So the unexpected abnormality here is that even though this device is instantiated by dt, the driver doesn't provide any compatibles. Either my expectation is wrong, then 67d02a1bbb33455 should be revertedYour expectation is wrong. AMBA primecell devices have hardware IDs and are matched to their drivers by those IDs. Just like PCI.pci devices don't appear in dt, do they? I don't see the connection between amba devices and platform devices, see my other mail in this thread for some more details.
They both have hardware IDs, and they are both matched via those hardware IDs. Your change has introduced a regression and is therefore wrong. -- RMK's Patch system: http://www.arm.linux.org.uk/developer/patches/ FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net.
