The /schemas/serial.yaml from dt-schema only has the property $nodename, whereas the kernel-defined /schemas/serial/serial.yaml contains more useful properties, support for more complex application scenarios. For example: 1) The property "current-speed" in fsl-lx2160a.dtsi 2) The subnode "bluetooth" in hi3660-hikey960.dts Reviewed-by: Rob Herring <robh@kernel.org> Signed-off-by: Zhen Lei <thunder.leizhen@huawei.com> Link: https://lore.kernel.org/r/20210506132049.1513-2-thunder.leizhen@huawei.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
