Why will you add yourself in the MAINTAINERS file for those drivers when
git shows just one contribution for the mips-gic-timer for the timer
stability ?

Also, in the cpuidle-cps.c history, there is no signed-off from Rafael,
neither an Acked-by when it was merged. That make me think the patch
went through another path than the linux-pm tree without a cpuidle
framework maintainer acknowledgement.

Perhaps it is a mistake and the patch was actually acked-by, but I would
like to remind the patches have to be acked by the upper maintainers and
being listed in the MAINTAINERS file does not give the right of override
this rule.

I suppose that the number of commits isn't a main criteria to make someone of
being a maintainer of a particular driver, though it might be a sufficient
condition why someone could be appointed with the role. Anyway as I said in
the cover letter that was a mere suggestion:

Primarily I've propose my help with looking after those drivers, since I'll be
working on our SoC drivers with those components installed anyway.

Another reason why I've decided to create this patch is that I've discovered there
is noone looking after the drivers/bus/mips_cdmm.c driver. Noone responded to
accept/decline the CDMM-related changes proposed in this patchset
(mips_cdmm.c driver), noone except Rob responded to the DT bindings conversion
patches (irq-mips-gic.c, mips_cdmm.c drivers):
  68d4fa5d0bb8 dt-bindings: bus: Add MIPS CDMM controller
  7256641fe15e dt-bindings: interrupt-controller: Convert mti,gic to DT schema
  da16cdddd947 dt-bindings: power: Convert mti,mips-cpc to DT schema
Finally I didn't say it in the cover letter, but cpuidle-cps wasn't working for
our SoC, so I'll have to dig into that driver anyway. Moreover It seems to me
that cpuidle-cps.c will be abandoned by the author since Paul Burton stopped
working for MIPS. So based on that I collected all MIPS-related but scattered
around the kernel subsystems drivers (MIPS CDMM, MIPS CPU/GIC IRQ-chip,
MIPS GIC-timer and MIPS CPU-idle CPS) in the dedicated maintainers entry and
proposed my help with their maintenance. By Marc' suggestion Thomas agreed to
join in.

If you don't need our help in maintaining the mips-gic-timer.c and cpuidle-cps.c
drivers, then just say so. I'll discard them from the maintenance entry created
by this patch. Though in that case the list won't be full.)

Sorry. I don't really get it what patch you are talking about. But I
totally aware of the rule you've mentioned.
