Okay. Are PHYs _always_ platform devices?

They can be i2c, spi or any other device types as well.
In those other cases, presumably there is no platform data associated with the PHY since it isn't a platform device. Then how does the kernel know which controller is attached to the PHY? Is this spelled out in platform data associated with the PHY's i2c/spi/whatever parent?
Platform data is nothing to do with the platform bus - it's board specific data (ie, data for the platform) and can be done with any device. -------------- next part -------------- A non-text attachment was scrubbed...
