Subject: [PATCH 4.4.y-cip] ARM: dts: iwg22d-sodimm: Enable touchscreen

From: Marian-Cristian Rotariu

commit 99ae78f1fc3a73c88fe726c676ae963ce722bf20 upstream.

In one of the iWave-G22D development board variants, called Generic
SODIMM Development Platform, we have an LCD with touchscreen. The
resistive touch controller, STMPE811 is on the development board and
is connected through the i2c5 of the RZ-G1E.

Additionally, this controller should generate an interrupt to the CPU
and it is connected through GPIO4,4 to the GIC.

Touch was tested with one of our iW-RainboW-G22D-SODIMM RZ/G1E
development platforms.

More details on the iWave website:

There seems to be no issue with this patch, but we also need to update
We need to enable the below configs in shmobile_defconfig. Currently this configs are not enabled in
Mainline. Not sure we should upstream this and backport it or Just enable it in cip-kernel-config? Please let me know.
