Delta TN4810M uses a similar CPLD GPIO expander
like the TN48M, but it has pins for 48 SFP+ ports,
making a total of 192 pins.
It also provides the TX fault pins which the TN48M
does not.
Only TX disable pins like on the TN48M are output
ones.
Thankfully, regmap GPIO allows for the driver to be
easily extended to support the TN4810M.
Note that this patch depends on the following series:

Delta TN4810M expands the existing TN48M drivers, so lets
document the new compatibles.

This looks good to me. I suppose the other patches are going in
through the MFD tree. I don't see anything that can fail here at
build-time - can you confirm that I can pick these patches up
separately for v5.15?

Scratch that, I now saw Linus' comment about the special purpose pins
under the other series. Let's clear that up first.

Yeah,
I have finally replied to Linus,
hopefully, we can clear it up.

Hi Bartosz,
The TN48M path series that this depends on got stuck, and I haven't
received a reply in a while.
GPIO driver was initially reviewed and ACK-ed but then Linus W.
requested further information to see if this
truly fits as a GPIO driver, but then the discussion died a month ago.
You can see the whole discussion here:
https://patchwork.ozlabs.org/project/linux-gpio/patch/[email protected]/
I have multiple devices in the queue with a similar approach, so until
that one gets merged it makes no sense
to send stuff upstream.
I was hoping that we would reach some kind of a middle ground a long time ago.
Regards,
Robert
