[PATCH 2/2] drm/panel: Add support for Giantplus GPG482739QS5 panel

[Lucas Stach]

From: Philipp Zabel <philipp.zabel@gmail.com>

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.

Hi Thierry,

just a gentle ping for those 2 patches. It would be nice if you could
pick them up, so they can go into the next mergewindow.

Regards,
Lucas

It's too late to make v3.19, but I've queued these for v3.20, thanks.
