[ Upstream commit 6862fdf2201ab67cd962dbf0643d37db909f4860 ]
"S3C2410 PM Suspend Memory CRC" feature (controlled by
SAMSUNG_PM_CHECK config option) is incompatible with highmem
(uses phys_to_virt() instead of proper mapping) which is used by
the majority of Exynos boards. The issue manifests itself in OOPS
on affected boards, i.e. on Odroid-U3 I got the following one:
Unable to handle kernel paging request at virtual address f0000000
pgd = 1c0f9bb4
[f0000000] *pgd=00000000

commit b9a1a743818ea3265abf98f9431623afa8c50c86 upstream.
ARM64 allmodconfig produces a bunch of warnings when building the
samsung ASoC code:
sound/soc/samsung/dmaengine.c: In function 'samsung_asoc_init_dma_data':
sound/soc/samsung/dmaengine.c:53:32: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
playback_data->filter_data = (void *)playback->channel;
sound/soc/samsung/dmaengine.c:60:31: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast]
capture_data->filter_data = (void *)capture->channel;
We could easily shut up the warning by adding an intermediate cast,
but there is a bigger underlying problem: The use of IORESOURCE_DMA
to pass data from platform code to device drivers is dubious to start
with, as what we really want is a pointer that can be passed into
a filter function.
Note that on s3c64xx, the pl08x DMA data is already a pointer, but
gets cast to resource_size_t so we can pass it as a resource, and it
then gets converted back to a pointer. In contrast, the data we pass
for s3c24xx is an index into a device specific table, and we artificially
convert that into a pointer for the filter function.

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"

Due to recently merged patches and previous merge conflicts, the Samsung
PM Debug functionality no longer can be enabled. This patch fixes
incorrect dependency of SAMSUNG_PM_DEBUG on an integer symbol and adds
missing header inclusion.

* cleanup/gpio-header-removal:
ARM: delete old reference to ARM_GPIOLIB_COMPLEX
ARM: kill CONFIG_NEED_MACH_GPIO_H
ARM: mach-s5p: get rid of all <mach/gpio.h> headers
ARM: s5p: cut the custom ARCH_NR_GPIOS definition
This resolves a massive amount of conflicts between the
mach/gpio.h removal and the s5p platform removal.
Almost all changes are trivial, as both sides remove
stuff.

Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.
Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

on legacy code, all Kconfig symbols related to Samsung ATAGS support can
be deselected and more unused code removed. This includes most of s5p-*

This renames all the local <mach/gpio.h> headers in the S5P platforms
to <mach/gpio-samsung.h> indicating a scope local to this platform,
and cuts the implicit inclusion of <mach/gpio.h> from <linux/gpio.h>
by removing the use of NEED_MACH_GPIO_H from all S5P variants.

The number of GPIOs defined for the different S5P platforms using
the tricky #define macros are actually as follows:
S5P64x0: 180 GPIOs
S5PC100: 115 GPIOs
S5PV210: 252 GPIOs
The include file <asm-generic/gpio.h> will automatically bump us
to 256 GPIOs which is a nice default value that happens to encompass
all the S5P platform requirements under its roof.
Cut ARCH_NR_GPIOS and the custom spacing macro for extra GPIOs
that is not used anywhere in the kernel.

"A first set of bug fixes that didn't make it for the merge window, and
two Kconfig cleanups that still make sense at this point.
Unfortunately, one of the two cleanups caused an unintended change in
the original version, so we had to revert one part of it and do some
more testing to ensure the rest is really fine. There was also a
last-minute rebase of the patches to remove another bad commit"

The addition of Exynos to multi-platform configs creates a mess of config
options with options appearing before the Exynos config option. This is
due to arch/arm/plat-samsung/Kconfig being included out of order with the
other Samsung platform kconfig files. Reorder the kconfig files and move
all the options into a sub-menu. Some of the options are dead, so remove
those as well.

The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.
This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.
In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.
