Jani Nikula e6f577893d drm/i915/dsi: fix CHV dsi encoder hardware state readout on port C ... Due to "some hardware limitation" the DPI enable bit in port C control register does not get set on VLV. As a workaround we check the status in pipe B conf register instead. The workaround was added in commit c0beefd29f Author: Gaurav K Singh <gaurav.k.singh@intel.com> Date: Tue Dec 9 10:59:20 2014 +0530 drm/i915: Software workaround for getting the HW status of DSI Port C on BYT Empirical evidence (on Surface 3 with DSI on port C per VBT) shows that this is the case also on CHV, so extend the workaround to CHV. We still have the device ready register check in place, so this should not get confused with e.g. HDMI on pipe B. This fixes a number of state checker warnings on CHV DSI port C.
