Hello Greg and all, Thus wrote Greg KH (greg@xxxxxxxxx): > Please do not do that. There are valid kernel apis to grant access to > registers easily, the most simple case would be a "reset reason" register within the chip's address space. A hand-crafted driver would ioremap the region and implement a sysfs show method that reads the register. What do you recommend for providing read access to such a register via sysfs? Is this a job for the userspace I/O (UIO) subsystem?
