do you have this series on your radar somewhere or should Tony
resend the series? As it looks like it fell through the cracks somehow.

do you have some sort of merge plan for this or are you waiting for
specific Acks? I guess if we're waiting for an Ack from Mark Brown,
we'll need a resend of the patch.

All other patches have Acks from their subsystem maintainers (rtc, clk)
so you could pick up all patches except patch3 and I could just resend
this one, which in turn could also go through the regulator tree.

Otherwise we'll probably need a resend of the series, as Mark most of
the time doesn't keep old patch series around.

Try resending it.  Hopefully he will review in the next week or so can
I can collect it when I return back from Shared Parental Leave.

[PATCH v7 2/6] mfd: rk808: Add RK817 and RK809 support

[Tony Xie]

The RK809 and RK817 are a Power Management IC (PMIC) for multimedia
and handheld devices. They contains the following components:
  - Regulators
  - RTC
  - Clocking

Both RK809 and RK817 chips are using a similar register map,
so we can reuse the RTC and Clocking functionality.
Most of regulators have a some implementation also.
