Manuel Lauss d4f07ae748 MIPS, IDE: Alchem, au1xxx-ide: Remove pb1200/db1200 header dep
au1xxx-ide uses defines from the pb1200/db1200 headers:
get DBDMA ID through platform resource information,
hardcode register spacing.  The only 2 users of this driver (and
the only boards it can really work on realiably) use the same
register layout.

Manuel Lauss 963accbc82 MIPS: Alchemy: change dbdma to accept physical memory addresses
DMA can only be done from physical addresses; move the "virt_to_phys"
source/destination buffer address translation from the dbdma queueing
functions (since the hardware can only DMA to/from physical addresses)
to their respective users.

(Queueing function signature has changed in order to give
 a build failure instead of silent functional changes due
 to the no longer implicitly specified DDMA_FLAGS_IE flag)

Ming Lei 7a192ec334 platform driver: fix incorrect use of 'platform_bus_type' with 'struct device_driver'
This patch fixes the bug reported in
	http://bugzilla.kernel.org/show_bug.cgi?id=11681.

"Lots of device drivers register a 'struct device_driver' with
the '.bus' member set to '&platform_bus_type'. This is wrong,
since the platform_bus functions expect the 'struct device_driver'
to be wrapped up in a 'struct platform_driver' which provides
some additional callbacks (like suspend_late, resume_early).
The effect may be that platform_suspend_late() uses bogus data
outside the device_driver struct as a pointer pointer to the
device driver's suspend_late() function or other hard to
reproduce failures."(Lothar Wassmann)
