Most of IP's in AM335x is present on AM43x and so in those cases both
will use same hwmod database (except for a few cases where clock related
details differ), but there is difference w.r.t register offset between
these. Update register offsets at runtime based on the SoC detected to
help in sharing otherwise same hwmod.

AM335x and AM43x have most of the IP's and interconnect's similar.
Instead of adding redundant hwmod data, move interconnects and hwmod
similar between AM335x and AM43x to a common location. This helps in
reuse on AM43x.
AM335x interconnects that has difference and not present in AM43x are
not moved. ocp clock of those in l4_wkup is fed from a different source
for AM43x. Also pruss interconnect is different.
AM335x hwmod's that has difference other than prcm register offsets
(difference is in clocks of wkup_m3, control, gpio0, debugss and clock
domain of l4_hs, adc_tsc as compared to AM43x) and those that are not
present in AM43x are not moved.

Most of the AM43x CM reg address offsets are with MSB bit '1' (on
16-bit value) leading to arithmetic miscalculations while calculating
CLOCK ENABLE register's address because cm_inst field was a type of
"const s16", so make it "const u16".
Also modify relevant functions so as to take care of the above.

The hwmod init sequence involves initializing and idling all the
hwmods during bootup. If a module class has sysconfig, the init
sequence utilizes the module register base for performing any
sysc configuration.
The module address space is being removed from hwmod database and
retrieved from the <reg> property of the corresponding DT node.
If a hwmod does not have its corresponding DT node defined and the
memory address space is not defined in the corresponding
omap_hwmod_ocp_if, then the module register target address space
would be NULL and any sysc programming would result in a NULL
pointer dereference and a kernel boot hang.
Handle this scenario by checking for a valid module address space
during the _init of each hwmod, and leaving it in the registered
state if no module register address base is defined in either of
the hwmod data or the DT data.

This branch contains mostly additions and changes to platform enablement
and SoC-level drivers. Since there's sometimes a dependency on device-tree
changes, there's also a fair amount of those in this branch.
Pieces worth mentioning are:
- Mbus driver for Marvell platforms, allowing kernel configuration
and resource allocation of on-chip peripherals.
- Enablement of the mbus infrastructure from Marvell PCI-e drivers.
- Preparation of MSI support for Marvell platforms.
- Addition of new PCI-e host controller driver for Tegra platforms
- Some churn caused by sharing of macro names between i.MX 6Q and 6DL
platforms in the device tree sources and header files.
- Various suspend/PM updates for Tegra, including LP1 support.
- Versatile Express support for MCPM, part of big little support.
- Allwinner platform support for A20 and A31 SoCs (dual and quad Cortex-A7)
- OMAP2+ support for DRA7, a new Cortex-A15-based SoC.
The code that touches other architectures are patches moving
MSI arch-specific functions over to weak symbols and removal of
ARCH_SUPPORTS_MSI, acked by PCI maintainers.

Pull OMAP specific fbdev changes from Tomi Valkeinen:
"I've got this pull request separate from the main fbdev pull request,
as this contains a bunch of OMAP board file changes and thus could
possibly be rejected in case of bad conflicts.
The removal of the old display drivers depend on the board file
changes, so Tony Lindgren suggested taking them together via fbdev
tree. These are in linux-next, and also Tony didn't see any conflicts
with any of the branches he had, so they should go in clean.

The DPI and SDI platform devices are currently created with the ID of
-1. The ID doesn't currently affect anything.
However, we have added regulator supply entries for "omapdss_dpi.0" and
"omapdss_sdi.0" to the board files, although these supply entries are
not yet used. As the ID used for the devices is -1, these regulator
supply entries will not work.
To fix the issue, assign ID of 0 to the devices. In the future there may
be more than one DPI or SDI output, so it makes sense to have a proper
ID for them.

The new OMAP display drivers were merged for 3.11, and we can now change
the board files to use the new ones and phase out the old ones.
Note that the LCD add-on boards for lcd43 and lcd35 use the same GPIOs
for the panels. This means that both panel devices cannot be probed at
the same time.
DT will handle this correctly, i.e. the DT data will contain the panel
device only for the add-on board that is attached. However, for the
board file we need a hackish solution: We parse the kernel boot command
line, and see whether lcd43 or lcd35 is set as a default display, and
add the given one. Or, if neither is given, default to lcd43.
