I believe the only way is to remove them from the main device tree overlay
since that will be loaded before anything else you can do. Decompile the

Hi Brandon,
I'm currently using mmap (in Python) to achieve register wide GPIO. I'm
concerned though, that the kernel still thinks it owns that memory and
might inadvertently write to it (for ex: if you forget to disable the
heartbeat trigger). Do you know of a way to disable the sysfs inter
That's still one bit control. There's going to be some unknown time between
the bits that will depend on cpu usage. For true 8 bit, you need to use
mmap to get a pointer to the gpio control block and modify the registers
directly.
Each gpio block has 32 pins, and each gpio block has a set and c
