[PATCH 09/10] ARM: ux500: Add all bu21013 touch screen components to supported Device Trees

Tue Oct 2 04:13:22 EDT 2012


It is possible to connect a BU21013 Touch Screen to all version
of the HREF which support the ST-UIB. This patch applies all the
necessary settings to the pre-v60 and v60+ HREF Device Trees.
