The GPIO controller from the modem does not have an interrupt. Acked-by: Conor Dooley <conor.dooley@microchip.com> Signed-off-by: Dang Huynh <redacted>
If the GPIO controllers are so different, should they not have different compatible strings? Maybe add rda,8810pl-modem-gpio compatible for the modem GPIO then? +++ b/Documentation/devicetree/bindings/gpio/gpio-rda.yaml

Then this can be conditional using an if:-statement such that it is only mandatory for rda,8810pl-gpio and not for rda,8810pl-modem-gpio. Yours, Linus Walleij
