x,2.x} display engine instances lies in Transcoder instead of DDI as in Gen11. This requires hdcp driver to use mst_master_transcoder for link authentication and stream transcoder for stream encryption separately. This will be used for both HDCP 1.4 and HDCP 2.2 over DP MST on Gen12.

2020-04-03drm/i915: Pass atomic state to encoder hooksVille Syrjälä
We're going to want access to the atomic state for iterating the slave crtcs when enabling the port sync master crtc. Pass the atomic state all the way down. The alternative would be yet another encoder hook which we'll have to call after all the normal modeset stuff is done. Not really a fan of yet another hook just for this. Note that during readout state sanitation we are now going to pass NULL as the atomic state since we don't have one. We need to change that and then we can also s/crtc_state/crtc/ and s/conn_state/conn/ for the encoder hooks as well.

2019-12-09drm/i915/hdcp: Nuke intel_hdcp_transcoder_config()Ville Syrjälä
intel_hdcp_transcoder_config() is clobbering some globally visible state in .compute_config(). That is a big no no as .compute_config() is supposed to have no visible side effects when either the commit fails or it's just a TEST_ONLY commit. Inline this stuff into intel_hdcp_enable() so that the state only gets modified when we actually commit the state to the hardware.
