I actually added this dependency deliberative. It's true that the driver is using the device properties API and so there isn't anything from the properties parsing point of view that depends on OF. And the original driver didn't depend on OF.
But the original driver also only would had worked with Device Trees since the of_device_id table is the only one that contains the device specific data info.
The i2c_device_id table only listed the devices supported to match, but then it would only had worked with the default values that are set by the driver.
So in practice it *does* depend on OF. I'll be happy to drop that dependency if you provide an acpi_device_id table to match.
The code is deceptive and you become to a wrong conclusion. No, the driver does NOT depend on OF as a matter of fact. The tricky part is the PRP0001 ACPI PNP ID that allows to reuse it on ACPI-based platforms.
That said, please drop OF dependency.
