Subject: [PATCH 2/2] drm/panel: simple: Add support for Innolux LS075AT011

This adds support for the Innolux LS075AT011 7.5" 1200x900 panel. There's
no public data sheet for the panel -- the values have been taken from Ope=
n
Firmware and the documentation for the display controller that drives
the panel and tested on the OLPC laptop.
