Subject: ARM: ux500: Add all bu21013 touch screen components to supported Device Trees
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=cbebba7d8640105d9caf197c1f31d3360db4e1c7;p=deliverable%2Flinux.git

ARM: ux500: Add all bu21013 touch screen components to supported Device Trees

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.
