4Subject: [PATCH 2/2] WIP: omap: beagleboard: add bbtoys ulcd-lite support
5
6Added support for the BeagleBoardToys ULCD-Lite.
7* Added ThreeFiveCorp s9700rtwv35tr-01b panel to
8 panel-generic-dpi driver.
9* Added TSC2007 and LCD panel to board file.
10
11Relied heavily on the TSC2007 integration work done by
12John Weber and panel timings from Roger Monk.
