Subject: [RFCv3 0/4] Adding support for Zynq Reset Controller

Hi all,

I made another RFC addressing most of the feedback that I got so far.

I haven't completly given up on Sören's idea of getting rid of having
some sort of protection against people using wrong bits by accident,
but haven't come up with a clean way to do so yet (especially when looking at
the possiblity of also supporting the upcoming Zynq's reset controller).

I changed the reg property to <0x200 0x48> but I'm not sure if that's correct.
At 0x24C there's the RS_AWDT_CTRL which is not a reset. The last legit one
is A9_CPU_RST_CTRL at 0x244.

As Michal requested I removed the #include syntax from the devicetree bindings.

Thanks for your reviews,

Moritz
