I don't think this driver needs my ack, see below, ...

... but that is a good idea to keep me in the loop. I will send a patch.

This keystone reset driver handles the CPU/SoC reset via soft reset bit.
This does not directly concern the reset controller framework, as it is
not used by this driver.
The reset framework is intended mainly to control reset lines to
peripheral devices that don't stop execution as soon as they are
asserted.
Of course rsctrl_restart() could be modeled as a reset controller using
the framework instead, but I don't think it has to. There already is
other (older) reset code similar to this in various places (such as
arch/arm/mach-pxa/reset.c).

Of course the overlap in terminology (complete system reset vs
peripheral resets) is a bit unfortunate, but I'm not sure what we can do
about this.
