This depends on support in the pinctrl driver, which will be applied after the merge window to different tree or branches than DTS is going to. Therefore if I apply your DTS with "-gpio-bank" to my next/dt64, the kernel won't find GPIo banks and won't properly boot. The linux-next will be fine, just my next/dt64 won't be. If you're fine with it - use "-gpio-bank" suffix. If you prefer my next/dt64 to have a fully working Tesla SoC DTS, then stick to old node naming and let's replace it later. Best regards, Krzysztof

Which also means that my v2 will not be based on your new pinmux schema. Probably we will move to that after the merge window. >If you're fine with it - use "-gpio-bank" suffix.
