You will probably need to upgrade to the latest kernel (or wait for the next raspbian release) if you're missing /dev/gpiomem. You will also need to add a `gpio` group, add your user to the group, and then set up udev rules. I would recommend using [create_gpio_user_permissions.py](https://github.com/waveform80/rpi-gpio/blob/master/create_gpio_user_permissions.py) if you're unsure how to do this.

PWM modes will still require root.
