[PATCH 03/12] ARM: dts: imx6ul-isiot: Add imx6ul-isiot-common.dtsi

[Jagan Teki]

From: Jagan Teki <jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>

lcdif nodes are differ wrt specific LCD connected on Is.IoT MX6UL
module, so create separate file 'imx6ul-isiot-common.dtsi' for common
lcdif node structure and include the same on respective dts.

More common nodes will add in future patches.

Label a MFD device 'touch'?  Also, the node name should be generic.  Not
sure what should be used for MFD device though.

If this is for stmpe-ts, shouldn't be put into touchscreen child node?

May be I can use stmpe811@41 the existing imx6qdl-apalis.dtsi using
the similar notation.

Actually this is interrupt pad, for the touch controller via stmpe so
I can rename pinctrl_touch_int.

stmpe_touchscreen {

This is also compatible with existing dtsi files

Per application notes of stmpe811 below, I would suggest you name it
gpio-expander.

[PATCH 11/12] ARM: dts: imx6dl-icore: Add touchscreen node

[Jagan Teki]

From: Jagan Teki <jagan@amarulasolutions.com>

max11801 touchscreen on Engicam iCoreM6 DualLite/Solo module is
connected via i2c1, so add max11801: touchscreen@48 on i2c1.
