Hi Arnd,

thanks for looking into this!

This looks like something that would be interesting to pick up and maintain
with DT support, if and only if there are devices with enough memory.

However I doubt there is interest.

I think the palmtops/PDAs are a bit outdated as enthusiast/hobbyist platforms
with screens because those people will use PostmarketOS with
cheap old tablets and phones these days.

My interest is to have something to test that CPU_SA1100 is working
on and I've been using the HP3600.

If I wanna keep doing that I should bite the bullet and convert it to
DT and multiplatform like I did with everything else I need for testing.
Else I deserve to have it removed on me and I can resurrect it
using DT if I want.

I'm using the NetWinder to test that CPU_SA110 is still working.

Same thing: if it matters enough to me I should convert it to DT
and multiplatform.

Someone said (ha ha only serious) to convert it to ACPI if it should
live on since it is a desktop machine...

TI is semi-actively maintaining DaVinci, I wonder if we can send
the message that this needs to be converted to DT pronto to live
on?

Paging Aswath @TI, who just a few days ago sent some
suspend/resume patches for GPIO:
https://lore.kernel.org/linux-gpio/20220613054310.21186-1-a-govindraju@ti.com/

Aswath: can you perhaps raise this internally at TI? Thanks!

Patches also came from Nokia (!) last year see
