- Subject: dt-bindings: net: dsa: qca8k: Document qca,led-open-drain binding
- Document new binding qca,ignore-power-on-sel used to ignore
- power on strapping and use sw regs instead.
- Document qca,led-open.drain to set led to open drain mode, the
- qca,ignore-power-on-sel is mandatory with this enabled or an error will
- be reported.
