It is not very common to add oneself as the maintainer of a single .dts
file. I could only found the am335x-nano.dts with such a way of doing.
Usually get_maintainer.pl will also take into account the commit author
and properly handle this case.

For all the boards that I have seen, all the properties of a new node
are declared at the same place, where you put some of them at the end. I
have not a strong opinion on this, but I find it a bit more difficult to
read.

Splitting the pinmux is also unusual, but in this case I found it more
readable.

The INT pin of the LIS33 chip seems to be push-pull, thus enabling the
pullup on the SoC side will increase the current consumption when held down.

You already have an external pullup in your design, so this one seems
superfluous.

Why are all the regulators always on? Most of them should be managed
automatically if you have correct dependencies, shouldn't they?

You can use the key codes defined in <dt-bindings/input/input.h>.

Why enabling the pulldown on an output gpio? You will increase the power
consumption when driving high.

It is not very common to add oneself as the maintainer of a single .dts
file. I could only found the am335x-nano.dts with such a way of doing.
Usually get_maintainer.pl will also take into account the commit author
and properly handle this case.

For all the boards that I have seen, all the properties of a new node
are declared at the same place, where you put some of them at the end. I
have not a strong opinion on this, but I find it a bit more difficult to
read.

Splitting the pinmux is also unusual, but in this case I found it more
readable.

The INT pin of the LIS33 chip seems to be push-pull, thus enabling the
pullup on the SoC side will increase the current consumption when held down.

You already have an external pullup in your design, so this one seems
superfluous.

Why are all the regulators always on? Most of them should be managed
automatically if you have correct dependencies, shouldn't they?

Why enabling the pulldown on an output gpio? You will increase the power
consumption when driving high.

Okay--I'll remove this. Ironically, I was looking at the nano to make
sure I'd done everything I needed to ;-).

My goal both by moving the properties and the pinmux was to separate
out chunks of functionality into discrete sections. It makes it easy
to resolve an issue with a specific board feature (e.g. LEDs) or adapt
for a new board version as the pinmux and any node properties are
grouped together.
I recognize this is something of a personal bias though so I can
certainly re-organize if this is stylistically bad.

Good catch.

These work fine as simple outputs.
Thanks for your careful review Florian. Much appreciated.

Okay--I'll remove this. Ironically, I was looking at the nano to make
sure I'd done everything I needed to ;-).

My goal both by moving the properties and the pinmux was to separate
out chunks of functionality into discrete sections. It makes it easy
to resolve an issue with a specific board feature (e.g. LEDs) or adapt
for a new board version as the pinmux and any node properties are
grouped together.
I recognize this is something of a personal bias though so I can
certainly re-organize if this is stylistically bad.
