Hi Colin,
Thank you for the patch.

Don't populate the read-only array clock_div_by_lanes on the stack but instead it static const. Also makes the object code a little smaller.

static const u8 clock_div_by_lanes[] = { 6, 4, 3 }; /* 2, 3, 4 lanes */It's not mandatory, but I have a tendency to declare static const variable first before all mutable variables.
hsw = mode->hsync_end - mode->hsync_start; hfp = mode->hsync_start - mode->hdisplay;I wonder if
/* set pixel clock divider mode */ regmap_write(adv->regmap_cec, 0x16, (12 / dsi->lanes) << 3);would be even better, or if it would be too much black magic. Either way,
