ROHM BD71828 Power management IC integrates 7 buck converters, 7 LDOs,
a real-time clock (RTC), 3 GPO/regulator control pins, HALL input
and a 32.768 kHz clock gate.

Document the dt bindings drivers are using.

Don't list me or Mark here. I maintain everything...

How many?

Standard units need a unit suffix as defined in property-units.txt. So 
'-ohms' in this case. With that, you can drop $ref because we already 
define the type.

Is there a valid range of values? If so, use minimum/maximum.

Not bisectable. These files have to come in this patch or before.

Filename should match the compatible if possible.

Need to document what the name is. Though, with only 1 clock, not that 
useful.

How many? Needs 'maxItems'.

'make dt_binding_check' reports an error building this, but I'm not 
seeing where it is:

Linus Walleij already notified me about this. I just wondered why this
is not reflected in:

LICENSES/preferred/GPL-2.0

which seems to state:

I'll change the SPDX for new files for next version.

Ok. So I'll add myself then. Although I am by no means an expert what
comes to binding schemas. I know the device and driver though.

Hmmm. I thought this would depend on rest of the system's DT. Why
should it be same on each board? (I can drop this out though).

I guess it is the LED function definition. Those function/colour
bindings were only added in 5.4-rc1. Do you have them defined in your
build environment at /include/dt-bindings/leds/common.h?

Rest of the comments are clear to me :)

+description: |
+  BD71828GW is a single-chip power management IC for battery-powered portable
+  devices. The IC integrates 7 buck converters, 7 LDOs, and a 1500 mA
+  single-cell linear charger. Also included is a Coulomb counter, a real-time
+  clock (RTC), and a 32.768 kHz clock gate.
+
+  The BD71828 RUN state is divided into 4 configurable run-levels named RUN0,
+  RUN1, RUN2 and RUN3. Bucks 1, 2, 6 and 7 can be either controlled individually
+  via I2C, or some/all of them can be bound to run-levels and controlled as a
+  group. If bucks are controlled individually these run-levels are ignored. See
+  ../regulator/rohm,bd71828-regulator.yaml for how to define regulator voltages
+  for run-levels. Run-levels can be changed by I2C or GPIO depending on PMIC's
+  OTP configuration.
