The CS needs to be raised between each byte read/written. And as it was put independently by two people, we should really know the real issue on the wire with this. And if it's as described, try to find an existing example in the kernel that uses a similar approach. I think regmap SPI should have such a feature. > Therefore using u8 gain[2] here and in other places will be just an extra populated > array since regmap_read requires `unsigned int` as input. The problem here is open coded endianess conversion. -- With Best Regards, Andy Shevchenko
