> Amend cpsw controller to optionally take a pin control handle and set
> the state of the pins to:
> 
> - "default" on boot, resume
> - "sleep" on suspend()
> 
> This should make it possible to optimize energy usage for the pins
> for the suspend/resume cycle.
> 
> If any of the above pin states are missing in dt, a warning message
> about the missing state is displayed.
> If certain pin-states are not available, to remove this warning message
> pass respective state name with null phandler.

This still needs some work:

> +		/*
> +		* Since we continue even when pinctrl node is not found,
> +		* Invalidate pins as not available. This is to make sure that
> +		* IS_ERR(pins_xxx) results in failure when used.
> +		*/

The second, third, fourth, and fifth lines are not tabbed correctly.  They
should all be two TABs and a SPACE.

Secondly, comments in the networking are to be formatted:

	/* Like
	 * this.
