5   The Infineon XMC4XXX pin controller is responsible for connecting peripheral outputs
8   The pinctrl settings are referenced in a device tree peripheral node. For example in a UART
12       compatible = "infineon,xmc4xxx-uart";
13       pinctrl-0 = <&uart_tx_p0_1_u1c1 &uart_rx_p0_0_u1c1>;
14       pinctrl-names = "default";
15       input-src = "DX0D";
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
21   to help the user select the correct pin settings. Note the use of peripheral type,
22   pin direction, port/pin number and USIC in the name.
24   The pre-defined nodes only set the alternate function of the output pin. The
25   configuration for the pin (i.e. drive strength) should be set in the board setup.
26   The set of possible configurations are defined in the properties section below (in addition
27   to the inherited property-allowlist list from pincfg-node.yaml).
31   #include <zephyr/dt-bindings/pinctrl/xmc4xxx-pinctrl.h>
35       drive-push-pull;
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

77         Alternate function is only set for output pins; It selects  ALT1-ALT4
78         output line in the GPIO element. The alternate function for input pins is
79         handled separately by the peripheral. It is upto the peripheral to configure which
80         input pin to use (For example see parameter input-src in infineon,xmc4xxx-uart.yaml).
84     drive-strength:
86         Drive strength of the output pin. Following options as in XMC_GPIO_OUTPUT_STRENGTH
87         See xmc4_gpio.h. This only has an effect if the pin is in drive-push-pull mode.
