From: Eberhard Stoll <eberhard.stoll@xxxxxxxxxx> I'm currently working on a board with stm32mp157 SOC which contains a synposys LTDC to DSI bridge (drm/stm/dw_mipi_dsi-stm.c). In this configuration i observe a overclocking of the LVDS pixel clock. The reason for this is, that the synopsys bridge increases the DSI lane clock by 20% for burst mode. On the other hand the sn65dsi83 chip uses the DSI lane clock to generate LVDS pixel clock. So in this configuration the LVDS pixel clock is 20% higher as the panel configuration pretends. Removing burst mode solves this issue. It also seems sensible to me, that a fixed divider to generate the pixel clock out of the DSI lane clock is not compatible with burst mode. But i'm not sure if i'm missing someting in the big picture and whether this issue should be solved somewhere else.
