The current driver has some troubles:
- Some groupings are wrong.
- The pinctrl group0 owns pins never used (at least in Openwrt) for any
pinmux. The driver hijacks all the pins on the group avoiding any other
use, spite they're free. I.e. for buttons, causing this kernel error:
[ 4.735928] gpio-keys-polled keys: unable to claim gpio 479, err=-22
[ 4.742642] gpio-keys-polled: probe of keys failed with error -22
- Minor errors about groupings on the documentation
- Missing "diag" grouping in dtsi
- Wrong groupings in dtsi
Fix it by setting the correct groups.
And relax the pin capturing, letting the gpios belonging to any group to
be used for other purposes like buttons. This was the behavior with stock
firmwares and old OpenWrt versions which never caused any trouble.
