Adam Ford 388adcbb08 ARM: dts: imx6q-logicpd: Enable ili2117a Touchscreen 
The LCD used with the imx6q-logicpd board has an integrated
ili2117a touch controller connected to i2c1.

This patch adds the node to enable this feature.

Adam Ford 6fd6d6f6a2 ARM: dts: imx6q-logicpd: Shutdown LCD regulator during suspend 
The LCD power sequencer is very finicky.  The backlight cannot
be driven until after the sequencer is done.  Until now, the
regulators were marked with 'regulator-always-on' to make sure
it came up before the backlight.  This patch allows the LCD
regulators to power down and prevent the backlight from being
used again until the sequencer is ready.  This reduces
standby power consumption by ~100mW.

Adam Ford 1c207f911f ARM: dts: imx: Add support for Logic PD i.MX6QD EVM 
The EVM consists of a system on module (SOM) and baseboard, and LCD.
This patch adds a DTSI file for the SOM and baseboard separately,
then a wrapper to combine them and specify processor type and a
LCD information.
