of/flattree: Make the kernel accept ePAPR style phandle information Currently when processing flattened device trees, the kernel expects the phandle in a property called "linux,phandle". The ePAPR spec - not being Linux specific - instead requires phandles to be encoded in a property named simply "phandle". This patch makes the kernel accept either form when unflattening the device tree. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

of: unify phandle name in struct device_node 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: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

of: Fix phandle endian issues The flat tree code wasn't fixing the endianness on phandle values when unflattening the tree, and the code in drivers/of wasn't always doing a be32_to_cpu before trying to dereference the phandle values.

of/flattree: Make the kernel accept ePAPR style phandle information Currently when processing flattened device trees, the kernel expects the phandle in a property called "linux,phandle". The ePAPR spec - not being Linux specific - instead requires phandles to be encoded in a property named simply "phandle". This patch makes the kernel accept either form when unflattening the device tree. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
