Actually I need to correct myself here. While the programming sequence description is the same as on i.MX6, the register layout looks like the i.MX7 one, so likely someone copy and pasted the wrong documentation snippet. This means the controller is in fact compatible to the i.MX7 write sequence. > Also the number of fuses is different, so we really need some driver > support for the imx8mq compatible and can't declare the controller > compatible to some older instance. But then I think this is still true. The changed number of fuses means we need some driver support and should not claim backward compatibility with the i.MX7 controller. regards, Lucas
