19   pinctrl-0 is the phandle that stores the pin settings for two pins: &uart_tx_p0_1_u1c1
20   and &uart_rx_p0_0_u1c1. These nodes are pre-defined and their naming convention is designed
22   pin direction, port/pin number and USIC in the name.

38   where XMC4XXX_PINMUX_SET(PORT, PIN, ALTERNATE_FUNCTION) is a helper macro for setting the
39   alternate function for a given port/pin. Setting ALTERNATE_FUNCTION = 0 means that no
40   alternate function is selected.
42   The pinctrl driver only sets the alternate function for output pins. The input mux is
43   handled by the peripheral drivers. For example the &usic1ch1 node has input-src property for
44   this purpose. There are no pre-defined nodes for the input mux and this must be properly set
45   by the user. Refer to the peripheral .yaml file (i.e. infineon,xmc4xxx-uart.yaml) and
