Document bindings for regulators (3 bucks, 3 LDOs and 2 LED
drivers) and 4 GPIO pins which can be configured for I/O or
as interrupt sources withe configurable trigger levels.

'dt-bindings: mfd: ...' for the subject.

Don't need to document this. It is implied and could be in the parent.

Hello Rob, All

Sorry for long delay - I was ill for a few days. Back at the business
now =)

Rob, maybe dropping the RFC tag has messed your book keeping? This
is the latest version:
https://lore.kernel.org/lkml/90c3b820baf072a7cc3a21aa50c661774a045158.1550148989.git.matti.vaittinen@fi.rohmeurope.com/
and I thought it already had the Reviewed-by tag from you :)

I see at least the patch subject comment is still valid though. Do you
want me to change it and resubmit the series?

I thought I ignored RFC tag, but could be that. My script (and memory)
aren't perfect.

No, if that's the only thing, it's not important.

+BD70528MWV is an ultra-low Iq general purpose single-chip power management IC
+for battery-powered portable devices. The IC integrates 3 ultra-low current
+consumption buck converters, 3 LDOs and 2 LED Drivers. Also included are 4
+GPIOs, a real-time clock (RTC), a 32kHz clock gate, high-accuracy VREF
+for use with an external ADC, flexible dual-input power path, 10 bits SAR ADC
+for battery temperature monitor and 1S battery charger with scalable charge
+currents.
