That is typically used when the wifi and bt has the *same* name, so the only way to distinguish between them is a suffix. Yours, Linus Walleij

Cypress support had later confirmed BCM4349B1 and BCM89359 to be the same chipset. I should probably rephrase the commit message. >> + - brcm,bcm4349-bt > > Then why do you have to tag on "-bt" on this compatible? > > That is typically used when the wifi and bt has the *same* name, so > the only way to distinguish between them is a suffix. I think that's the case here too. Cheers, Ahmad > > Yours, > Linus Walleij >
