Because it contains "arm,pl011", so the corresponding device tree nodes are also checked by this YAML file. As a result, many flase warnings similar to the following are reported: arch/arm64/boot/dts/freescale/fsl-lx2160a-clearfog-cx.dt.yaml: serial@21c0000: compatible:0: 'arm,pl011' was expected serial@21c0000: compatible:1: 'arm,primecell' was expected Change to only check the device tree nodes that are matched exactly.
