Re: PCIATA driver matching

I see where you're going with this. Basically that's how the CMD646 driver works. However, I notice it tries to match on a 'ata-4' property, and for the life of me I can't seem to find where you set that property on the Root driver.

Thanks for the heads up.

Ernesto.


Hi Ernesto,

The 'ata-4' property is in the device tree in the boot-rom. We just copy down what the boot-rom left in the device tree when creating the nub.

If you are rolling your own driver for something that doesn't have an openfirmware ROM on it, you'll just insert whatever information you need for your device to work. Basically, just make a name, say "ernesto-corvi-ata" for example and add that to the dictionary for the nub. You can also insert the device memory properties, whether this is the primary or secondary ATA cell in the chip or whatever makes life easier for you in the ATA part of the driver.
