My $0.02 on thinkpad_acpi & HID's... 1. moving to DMI binding from PNP-id binding sounds like a step in the wrong direction. Are there thinkpads that you need to support that don't export IBM0068? There is a long tradition of DMI information being copy/pasted and being invalid. While the thinkpad BIOS guys are probably above average here, they're probably not immune from this issue. At the end of the day, I'd be astonished if somebody told me that the Windows thinkpad platform driver binds via DMI strings instead of binding to IBM0068 -- which was likely invented for this sole purpose. 2. IBM_PCI_HID = ACPI_PCI_HOST_HID = PCI_ROOT_HID_STRING = "PNP0A03" There is nothing IBM specific about a PCI root bridge. If you need to use this one, please call it PCI_ROOT_HID_STRING. thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
