This patchset fixes some portion of timing calculation in sun6i_mipi_dsi driver according to the BSP driver.
Two of the patches are reverting, one is fixing some misread of the BSP source code, another is fixing a wrong refactor that actually breaks the formula.
The other non-reverting patch is fixing a porch error which is usually seen in the original driver commit. Most of porch errors are then fixed, but this one gets ignored.
By applying these patches, several DSI panels are tested to be driven properly by the timing provided by the vendor, including the LCD panel of PinePhone "Don't Be Evil" DevKit, the final PinePhone panel and the panel on PineTab. Without these patches they need dirty timing hacks to work.
