Hi Uwe, Daniel, and Thomas,

Just a gentle reminder on this series. This patch series has received 
Reviewed-by and Acked-by tags from Krzysztof on the bindings portion. 
For the driver part, I have already responded to Sashiko's review 
comments and provided explanations.

Could you please help review the remaining patches? I would appreciate 
any further feedback or suggestions on how to proceed with this series.

Thanks for your time and attention.

Best regards,
Xuyang Dong
