pinctrl: uniphier: add UART hardware flow control pin-mux settings
Browse files Browse the repository at this point in the history 
UniPhier SoCs have the following pins for hardware flow control of UART:
  XRTS, XCTS
and for modem control of UART:
  XDTR, XDSR, XDCD, XRI

The port number with the flow control is SoC-dependent.
