up square support for kernel 4.4.x
Any member of dev team here? where can i get the driver to support gpio in kernel 4.4.x?
right now i can't export any pin win the gpio..
echo 27 > /sys/class/gpio/export
-bash: echo: write error: Invalid argument
Although i can communicate with gpio hat S.USV UP using i2c...
i suspect that could be because of missing drivers/platform/x86/up_board.c that is available for linux kernel 4.9.x. but i can't use this kernel because there is an issue with network encapsulated traffic and vpns.
Thanks for the help.
