A10 lime fast GPIO
« on: October 03, 2014, 09:59:16 PM »

I was wondering if there is a way of controlling the lime GPIO without sysfs.
There was the same conversation for the allwinner A13

Although there seem to be multiple ways to do it. There is no one of them clear enough.
In the u-boot sources there is Tom drivers for gpio

I am lost with the multiple choices i have to make.
Any kind of help appreciated!

Those ways should work but if you're struggling to cope with them then I suggest sticking to Linux own way (via FS).

Bear in mind that Linux can suddenly reschedule and leave your app not running for an unpredictable, sometimes long, time.
