The removal of mach/io.h from most ARM platforms also set the range of
valid IO ports to be empty for most platforms when previously any 32
bit integer had been valid. This makes it impossible to add IO resources
as the added range is smaller than that of the root resource for IO ports.
Since we're not really using IO memory at all fix this by defining our
own root resource outside the normal tree and make that the parent of
all IO resources. This also ensures we won't conflict with read IO ports
if we ever run on a platform which happens to use them.

The removal of mach/io.h from most ARM platforms also set the range of
valid IO ports to be empty for most platforms when previously any 32
bit integer had been valid. This makes it impossible to add IO resources
as the added range is smaller than that of the root resource for IO ports.
Since we're not really using IO memory at all fix this by defining our
own root resource outside the normal tree and make that the parent of
all IO resources. This also ensures we won't conflict with read IO ports
if we ever run on a platform which happens to use them.

1.7.10.4
Currently a bunch of I2C/SPI MFD drivers are using IORESOURCE_IO for
register address ranges. Since this causes some confusion due to the
primary use of this resource type for PCI/ISA I/O ports create a new
resource type IORESOURCE_REG.
Unfortunately the current resource types are specified as bitmasks and
there are no free bitmasks even though they really shouldn't be used as
such so we define the new type as IORESOURCE_IO | IORESOURCE_MEM.
Benjamin Herrenschmidt and Russell King have both verified that none of
the users in this series will have a problem with this, and no new code
should be affected.
This patch was written by Russell King but he found himself unable to
take the patch further.

Thanks a lot for following through with this series! I would have
preferred to have the second step in stable as Russell suggested,
but since you did all the work, I'm not going to complain about it ;-)

Yeah, it'd be nicer to do it but given that the second step is adding a
new, non-bitmask resource type to a set of resource types that have
previously been all bitmasks I know I'd not get taken seriously
suggesting it as a fix to a system integrator without a big argument
about it and general unhappiness, most people doing stable releases I've
worked with would have a similar response. It's not that it's unsafe,
it's that it sets off alarm bells and requires more due dilligence.
Now resource of 88pm860x backlight is changed from IORESOURCE_IO
to IORESOURCE_REG. In original driver, the resource is using
self-defined IORESOURCE_IO. So change the resource to register
offset to match the definition of IORESOURCE_REG.

1.7.9.5
Since IORESOURCE_IO is changed to IORESOURCE_REG in 88pm860x driver,
update self-defined IORESOURCE_IO resource to register offset that
is IORESOURCE_REG in regulator driver. And split regulator platform
data array into scattered platform data.

And I also attached my 3 patches for 88pm860x since the old self-defined
IORESOURCE_IO should be changed to register offset (IORESOURCE_REG).
Otherwise, it still fails in my platform.

This is not the correct way to submit patches for inclusion in the
stable kernel tree. Please read Documentation/stable_kernel_rules.txt
for how to do this properly.
