Hey folks,

This is my first PR for 6.19, and it's a wee bit in advance of the
others just in case there's some objection that needs reworking.
Krzysztof is probably already aware of what's going on here, but I threw
the toys of the pram over the behaviour of the vendor here, and so
appointed myself maintainer after the submitter decided they were not
comfortable doing so any more. You can read the context here if you like:
https://lore.kernel.org/all/20250922-dr1v90-basic-dt-v2-0-64d28500cb37@pigmoral.tech/
I'm only there as Odd Fixes, and I hope that I can eventually hand this
over to someone who cares about it specifically.
I consider what's here to otherwise be a bit on the premature side, with
no clock, reset or pinctrl drivers, but the submitter of the initial support
is currently working on that and I figured sorting out the maintainer
thing made sending it at this point worthwhile.

Cheers,
Conor.

Initial Anlogic Platform Support

Add bindings for the serial and timer peripherals, and a basic soc dtsi
for the Anlogic dr1v90 SoC. The Milianke MLKPAI FS01 is the first board
for this SoC. Add myself as maintainer for this platform for the time
being.
