[PARISC] Convert parisc_device tree to use struct device klists
Fix parse_tree_node. much more needs to be done to fix this file. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> Make drivers.c compile based on a patch from Pat Mochel. From: Patrick Mochel <mochel@digitalimplant.org> Signed-off-by: Kyle McMartin <kyle@parisc-linux.org> Fix drivers.c to create new device tree nodes when no match is found. Signed-off-by: Richard Hirst <rhirst@parisc-linux.org> Do a proper depth-first search returning parents before children, using the new klist infrastructure. Signed-off-by: Richard Hirst <rhirst@parisc-linux.org> Fixed parisc_device traversal so that pdc_stable works again Fixed check_dev so it doesn't dereference a parisc_device until it has verified the bus type Signed-off-by: Randolph Chung <tausq@parisc-linux.org> Convert pa_dev->hpa from an unsigned long to a struct resource. Use insert_resource() instead of request_mem_region(). Request resources at bus walk time instead of driver probe time. Don't release the resources as we don't have any hotplug parisc_device support yet. Add parisc_pathname() to conveniently get the textual representation of the hwpath used in sysfs. Inline the remnants of claim_device() into its caller. Signed-off-by: Matthew Wilcox <willy@parisc-linux.org> I noticed that some of the STI regions weren't showing up in iomem. Reading the STI spec indicated that all STI devices occupy at least 32MB. So check for STI HPAs and give them 32MB instead of 4kB.
