I'm unable to get any GPIO to work on any Avoton-based platform, including Mohon Peak, with the patches provided and applied to a kernel.

I see the following in dmesg:
(one message per GPIO)
gpio_request: gpio-52 (sysfs) status -22
export_store: status -22

the script returns the following:
testing GPIO pin 58 ...
/usr/bin/ line 6: echo: write error: Invalid argument

Steps to Reproduce

run the provided test script
