Hello

Yes, my way is an error.
Next time, I will split my patch in 2, first a 1 to 1 conversion, then a binding update.

I have create a binding update patch (https://github.com/montjoie/linux/commit/da05ef9bb488c16cfd15a47054f5b1161829b6bf)
But I have lot of problem, DT are not validating.
Example: Documentation/devicetree/bindings/crypto/rockchip,rk3288-crypto.example.dtb: crypto@ff8a0000: resets: [[4294967295, 174]] is too short

I have tried also to set default resets/maxItems to 3 and setting it to 4 via an if. But I still got error like maxItems cannot be update after initial set.

Any idea on why my new binding update patch is failling ?

Regards
