drm/panel: simple: Add support for Giantplus GPG482739QS5
This patch adds support for the GiantPlus GPG48273QS5 4.3" WQVGA TFT LCD panel to the simple-panel driver. This panel is connected via a parallel bus and uses both HSYNC and VSYNC, whose lengths are unfortunately not clearly defined. The datasheet only specifies the front- and backporch length, but the timing diagram suggests that both sync signals should be asserted for exactly one clock cycle.
