Mark it as read-only as it is factory-programmed with identifying
information, and no executable nor configuration:
- eth MAC address
- board model (PCB version, BoM version)
- board serial number
Accidental modification would cause misidentification which could brick
the board, so marking read-only seem like both a safe and non-constraining
choice.

These sub-functions are available in the chip revision on this board, so
expose them.

This chip is handled by the existing pmbus module, and there is indeed no
matching entry in Documentation/devicetree/bindings/hwmon/pmbus. I am not
especially knowledgeable about this chip, I only know it is used by this
board, so I am not sure I can do the best job in putting such a file
together.
If needed I can git it a try.

Devicetree bindings are supposed to be stable into the future, so an actually
reviewed binding is quite necessary ;-) .
In the case of your tps544b20 it should also be pretty easy to do, as
Documentation/devicetree/bindings/hwmon/pmbus/ti,ucd90320.yaml
is probably a pretty good match to what you need in terms of Yaml notation.
Just need to replace the naming in your copy and drop in the correct
description from
https://www.ti.com/lit/ds/symlink/tps544b20.pdf?ts=1637055780278
and you have a working binding.
Then just add another patch to your series that mimics
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8a36e38d8b0fbb92609e837a67f919202ec7ec51
and include the relevant maintainers that scripts/get_maintainer.pl will
give you, and you're all set :-)

This should definitly be
compatible = "ti,tps544b20";
i.e. include the ti vendor-prefix. The i2c-core will automatically
remove this when matching against the i2c devices.

Hi Heiko,
In current form the bindings would be close to trivial and we actually
do not know how proper bindings would look like (the device is not
trivial). Therefore based on Rob's recent comments - better to have
trivial schema than nothing - I sent a patch adding them to trivial-devices:

Though I guess there isn't anything hindering additions to a individual
simpler binding.
But yeah, just adding it to trivial devices will also just work for now, as there
really are no additional properties right now and might make the process
a tad shorter ;-)

Node name should be a generic class of a device. This is a DC-DC

The existing values are rejected by the da9063 regulator driver, as they
are unachievable with the declared chip setup (non-merged vcore and bmem
are unable to provide the declared curent).
Fix voltages to match rev3 schematics, which also matches their boot-up
configuration within the chip's available precision.
Declare bcore1/bcore2 and bmem/bio as merged.
Set ldo09 and ldo10 as always-on as their consumers are not declared but
exist.
Drop ldo current limits as there is no current limit feature for these
regulators in the DA9063. Fixes warnings like:
DA9063_LDO3: Operation of current configuration missing

when sending a patch series with "git format-patch -6" and friends will
automcatically generate x/y additions like "[PATCH 1/6]" and so on.
Please try to keep them around when sending, as automated tools for patch
handling like "b4", stumble when they encounter a patch series without them.
In this case a
b4 am f6512cc50dc31a086e00ed59c63ea60d8c148fc4.1637023980.git.plr.vincent@gmail.com
[first patch in the series]
will actually only retrieve the last patch
"[PATCH] riscv: dts: sifive unmatched: Link the tmp451 with its power supply."
as it thinks it's a new version of the first one.
Thanks
Heiko

Actually my intent was to not make this a series, as in my understanding
independent patches should/may be submitted separately from each other.
They just happen to be stacked, and in this order, in my working copy,
but should not functionally have any dependency on one another (I
believe they should even apply cleanly in any order).
It is only after sending that I realised that
git send-email --no-thread [...] v5.16-rc1..riscv_for_upstream
still decided to thread the emails...
Which indeed makes my use of "--no-numbered" a mistake. Sorry for not
checking --dry-run output more closely.

This should be a series because the patches, even though independent,
are logically connected/grouped as one work.
