Okay I
- dropped device_type except for cpu & pci. I have the compatible string
for pci so I can drop the device_type once it is possible
- I lowercased all compatible types. I will need to resend some patches
which have upper case intel
- The cpu had the same compatible string as the soc node. So I added to
the soc node -immr for internel memory mapped registers.
- I added generic names for all parts.
- I reworked the i2c bars matching the way you suggested. I added a
compatible node for the PCI device which only the PCI ids in its
compatible string. The bars (each represents a complete i2c
controller) have a "intel,ce4100-i2c-controller" compatible node. It
is not used by the driver.
The driver is probed via PCI ids (by the pci subsystem not OF) and
matches the bar address against the ressource in the child node. Once
there is a hit the node is attached.
- The SPI driver is also probed via pci. However I also attached a
compatible property based on PCI ids :)
