Both here in this example, and ...

Here in the actual .dts file, you should include the specific ID of the
SoC too, so that if there are Soc-specific bugs, the compatible property
that's required to determine this is present from the start. In other words,

compatible = "bcm,bcm11351-smc", "bcm,kona-smc";

(which SoC ID you use in the example is arbitrary, but it may as well
match the .dts file you're editing in the patch).
