The indentation here is off, but I noticed that you've probably just
copied that from the existing devicetree sources. I just sent a couple
of patches to clean that up:

	https://lore.kernel.org/lkml/20221116102054.4673-1-johan+linaro@kernel.org/

You can drop the first newline and indent the continuation line properly
using tabs (and spaces).
