Consider if they are expected or the schema is incorrect. These may not be new warnings. Note that it is not yet a requirement to have 0 warnings for dtbs_check. This will change in the future.

If you need external reference, then it should be some stable tag. But anyway if this is in mainline (is this?) then, why referencing via external link?

I just pointed to linux-next since that was what I had open at the time. Just to make sure if I understood correctly, if it's in mainline then there's no need to reference it via link? Or should I point to some tag instead, e.g.: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/i2c/busses/i2c-bcm-kona.c?h=v6.3#n731 Thank you for the review, Stanislav > > > Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> > > Best regards, > Krzysztof >

So, this depends on patch 1 but I2C doesn't pick up DT changes. So, shall this go via arm-soc, then? Or DT? Anyway, for any route: Acked-by: Wolfram Sang <wsa@kernel.org>

They do not affect bisectability. Please grab this patch via I2C. The DTS will go separately via arm-soc. Best regards, Krzysztof

Add BCM23550-specific compatible for brcm,kona-i2c nodes. While not currently used by the i2c-bcm-kona driver, they can serve for further customization, if required. Done in preparation for dt-binding coversion to DT schema.
