Lee Jones 7cf261dd1e ARM: ux500: Change IRQ from low-to-high edge triggered to high-to-low
When the STMPE IRQ is triggered to be active high level-sensitive, the
Nomadik GPIO controller it uses complains, although it still works.
Recently we attempted to move triggering to low-to-high in an attempt
to prevent the warning; however, this ensured that the IRQ was actually
missed completely. Now we have a solution which both works and keeps the
GPIO controller happy.

Lee Jones 98c52c7c67 ARM: ux500: Change the type of interrupt to something compatible
On boot the Nomadik GPIO controller complains that an IRQ can't be
configured as active high level-sensitive, so this patch converts
it to be low-to-high edge triggered instead.

Lee Jones 092778190d ARM: ux500: Supply the STMPE keypad Device Tree node to the STUIB DT
This patch allows the STMPE keypad driver to be successfully probed
and initialised during a Device Tree enabled boot sequence. It
contains all of the required properties needed to setup and map
each key on the 6x3 keypad located on the ST User Interface Board.

Lee Jones cb5527035d ARM: ux500: Apply a Device Tree node for the STMPE MFD
Here we apply the STMPE Multi-Functional Device's node to the
ST User Interface Board Device Tree file. It includes all of
the properties required for correct device initialsation.

Lee Jones cbebba7d86 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.
