Hi, This series addressed almost all comments from Thierry Redding and Russell on v1. This series adds support for i.MX MIPI DSI DRM driver. Currently, the MIPI DSI driver only supports the burst with sync pulse mode. This series also includes a DRM panel driver for the Truly TFT480800-16-E panel which is driven by the Himax HX8369A driver IC. The driver IC data sheet could be found at [1]. As mentioned by the data sheet, the driver IC supports several interface modes. Currently, the DRM panel driver only supports the MIPI DSI video mode. New interface modes could be added later(perhaps, just like the way the DRM simple panel driver supports both MIPI DSI interface panels and simple(parallel) interface panels). The MIPI DSI feature is tested on i.MX6Q SabreSD board and i.MX6DL SabreSD board. The MIPI DSI display could be enabled directly on i.MX6Q SabreSD board after applying this series, because the 26.4MHz pixel clock the panel requires could be derived from the IPU HSP clock(264MHz) with an integer divider. On i.MX6DL SabreSD board, we need to manually disable the LVDS and HDMI displays in the device tree blob, since the i.MX6DL IPU HSP clock is 198MHz at present, which makes the pixel clock share the PLL5 video clock source with the LVDS and HDMI, thus, the panel cannot get the pixel clock rate it wants. Patch 01/15 is needed to get a precise pixel clock rate(26.4MHz) from the PLL5 video clock. If we don't have this patch, the pixel clock rate is about 20MHz, which causes a horitonal shift on the display image. This series can be applied on the drm-next branch.
