So did you verify that the register really is a transcoder register? Eg. set PIPE_MULT(A) to 1x and use pipe A to drive the EDP transcoder. I did not verify. This change was done based on the fact that the register does not exist in the VPG HTML version of the BPEC for Transcoder_EDP,

From: Clint Taylor clinton.a.tay...@intel.com Haswell and later silicon has added a new pixel replication register to the pipe timings for each transcoder. Now in addition to the DPLL_A_MD register for the pixel clock double, we also need to write to the TRANS_MULT_n (0x6002c) register to double
