Subject[V2 PATCH 00/10] of: Consolidate scattered device node pointers in struct device
Date
Currently, each of_device has a copy of the device tree node pointer in both
.node, and in .dev.archdata.of_node (microblaze and powerpc) or
.dev.archdata.prom_node (sparc). Also, other architectures will be adding
CONFIG_OF support, and they will also need a reference to the device tree
node pointer from struct device.

This series consolidates the device node pointer by adding .of_node to
struct device (conditional on CONFIG_OF) and removing the archdata.of_node,
archdata.prom_node and of_device.node users. The pointer is moved out of
dev_archdata and into struct device proper so that of_node doesn't need to
get manually added to archdata for each architecture that enables CONFIG_OF.

Based on v2.6.34-rc1

Series should be fully bisectable.
- Patch 1 adds the new device.of_node pointer and sets the value in all the
needed places.
- Patches 2-6 eliminate all readers of the old values
- Patch 7 removes references to the archdata stuff from drivers/of (there
are no more users at this point)
- Patches 8-10 finally remove the old versions.

My goal is to get patches 1-5 into linux-next as soon as I've collected acks.
Dave, Michal and Ben, it would be fantastic if you're able to give this
series a spin. Once I've gotten the okay from you I can then start merging
the driver changes from patch 6 as I receive acks from the various subsystem
maintainers (I'm still maintaining the drivers changes in a large series of
per-subsystem patches so I can add them to linux-next as maintainers
respond, but for this posting I've rolled them all up to make it easy to
handle.) I'll add the last 4 patches to linux-next once all the driver
changes are committed.

Build tested on powerpc (32 & 64 bit), sparc (32 & 64), microblaze. Booted
on MPC5200.

Difference from v1:
- some cleanups and fixed more references to the old properties.
- rolled all the drivers/ and sound/ changes into a single patch to
simplify review.

Grant Likely (10):
arch/sparc: Remove obsolete dev_archdata.prom_node and of_devce.node
arch/microblaze: Remove obsolete dev_archdata.of_node and of_devce.node
arch/powerpc: Remove obsolete dev_archdata.of_node and of_devce.node
of: eliminate calls to dev_archdata_set_node()
of/drivers: Always use struct device.of_node to get node pointer
arch/microblaze: Always use 'struct device.of_node' to get device node pointer.
arch/powerpc: Always use 'struct device.of_node' to get device node pointer.
arch/sparc: Always use 'struct device.of_node' to get device node pointer.
i2c/of: Allow device node to be passed via i2c_board_info
driver-core: Add device node pointer to struct device
