Subject: RE: [PATCH v4 0/6] Add support for the Axis ARTPEC-8 SoC

Hi Krzysztof,

The dt-bindings patch was merged earlier in v3 series (https://lore.kernel.org/linux-samsung-soc/175664688891.195158.13270877080433356384.b4-ty@linaro.org/ on 31st August)
into respective maintainer repo. 
Then I have been asked to drop the applied v3 patches and send rebased v4 series (https://lore.kernel.org/linux-samsung-soc/15508cb4-843c-42d1-8854-5eabd79ca0df@kernel.org/)

Since the 4 patches from v3 series has been already merged, I have not the mentioned dependency while sending remaining v4 patches considering
It is going to same maintainer repo and it will be applied in sequence.

For future patches (like artpec-9), I will mention the dependency even it is merged in same repo.

Thanks,
Ravi
