Expand description

@brief Combine a GPIO input with a peripheral signal, which tagged as input attribute.

@note There’s no limitation on the number of signals that a GPIO can combine with.

@param gpio_num GPIO number, especially, GPIO_MATRIX_CONST_ZERO_INPUT means connect logic 0 to signal GPIO_MATRIX_CONST_ONE_INPUT means connect logic 1 to signal @param signal_idx Peripheral signal index (tagged as input attribute) @param inv Whether the GPIO input to be inverted or not
