6a4500c7b83f9e Colin Xu 2021-02-26 453 * So the correct sequence to find DP stream clock is:
6a4500c7b83f9e Colin Xu 2021-02-26 454 * Check TRANS_DDI_FUNC_CTL on TRANSCODER_A to get PORT_x.
6a4500c7b83f9e Colin Xu 2021-02-26 455 * Check correct PLLx for PORT_x to get PLL frequency and DP bitrate.
6a4500c7b83f9e Colin Xu 2021-02-26 456 * Then Refresh rate then can be calculated based on follow equations:
6a4500c7b83f9e Colin Xu 2021-02-26 457 * Pixel clock = h_total * v_total * refresh_rate
6a4500c7b83f9e Colin Xu 2021-02-26 458 * stream clock = Pixel clock
6a4500c7b83f9e Colin Xu 2021-02-26 459 * ls_clk = DP bitrate
6a4500c7b83f9e Colin Xu 2021-02-26 460 * Link M/N = strm_clk / ls_clk
