Subject: [PATCH v2 09/14] ARM: dts: imx6dl-colibri: Move common nodes to SoM dtsi
From: Max Krummenacher <max.krummenacher@...adex.com>
The following two nodes define module level functionality, move
them from the carrier board dts file to the SoM file.
While at it, reorder the properties in the gpio-keys node alphabetical.
- gpio-keys defining the wakeup pin
- memory node
The atmel touchscreen node can be used on any carrier board.
Move it from the carrier board to the module-level device tree and
keep it disabled.
Set the default pinmuxing to the dedicated connector available
on newer carrier boards and rename the pinctrl labels specifying
the INT/Reset signal to a common pattern.
pinctrl_atmel_conn - uses 107/106 pins as used on dedicated connector
pinctrl_atmel_adap - uses 28/30 pins as used with jumper wires
