Two simple patches for the Mediatek SCP dt-binding. The first fixes the
reg/reg-names property while the second adds a new optional
memory-region property.

The SCP has three memory regions: sram, l1tcm and cfg. Only sram is
required, the other two are optional. Fix the dt-binding so that the
optional regions can be omitted and passed in any order.

Also add the missing minItems to the reg property and update the
description.

The SCP co-processor can optionally be passed a reserved memory region
to use. Add this property in the dt-binding.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. 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.

memory-region has a type already, so drop. What's needed is how many 
entries and what they are if more than 1.

Hi Rob,

These indeed aren't new warnings. But in any case, the fix for the interrupts
one is already on its way to mainline [1]. And the memory-region one is what is
fixed by patch 2 in this series.

Thanks,
Nícolas

Hi Rob,

OK, didn't notice this common property was already documented elsewhere. In that
case I'll also drop the description since it's only 1.

Thanks,

No, cannot be passed in any order.

This allows them in any combination which is not what we want. If both
are optional and both can appear, then last should be a const:l1tcm.

Nicolas, I think that you weren't clear about what you're trying to solve with this
commit in the description.

I remember you had this kind of instance, but I don't really remember if it was
about mtk,scp or (and?) something else.... so.... are you trying to fix issues
with devicetrees declaring

	reg-names = "sram", "l1tcm"; ?

Was this giving dtbs_check errors?

Cheers,
Angelo

Hi Krzysztof,

yes, that's the case. I'll update it in v3 then.

Thanks,

Hi Angelo,

yes, some devicetrees (like mt8183) have

 	reg-names = "sram", "cfg";

I'll include mention of this in the commit description for v3.

This was also supposed to fix the warning for mt8192, where the order is
different: "sram", "l1tcm", "cfg". But since Krzysztof said that we want a fixed
order, then the mt8192 DT will need to be updated. (I also just noticed that
it's just l1tcm that is optional, I was just being blind, so I'll also fix that
in v3)

Thanks,
Nícolas
