Subject[PATCH v2 01/11] serial: sh-sci: Update DT binding documentation for GPIO modem lines
Date
Amend the DT bindings for the Renesas SCI driver to allow describing
optional GPIO-controlled modem lines, which can be used where dedicated
modem lines are not available.

The property naming is dictated by the Generic Serial DT Bindings.
