The Synopsys DesignWare ABP UART is commonly used. Therefore, it is meaningful to clear the warnings detected by snps-dw-apb-uart.yaml. I fixed everything I could. The only problem left is that some serial port nodes do not have the property 'interrupts'. I don't know their interrupt number, so there's no way to fix it. By the way, is there a scenario where serial ports do not need to be interrupted? If it exists, property 'interrupts' should not be defined as required.
