Anton Vorontsov 2d5fcc986d pata_of_platform: Don't use NO_IRQ
Drivers should not use NO_IRQ; moreover, some architectures don't
have it nowadays. '0' is the 'no irq' case.

Pawel Moll 37210fbe1d ata: Make pata_of_platform.c compile again and work on non-PPC platforms
This patch adds missing #includes, makes the driver selectable on
non-PPC OF-enabled platforms and fixes property value accesses to
be correct in Little Endian system.

Grant Likely 1c48a5c93d dt: Eliminate of_platform_{,un}register_driver
Final step to eliminate of_platform_bus_type.  They're all just
platform drivers now.

v2: fix type in pasemi_nand.c (thanks to Stephen Rothwell)

Grant Likely 2dc1158137 of/device: Replace struct of_device with struct platform_device
of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then
edited by hand to pick up the bits that coccinelle didn't catch.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

Grant Likely 61c7a080a5 of: Always use 'struct device.of_node' to get device node pointer.
The following structure elements duplicate the information in
'struct device.of_node' and so are being eliminated.  This patch
makes all readers of these elements use device.of_node instead.

(struct of_device *)->node
(struct dev_archdata *)->prom_node (sparc)
(struct dev_archdata *)->of_node (powerpc & microblaze)

Anton Vorontsov 4538d0ca71 powerpc: Fix no interrupt handling in pata_of_platform
When no interrupt is specified the pata_of_platform fills the irq_res
resource with -1, which is wrong to do for two reasons:

1. By definition, 'no irq' should be IRQ 0, not some negative integer;
2. pata_platform checks for irq_res.start > 0, but since irq_res.start
   is unsigned type, the check will be true for `-1'.

Anton Vorontsov 61f7162117 libata: pata_of_platform: OF-Platform PATA device driver
This driver nicely wraps around pata_platform library functions,
and provides OF platform bus bindings to the PATA devices.

Also add || PPC to the PATA_PLATFORM's "depends on" Kconfig entry,
needed for PA Semi Electra.
