Add back `GPIOMEM` #227

Closed jjcarstens closed 8 months ago

jjcarstens commented 8 months ago

/dev/gpiomem was being used by other libraries for non-root memory access of GPIO (such as :dht). In a previous commit, this was removed as part of a different cleanup and these libs are now failing (see 62e0d10)

This adds back CONFIG_RASPBERRYPI_GPIOMEM which is also enabled for all the other raspberry pi systems

See this forum post for more info

Did you check the other 64bit Raspberry Pi's?

jjcarstens commented 8 months ago

I checked rpi3, rpi3a, and rpi5 which have this config set. Looks like I may need to enable for rpi0 and rpi0_2

Thanks! I added the patch to rpi0 and rpi0_2.
