Get rid of users of of_platform_driver in drivers/usb. The
of_platform_{,un}register_driver functions are going away, so the
users need to be converted to using the platform_bus_type directly.

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.

Merging in current state of Linus' tree to deal with merge conflicts and
build failures in vio.c after merge.
Conflicts:
drivers/i2c/busses/i2c-cpm.c
drivers/i2c/busses/i2c-mpc.c
drivers/net/gianfar.c
Also fixed up one line in arch/powerpc/kernel/vio.c to use the
correct node pointer.

.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.

Use the resource_size function instead of manually calculating the

The usbcore headers: hcd.h and hub.h are shared between usbcore,
HCDs and a couple of other drivers (e.g. USBIP modules).
So, it makes sense to move them into a more public location and
to cleanup dependency of those modules on kernel internal headers.
This patch moves hcd.h from drivers/usb/core into include/linux/usb/

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)

The match_table field of the struct of_device_id is constant in <linux/of_platform.h>
so it is worth to make the initialization data also constant.

Platform device support was merged earlier, but support for boards to
customize the devflags aspect of the controller was not. We want this on
Blackfin systems to control the bus width, but might as well expose all of
the fields while we're at it.

Currently, the driver only supports PCI and PPC_OF but there are
boards like ARM RealView where this is a platform device. The patch adds
the necessary functions and registration to the isp1760-if.c file and
modifies the corresponding Makefile and Kconfig to be able to use this
driver even if PCI and PPC_OF are not enabled.

There is no need to disable port 1 on ISP1761. That port could
be used as an OTG port which would require a different init
sequence. However we don't have OTG support (yet) so we can use
it as a normal USB port.
This patch allows port 1 to be used a normal Port on the ISP1761.

Contains fixes so probe on x86 PCI runs, apparently I'm first to try
this. Several fixes to memory access to probe host scratch register.
Previously would bug check on chip_addr var used uninitialized.
Scratch reg write failed in one instance due to 16-bit initial access
mode, so added "& 0x0000ffff" to the readl as fix.
Includes some general cleanup - remove global vars, organize memory map
resource use.

this driver can't handle (of course) any brdige class devices. So we
now are just active on one specific bridge which should be only the
isp1761 chip behind a PLX bridge.

The reason, is that ret is initialized with ENODEV instead of 0 _or_
the kmem cache is not freed in error case with no bus binding.

about 1.5 KiB.
Until there is a checkbox where the user *must* select atleast one item,
and may select multiple entries I don't make it selectable anymore.
Having a driver which can't be used under any circumstances is broken
anyway and I've seen distros shipping it that way.

USB should not be having it's own printk macros, so remove err() and
use the system-wide standard of dev_err() wherever possible. In the
few places that will not work out, use a basic printk().

In case of error, the function isp1760_register returns an ERR
pointer, but never returns a NULL pointer. So after a call to this
function, a NULL test should be replaced by an IS_ERR test. Moreover,
we have noticed that:
(1) the result of isp1760_register is assigned through the function
pci_set_drvdata without an error test,
(2) if the call to isp1760_register fails, the current function
(isp1761_pci_probe) returns 0, and if it succeeds, it returns -ENOMEM,
which seems odd.
Thus, we suggest to move the test before the call to pci_set_drvdata
to correct (1), and to turn it into a non IS_ERR test to correct (2).
The semantic match that finds this problem is as follows:

This adds support for hardware configurations that don't match the
chip default register settings (e.g., 16-bit data bus, DACK and
DREQ pulled up instead of down, analog overcurrent mode).
These settings are passed in via the OF device tree. The PCI
interface still assumes the same default values.

not. However, it works on my little PowerPC board.
