Support for TI Message Manager Module. This hardware block manages a
bunch of hardware queues meant for communication between processor
entities.

Clients sitting on top of this would manage the required protocol
for communicating with the counterpart entities.

Rename the pad to sw_data as per description of this field in the hardware
spec(refer sprugr9 from www.ti.com). Latest version of the document is
at http://www.ti.com/lit/ug/sprugr9h/sprugr9h.pdf and section 3.1
Host Packet Descriptor describes this field.

Define and use a constant for the size of sw_data field similar to
other fields in the struct for desc and document the sw_data field
in the header. As the sw_data is not touched by hw, it's type can be
changed to u32.

Rename the helpers to match with the updated dma desc field sw_data.

  Some of the larger updates:

   - Qualcomm support for SMEM, SMSM, SMP2P.  All used to communicate
     with other parts of the chip/board on these platforms, all
     proprietary protocols that don't fit into other subsystems and live
     in drivers/soc for now.

   - System bus driver for UniPhier

   - Driver for the TI Wakeup M3 IPC device

   - Power management for Raspberry PI

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
 "This branch is the culmination of 5 years of effort to bring the ARMv6
  and ARMv7 platforms together such that they can all be enabled and
  boot the same kernel.  It has been a tremendous amount of cleanup and
  refactoring by a huge number of people, and creation of several new
  (and major) subsystems to better abstract out all the platform details
  in an appropriate manner.

  The bulk of this branch is a large patchset from Arnd that brings
  several of the more minor and older platforms we have closer to
  multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
  and realview Much of this is moving around header files from old mach
  directories, but there are also some cleanup patches of debug_ll
  (lowlevel debug per-platform options) and other parts.

  Linus Walleij also has some patchs to clean up the older ARM Realview
  platforms by finally introducing DT support, and Rob Herring has some
  for ARM Versatile which is now DT-only.  Both of these platforms are
  now multiplatform.

  Finally, a couple of patches from Russell for Dove PMU, and a fix from
  Valentin Rothberg for Exynos ADC, which were rebased on top of the
  series to avoid conflicts"

The netcp driver produces tons of warnings when CONFIG_LPAE is enabled
on ARM:

drivers/net/ethernet/ti/netcp_core.c: In function 'netcp_tx_map_skb':
drivers/net/ethernet/ti/netcp_core.c:1084:13: warning: passing argument 1 of 'set_words' from incompatible pointer type [-Wincompatible-pointer-types]

This is the result of trying to pass a pointer to a dma_addr_t to
a function that expects a u32 pointer to copy that into a DMA descriptor.

Looking at that code in more detail to fix the warnings, I see multiple
related problems:

* The conversion functions are not endian-safe, as the DMA descriptors
  are almost certainly fixed-endian, but the CPU is not.

* On 64-bit machines, passing a pointer through a u32 variable is a
  bug, accessing an indirect pointer as a u32 pointer even more so.

* The handling of epib and psdata mixes native-endian and device-endian
  data.

In this patch, I try to sort out the types for most accesses here,
adding le32_to_cpu/cpu_to_le32 where appropriate, and passing pointers
through two 32-bit words in the descriptor padding, to make it plausible
that the driver does the right thing if compiled for big-endian or
64-bit systems.

Add support for legacy non-DT Dove to the PMU driver, so that we can
transition the legacy support over.
