of_parse_phandle_with_args() needs to return quite a bit of data. Rather than making each datum a separate **out_ argument, this patch creates struct of_phandle_args to contain all the returned data and reworks the user of the function. This patch also enables of_parse_phandle_with_args() to return the device node pointer for the phandle node. This patch also ends up being fairly major surgery to of_parse_handle_with_args(). The existing structure didn't work well when extending to use of_phandle_args, and I discovered bugs during testing. I also took the opportunity to rename the function to be like the existing of_parse_phandle(). v2: - moved declaration of of_phandle_args to fix compile on non-DT builds - fixed incorrect index in example usage - fixed incorrect return code handling for empty entries Reviewed-by: NShawn Guo <shawn.guo@freescale.com> Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

This allows to load the OF driver based informations from the device tree. Systems without BIOS may need to perform some initialization. PowerPC creates a PNP device from the OF information and performs this kind of initialization in their private PCI quirk. This looks more generic. This patch also avoids registering the platform RTC driver on X86 if we have a device tree blob. Otherwise we would setup the device based on the hardcoded information in arch/x86 rather than the device tree based one.

Commit 7c7b60cb "of: put default string compare and #a/s-cell values into common header" Breaks various things on powerpc due to using strncasecmp instead of strcasecmp for comparing against "compatible" strings. This causes things like the 4xx PCI code to fail miserably due to the partial matches in code like this: for_each_compatible_node(np, NULL, "ibm,plb-pcix") ppc4xx_probe_pcix_bridge(np); for_each_compatible_node(np, NULL, "ibm,plb-pci") ppc4xx_probe_pci_bridge(np); It's not quite right to do partial name match. Entries in a compatible list are meant to be matched whole. If a device is compatible with both "foo" and "foo1", then the device should have both strings in its "compatible" property. This patch reverts powerpc and microblaze us to use strcasecmp.

In struct device_node, the phandle is named 'linux_phandle' for PowerPC and MicroBlaze, and 'node' for SPARC. There is no good reason for the difference, it is just an artifact of the code diverging over a couple of years. This patch renames both to simply .phandle. Note: the .node also existed in PowerPC/MicroBlaze, but the only user seems to be arch/powerpc/platforms/powermac/pfunc_core.c. It doesn't look like the assignment between .linux_phandle and .node is significantly different enough to warrant the separate code paths unless ibm,phandle properties actually appear in Apple device trees. I think it is safe to eliminate the old .node property and use phandle everywhere. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.

Special case of of_read_ulong() was defined for PPC32 to toss away all but the last 32 bits when a large number value was read, and the 'normal' version for ppc64 just #defined of_read_ulong to of_read_number which causes compiler warnings on MicroBlaze and other 32 bit architectures because it returns a u64 instead of a ulong. This patch fixes the problem by defining a common implementation of of_read_ulong() that works everywhere.
