46673ed2cd rdc321x-southbridge: Use mfd_data instead of driver_data
Use mfd_data for passing information from mfd drivers to soc
clients.  The mfd_cell's driver_data field is being phased out.

Clients that were using driver_data now access .mfd_data
via mfd_get_data().

3b3c1f24e9 watchdog: Fix null pointer dereference while accessing rdc321x platform_data
rdc321x-wdt currently fetches its driver specific data by using the
platform_device->platform_data pointer, this is wrong because the mfd
device which registers our platform_device has been added using
mfd_add_device() which sets the platform_device->driver_data pointer
instead.

8deca39e5c mfd: Change rdc321x resources flags to IORESOURCE_IO
The rdc321x southbridge PCI device has no MEM PCI resources that we could
pass to mfd_add_devices. Since 33254dd5, mfd_add_device checks for the
mem_base argument that we set to NULL. Changing the resources passed to
our MFD cells from IORESOURCE_MEM to IORESOURCE_IO fixes that. Since we use
those resources as offsets to the PCI configuration space base address of
the southbridge device this is also more adequate.

842102f35a watchdog: Convert rdc321x_wdt to use southbridge pci device
The RDC321x MFD southbridge driver will pass a reference to the
southbridge PCI device which should be used by the watchdog driver for its
operations.  This patch converts the watchdog driver to use the pci_dev
pointer and make use of the base register resource which is passed along
with the platform device.

b6bf291f1c [WATCHDOG] move platform probe and remove function to devinit and devexit
A pointer to probe and remove functions is passed to the core via
platform_driver_register and so the function must not disappear when the
.init sections are discarded.  Otherwise (if also having HOTPLUG=y)
unbinding and binding a device to the driver via sysfs will result in an
oops as does a device being registered late.

5662a2f8e7 x86, rdc321x: remove/move leftover files
Impact: cleanup

Move/remove leftover RDC321 files. Now that it's not a subarch anymore,
arch/x86/mach-rdc321x and arch/x86/include/asm/mach-rdc321x/ are not
needed.

One include file was still in use: rdc321x_defs.h, move that to the
generic x86 asm header directory.
