[PATCH V3 0/2] reset: img: Add pistachio SoC reset support

[PATCH V3 0/2] reset: img: Add pistachio SoC reset support

[James Hartley]

This series provides the reset controller driver and documentation for the
pistachio SoC. 

Further platform support and a device tree will be posted via the MIPS
mailing list shortly.

These patches are based on linux-next.

Changes from V2:
	Following further feedback received from Philipp Zabel:
	- Moved pistachio-resets.h from 
		dt-bindings/reset-controller/ to
		dt-bindingd/reset/
	- Improved return code and mask handling 

Changes from V1:
	- Following feedback from Philipp Zabel, the reset controller node
	is now inside the cr_periph node which allows syscon to access via
	parent instead of looking up by phandle.

Hi James,

Thanks for the reminder. I'll apply these with a few small fixups.
No need to resend if you agree.

This should be aligned to the open parenthesis.

And this.

And one of these empty lines has to go.
