This patchset contains several fixes to the sun6i_mipi_dsi driver.

First, it's a rebased version of video start delay porch fix from Jagan

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.)

  drm/sun4i: sun6i_mipi_dsi: fix DCS long write packet length

  drm/sun4i: dsi: Fix video start delay computation
