First, it's a rebased version of video start delay porch fix from Jagan Teki. The next patch fixes the overhead of HFP packet, according to the source code of BSP [1]. The final patch fixes DCS long write, which fixes initialization issue with a panel with ST7703 controller (XBD599 panel used by PinePhone). This seems to be a misread of [2]. (The formula in [2] is para_num+1, and the code of the sun6i_mipi_dsi driver uses tx_len, which is the length including the command; thus tx_len is equal to para_num+1, so it shouldn't be added with 1 for another time.)
