[PATCH v3 01/11] serial: sh-sci: Update DT binding documentation for GPIO modem lines

[Geert Uytterhoeven]

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.

[PATCH v3 02/11] serial: sh-sci: Update DT binding documentation for dedicated RTS/CTS

[Geert Uytterhoeven]

Some Renesas SCIF UARTs have dedicated lines for RTS/CTS hardware flow
control.  Whether these lines exist depends on SoC and UART instance
inside the SoC.  Whether these lines can be used for hardware flow
control depends on board wiring.

Amend the DT bindings with an optional property to indicate that RTS/CTS
hardware flow control lines exist, and can be used as such, according to
the Generic Serial DT Bindings.
