I used `compatible = "brcm,bcm43752-bt", "brcm,bcm43430a0-bt";` in my DT and Bluetooth works equally well. Both of these patches can be ignored, thanks for the review. There are multiple compatible with no match data, and I was mostly following that approach. Are they there mostly for legacy reasons and adding more with no match data is discouraged? Or am I missing something else? Thanks, -- Hugo
