Subject: Determining wich PWM to use
Date: Sat, 27 Jul 2013 12:18:24 +0200	[thread overview]
Message-ID: <20130727101824.GA11956@sauron.fritz.box> (raw)

Hi list,

I'm currently working on a pwm driver for the BCM2853 (the SoC used on the
RaspberryPi). It has two PWM modules, so my question is, how do I determine
which PWM to use in the .enable, .disable and .configure functions?

If someone wants to have have a look at the preliminary code (far from being
submittable and only compile tested) it can be found here:

https://github.com/morbidrsa/linux/blob/rpi-pwm/drivers/pwm/pwm-bcm2835.c

2nd short question, is it considered good practice to encapsulate registers in
structs? I've seen this a lot on powerpc code.

Thanks for your help.

Johannes
