The Broadcom STB PCIe RC uses a reset control "rescal" for certain chips.
The "rescal" implements a "pulse reset" so using assert/deassert is wrong
for this device.  Instead, we use reset/rearm.  We need to use rearm so
that we can reset it after a suspend/resume cycle; w/o using "rearm", the
"rescal" device will only ever fire once.

Of course for suspend/resume to work we also need to put the reset/rearm
calls in the suspend and resume routines.

Actually - I am sorry but it looks like you will have to split the patch
in two since this is two logical changes.

I do not believe this can be easily split, since there is currently a
misused of the reset controller API and this patch fixes all call sites
at once. It would not really make sense to fix probe/remove and then
leave suspend/resume broken in the same manner.

Right - I was reading the previous versions of the set, it makes sense
to keep it in one logical change.

Do you want me to take it or you prefer an ACK so that it can go via
a different tree ?

Thanks,
Lorenzo
