I want to control brushless fan. I used gpio-pwm modules to control it but found it was not stable. I also have concern about it's performance issue of software PWM.

So does the soc support hardware PWM?

You won't find and documentation. Broadcom is very protective. You won't even be able to find pinouts of the SOC.

At most, you will find a block diagram that is more for advertising then it is technical.
