According to the AW88261 datasheet (V1.1) and device schematics I have access to, there is no reset gpio present on the AW88261. Remove it.
That looks to be the case according to

Nice to see the doc is also available there. Seems it only shows up on the site search but not with Google
https://www.awinic.com/en/search/all?titleSearch=AW88261
(which is v1.5 FWIW), Weidong?
In case this looks okay, also to the driver author at Awinic, the binding doc also needs to be updated to include this change and not require (or even allow) the reset-gpios anymore.
It would be easier to just send the proper patch to start off with, no need to resend if the change is confirmed...
Unfortunately the dt binding is a bit trickier to update since it's made for both AW88261 and AW88395.
After spending a bit of time using non-Google search machines (Google seems incapable of finding anything there) I found a datasheet for AW88395 and that does appear to have a RSTN "Active low hardware reset" pin so we should not remove that one.
Probably it's easier to separate the two dt bindings then, instead of trying to keep them together?
