PRM device instance offset is now provided through the prm_init_data.
This gets rid of some cpu_is_X / soc_is_X calls from PRM core code,
preparing for PRM to be its own separate driver.

This gets rid of need for some exported driver APIs, and simplifies the
initialization of the PRM driver. Done in preparation to make PRM a
separate driver. The init data is now also passed to the SoC specific
implementations, allowing future expansion to add feature flags etc.

There is no need to provide the control module base address through a
low-level API from the low-level IO init, as this information is
available through DT. This patch adds a new API to initialize the
control module though, but mostly makes the old API obsolete. The
old API can be completely removed once OMAP3 is made DT only.

Splits the clock related provider module inits under their own driver files.
Previously this was done for all modules under the common PRM driver.

Splits the clock provider init out of the PRM driver and moves it to
clock driver. This is needed so that once the PRCM drivers are separated,
they can logically just access the clock driver not needing to go through
common PRM code. This would be wrong in the case of control module for
example.

OMAP4 has different ordering of PRM and CM init calls in the early init.
Re-oder these accordingly for OMAP4 also. This is needed so that we

There is no need to call this separately from io.c, rather this can be
done commonly under the CM driver. Also, this patch makes the API static,
as it is no longer used outside the driver file.

Pull clock framework updates from Mike Turquette:
"The clock framework changes contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
devices.
Additionally the framework core underwent a bit of surgery with two
major changes:
- The boundary between the clock core and clock providers (e.g clock
drivers) is now more well defined with dedicated provider helper
functions. struct clk no longer maps 1:1 with the hardware clock
but is a true per-user cookie which helps us tracker users of
hardware clocks and debug bad behavior.
- The addition of rate constraints for clocks. Rate ranges are now
supported which are analogous to the voltage ranges in the
regulator framework.
Unfortunately these changes to the core created some breakeage. We
think we fixed it all up but for this reason there are lots of last
minute commits trying to undo the damage"

There doesn't seem to be any valid reason to allocate the pages array
with the same flags as the buffer itself. Doing so can eventually lead
to the following safeguard in mm/slab.c's cache_grow() to be hit:
if (unlikely(flags & GFP_SLAB_BUG_MASK)) {
pr_emerg("gfp: %un", flags & GFP_SLAB_BUG_MASK);
BUG();
}
This happens when buffers are allocated with __GFP_DMA32 or
__GFP_HIGHMEM.
Fix this by allocating the pages array with GFP_KERNEL to follow what is
done elsewhere in this file. Using GFP_KERNEL in __iommu_alloc_buffer()
is safe because atomic allocations are handled by __iommu_alloc_atomic().

of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime. All functions working with of_device_ids

The definition
static const char *axxia_dt_match[] __initconst = {
...
defines a changable array of constant strings. That is you must not do:
*axxia_dt_match[0] = 'k';
but
axxia_dt_match[0] = "different string";
is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.
As the struct machine_desc member dt_compat is declared as
const char *const *dt_compat;
making the arrays const is the better alternative over changing all
annotations to __initdata.

davinci_cfg_reg gets called from a lot of locations that
might get called after the init section has been discarded,
so the function itself must not be marked __init either.
The kernel build currently warns about this with lots of
messages like:
WARNING: vmlinux.o(.text.unlikely+0x24c): Section mismatch in reference from the function dm365evm_mmc_configure() to the function .init.text:davinci_cfg_reg()
The function dm365evm_mmc_configure() references
the function __init davinci_cfg_reg().
This is often because dm365evm_mmc_configure lacks a __init
annotation or the annotation of davinci_cfg_reg is wrong.
This removes the extraneous __init_or_module annotation.

Pull ARM SoC DT updates from Olof Johansson:
"DT changes continue to be the bulk of our merge window contents.
We continue to have a large set of changes across the board as new
platforms and drivers are added.
Some of the new platforms are:
- Alphascale ASM9260
- Marvell Armada 388
- CSR Atlas7
- TI Davinci DM816x
- Hisilicon HiP01
- ST STiH418
There have also been some sweeping changes, including relicensing of
DTS contents from GPL to GPLv2+/X11 so that the same files can be
reused in other non-GPL projects more easily. There's also been
changes to the DT Makefile to make it a little less conflict-ridden
and churny down the road"

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson:
"New and updated SoC support. Also included are some cleanups where
the platform maintainers hadn't separated cleanups from new developent
in separate branches.
Some of the larger things worth pointing out:
- A large set of changes from Alexandre Belloni and Nicolas Ferre
preparing at91 platforms for multiplatform and cleaning up quite a
bit in the process.
- Removal of CSR's "Marco" SoC platform that never made it out to the
market. We love seeing these since it means the vendor published
support before product was out, which is exactly what we want!
New platforms this release are:
- Conexant Digicolor (CX92755 SoC)
- Hisilicon HiP01 SoC
- CSR/sirf Atlas7 SoC
- ST STiH418 SoC
- Common code changes for Nvidia Tegra132 (64-bit SoC)
We're seeing more and more platforms having a harder time labelling
changes as cleanups vs new development -- which is a good sign that
we've come quite far on the cleanup effort. So over time we might
start combining the cleanup and new-development branches more"

"isil" and "isl" prefixes are used at various locations inside the kernel
to reference Intersil corporation. This patch is part of a series fixing
those locations were "isl" is used in compatible strings to use the now
expected "isil" prefix instead (NASDAQ symbol for Intersil and most used
version).
Note: isl9305 is an I2C device so the patch does not in fact currently
depend on the introduction of "isil"-based compatible string in isl9305
driver (provided by another patch) because I2C core does not check the
prefix yet.
