[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.

Hi Philipp,

Yes that all looks fine to me.

Thanks,
