Hi Shine,

Regarding the ISP, the only limit is that the line width must be smaller than 4096.

About SPI DMA, I'll ask the SPI expert answer your question.

Hi Jianzhong,

Thank you very much for your great support.

Customer wants to know if there is special requirement for width/height in Linux driver? Some chip manufacturers may require a minimum width for specific software implementations, or may require that the width and height be an integer multiple of a certain value (e.g. 32).

Thanks
