/* Create a pincfg device tree node:
 *
 * The node name and nodelabel will be of the form:
 *
 * NODE = p<port>_<pin>_<inst>_<signal>
 *
 * NODE: NODE {
 *	cypress,pins = < &gpio_prt<port> <pin> HSIOM_SEL_<hsiom> >;
 *	flags_1;
 *	  ...
 *	flags_N;
 * }
 *
 * So for example:
 *
 * DT_CYPRESS_PIN(uart5, rx, 5, 0, act_6);
 *
 * Will become:
 *
 * p5_0_uart5_rx: p5_0_uart5_rx {
 *    cypress,pins = <&gpio_prt5 0x0 0x12 >;
 * }
 *
 * Flags are optional and should be pass one by one as arguments:
 *
 * DT_CYPRESS_PIN(uart5, rx, 5, 0, act_6, bias-pull-up, input-enable);
 *
 * Will become:
 *
 * p5_0_uart5_rx: p5_0_uart5_rx {
 *    cypress,pins = <&gpio_prt5 0x0 0x12 >;
 *    bias-pull-up;
 *    input-enable;
 * }
 *
 * For the complete list of flags see cypress,psoc6-pinctrl.yaml
