This patch adds support for the Hitachi TX23D38VM0CAA 9" WVGA TFT LCD panel to the simple-panel driver. This panel is connected via LVDS and uses the data enable signal for timing. Since HSYNC/VSYNC are ignored, the split between sync length and porches is arbitrary, as long as the complete horizontal blanking interval is 256 clocks, and the vertical blanking interval is 45 lines.
