Subject: [PATCH 1/2] dt-bindings: media: mediatek-jpeg-encoder: change max ioomus count

MT8186 has 4 iommus in the list, to cope with this situation, adjust
the maxItems to 4 (instead of previous 2).
Add also minItems as 1 since iommus are mandatory, to avoid warning
on the example.

Can we please call this jpeg-encoder@17030000 instead?

clock-names ...
iommus ....
power-domains ...

(commit title) `ioomus` is something I've never heard of before... :-P

Please fix the typo, after which:

maxItems alone means minItems is the same size. If IOMMU is required,
then 'required' is where that is defined. Is there a case where 1 IOMMU
is valid? If so, what h/w has this case.

Hello Rob,

Without setting a minItems , the example in the binding fails, because it has just
2 items, while the maxItems is now 4.
I set minItems as 1 to avoid restricting any kind of hardware to have at least 2
items, but if you claim that previously, maxItems=minItems=2 , I will change this to 2.
Is that fine with you ?

Eugen

I think that's what you should do yes. If in the future there shows up a
platform with just one iommu, then we can fix that.
