How does PWM work, how many pins support PWM on A20?
kivutar, hm, I am able to boot with systemd 210 - gmac wasn't really working for updating (making it built-in rather than module helps, but still wrong mac and got systemd errors trying to restart network)

these issues appears starting from systemd 213 anyway

speakman: I guess abelloni might be able to help you understanding how PWMs work on A20 (he submitted a driver to support these PWMs in mainline)
bbrezillon: Thanks, but it looks like there is only two PWM channels (and hence only two PWM-enabled pins) and that's not enough for me anyway. :/
On the other hand; do any of you know if A20 GPIO can be set to Open Drain?
this one's a null derefence, but I've seen illegal instruction oopses and other symptoms that make me think some form of memory corruption is going on

Hi, clould someone please help me? Having some issue with porting i2c driver to a13 platform for linux 3.0.15. Driver is loaded as module, _init() function is being called but _probe funcion does not. Usually there is some board file where you can register devices by hand, but I can not find this file for a13 platform, what is the proper way of adding new i2c device?
