 Yeah, I guess especially how it could be merged with the cw1200
 driver
 would be very relevant to that commit log.

As I haven't seen any consensus that applying bindings document for
out-of-tree drivers is ok so at least I'm not taking this. Though not
sure what DT maintainers are planning to do.

The question is whether we should. The above might be a precedent,

but it

may not necessarily be the way to go. The commit message for esp8089

seems

to hint that there is intent to have an in-tree driver:

"""

this

hardware, there is no clear timeline / path for merging this.

Still

I believe it would be good to specify the binding for this in

tree

now, so that any future migration to an in tree driver will not

cause

compatiblity issues.

The cw1200 driver seems to still have some legacy platform
data. Maybe they should also be convert to DT.
(Or maybe compatible = "allwinner,xr819" is enough, as
xr819 is a specified variant of cw1200 family)


Ah, so the upstream cw1200 driver supports xr819? Has anyone tested
that? Or does cw1200 more changes than just adding the DT support?


The support of XR819 in CW1200 driver is far more difficult than I
imagined -- the codedrop used in the mainlined CW1200 driver seems to
be so old that it's before XR819 (which seems to be based on CW1160),
and there's a large number of problems to adapt it to a modern CW1200
variant.

P.S. could you apply this device tree binding patch now?

The question is whether we should. The above might be a precedent,

but it

may not necessarily be the way to go. The commit message for esp8089

seems

to hint that there is intent to have an in-tree driver:

"""

The cw1200 driver seems to still have some legacy platform
data. Maybe they should also be convert to DT.
(Or maybe compatible = "allwinner,xr819" is enough, as
xr819 is a specified variant of cw1200 family)


Ah, so the upstream cw1200 driver supports xr819? Has anyone tested
that? Or does cw1200 more changes than just adding the DT support?


By doing some tests, XR819 is in the the CW1x60 family, which is not
yet well supported by cw1200 driver.

More work should be needed for support xr819 in cw1200 driver.

I think the cw1200 driver currently lacks maintain, and
the product is already discontinued by ST-E.

See esp8089.

There's also no in-tree driver for it.
