Subject: [PATCH] drm/panel: simple: Add display timing for HannStar HSD100PXN1

Add support for the Hannstar HSD100PXN1 to the DRM simple panel driver.

The HSD100PXN1 is an XGA (1024x768) panel with an 18-bit LVDS interface.
It supports pixel clocks in the range of 55-75 MHz.

This panel is offered for sale by Freescale as a companion part to its'
i.MX5x Quick Start board and i.MX6 SABRE platforms with under the name
MCIMX-LVDS1.
