Re: [PATCH 0/6] arm64: qcom: Enable additional hardware on Radxa Dragon Q6A

Hi Xilin,

Thank you for the response.

I appreciate the offer to take over your patch set to move things 
forward. However, I feel I must respectfully decline. This is mainly due 
to my lack of experience with both upstream kernel development on this 
hardware and the patch management process itself. It would be 
irresponsible of me to take on something that I'm not knowledgeable 
enough to ensure successful completion.

I'm happy to work with you to help in any other way that I can such as 
testing patches, but I think you should maintain ownership of the 
patch-set and submission process, at least for now.

One of the reasons I withdrew my own patch-set is that from what I can 
see your series covers everything I was trying to achieve, and does it 
correctly :-)

The only one that isn't covered is the patch for early TCS 
initialisation that I'm discussing with Konrad which may be unnecessary 
anyway.
