backports: disable some regulator drivers on 3.4 and 3.5

We enabled regulator subsystem support as of 3.4 but given that
the regulator subsystem has advanced quite a bit on 3.5 and 3.6
and that we cannot backport the regulator as its part of the
core kernel we have no option but to only enable drivers on their
kernels if they don't depend on the new regulator features.

compat: backport soc_camera_power_[on|off] for 3.3

We are only backporting CONFIG_SOC_CAMERA for kernels >= 3.4
but there is an exported symbol from there that some media
drivers that we do support on 3.3 need. Handle this special
case.

SOC_CAMERA is only enabled on 3.4 as it depends on some
newer regulator functionality, however there are some SOC
cameras that can rely on the 3.3 regulatory built-in core
and the 3.3 SOC_CAMERA module however two routines are
not exported in that version of SOC_CAMERA that newer
SOC cameras do require. Backport that functionality.

Technically this should go into <media/soc_camera.h>
given that is where its where its exported on linux-next
but in practice only placing it on <linux/v4l2-mediabus.h>
actually fixes linking errors for 3.3 for all SOC camera
drivers we make available for 3.3:

compat: fix dma_common_get_sgtable() backport placements

We added dma_common_get_sgtable() assuming it should only
be available to older kernels as of 3.6 but it was only
up to 3.8 where it was detangled from depending on
CONFIG_HAVE_GENERIC_DMA_COHERENT. Its a mess to express
this on compat files so just word it via kconfig and throw this
onto its own files given that there may be other helpers
we may need to backport later with the same circumstances.

One last hack was required for 3.3-3.6 and that is due
to header changes between kernels.

I attempted to simply not include anything from the

don't include kconfig.h from the command line but

Apparently I missed this during the conversion to the new

backports: add support for voltage / current regulator drivers

This backports the latest regulator drivers for kernels >= 3.4.
We enable the regulator only on kernels >= 3.4 given that
it relies on the new probe deferral mechanism which would
otherwise mean having to support drivers that do not probe
correctly. Note that 3.2 had a base regulator implementation
but that was just stubs.

I did look into a way to upgrade the core kernel regulator
but given that it relies on late_initcall() and core_initcall()
we can't update this part of the kernel. I even looked at
using ksplice for this but it seems ksplice can't be used to
update init sections on the vmlinux ELF. I also haven't much
updates to these routines since 3.4 except for 86f5fcfc.

    resources: Add register address resource type

    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.
