v4:
 * Remove older bindings [Matthias/Krzysztof]
 * Misc. Fixes [Krzysztof]
 * Rebased on v2 of Krzysztof's bindings cleanups

v3:
 * Re-ordered clock list, fixed pdc_sync typo [Rob/Matthias]

Instead of maxItems can this be

       items:
         - description: Name of MBA firmware
	 - description: Name of modem firmware

so that we know the order? Same for 'memory-region' above.

Should this have maxItems: 1? Or that's implicit from description?

Should this have min/maxItems: 2?

This one did items for a phandle array so I think we should follow the
same above.

Because it's two items I'd expect:
	
	<&tcsr 0x10000 0x10004>, <&tcsr_mutex 0x26004 0x26008>;

I guess both the ways work since the driver uses
of_parse_phandle_with_fixed_args.

See commit 39bd2b6a3783 ("dt-bindings: Improve phandle-array schemas")
for why the way you have it is not preferred.

I am not aware of such implicit rule in schema. maxItems are always
required. If this is maxItems:1 it is not even an array.

You should also define the items. This applies to all such fields. Check
the examples of syscon consumers.

But only one is correct...
