We achieved consensus allowing sa8775p to stay, but now Qualcomm changes point of view and insists on new approach of dropping sa8775p. Therefore this change does not make much sense in the new approach. Best regards, Krzysztof

As I understand the that Qualcomm will support both SA8775p and QCS9100 in Kernel. There’s no plan to drop SA8775p support. These two SoCs will keep compatible. > Best regards, > Krzysztof > -- Thanks & Regards, Taniya Das.
