I'm not sure what you mean with that term: simply identifying that the device works using device specific code ? I've looked at several *_probe functions from other drivers and they are all completely different with no common code... Or do you mean calling of_platform_bus_probe() ? What does that function do ? > No it's just that platform_drivers are now able to do all the things an > of_platform_driver can do, so new code should just use platform_driver. > > I'm not sure if of_platform_bus_probe() will go away eventually, but for > now it is the only way to achieve what you need. I assume the kernel needs to be compiled with CONFIG_OF. ...hmm I had to "git pull" in order for this to compile your snippet. That's really recent! Unfortunately i need to reflash my device with the new kernel before i can begin testing my module. When I try to compile your (adapted) snippet, I got this minor problems: .probe = foo_driver_probe, ^ warning: initialization from incompatible pointer type Shouldn't foo_driver_probe be: static int foo_driver_probe(struct platform_device *pdev) instead of: static int foo_driver_probe(struct platform_device *device, const struct of_device_id *device_id) Also: struct foo_device *foo; That's where I put my own content, right ? And needs to be kfreed in a foo_driver_remove() function, right ? > > I still need a platform_device_register() after your sample init, right ? > > I had one in there already, in foo_driver_init(), didn't I? You had platform_driver_register(), not that I'm all clear yet on the distinction... Another question: I just spent 10 minutes trying to find where "struct device" was defined. (ack-)grep was absolutely no use. Isn't there a way to cross- reference my own kernel, the way I've compiled it ? -- Guillaume Dargaud http://www.gdargaud.net/Climbing/ _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
