![]() In many SoC implementations there are hardware registers can be read or write only. This extends the debugfs to enforce the file permissions for these types of registers by providing a set of fops which are read or write only. This assumes that the kernel developer knows more about the hardware than the user (even root users) -- which is normally true.
