git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux into fixes
Fixes for 4.12:
Fix two compilation issues
* tag 'at91-4.12-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux:
ARM: at91: select CONFIG_ARM_CPU_SUSPEND
memory: atmel-ebi: mark PM ops as __maybe_unused

We get a harmless warning without CONFIG_PM:
drivers/memory/atmel-ebi.c:584:12: error: 'atmel_ebi_resume' defined but not used [-Werror=unused-function]
Marking the function as __maybe_unused does the right thing here
and drops it silently when unused.

The width needs to be configured in bytes with 1 meaning 8-bit
access and 2 meaning 16-bit access.

Pull MTD updates from Brian Norris:
"NAND, from Boris:
- some minor fixes/improvements on existing drivers (fsmc, gpio, ifc,
davinci, brcmnand, omap)
- a huge cleanup/rework of the denali driver accompanied with core
fixes/improvements to simplify the driver code
- a complete rewrite of the atmel driver to support new DT bindings
make future evolution easier
- the addition of per-vendor detection/initialization steps to avoid
extending the nand_ids table with more extended-id entries
SPI NOR, from Cyrille:
- fixes in the hisi, intel and Mediatek SPI controller drivers
- fixes to some SPI flash memories not supporting the Chip Erase
command.
- add support to some new memory parts (Winbond, Macronix, Micron,
ESMT).
- add new driver for the STM32 QSPI controller
And a few fixes for Gemini and Versatile platforms on physmap-of"

As Freescale/NXP IFC controller is available on LS1021A, the dependency
for LS1021A is added.
LS1021A is an earlier product and is not compatible with later
LayerScape architecture. So ARCH_LAYERSCAPE can't cover LS1021A.

New helpers/macros have been to atmel-smc.h introduced to simplify SMC
regs manipulation. Rework the code to use those helpers, and simplify
the ->xlate_config(), ->get_config() and ->apply_config() implementations.
SMC configs are now stored in a struct atmel_smc_cs_conf object that
directly contains registers values, which should help implementing
->suspend()/->resume() hooks.
We can also get rid of those regmap fields (and the associated ->init()
hook) which are not longer needed thanks to the
atmel_[h]smc_cs_conf_{apply,get}() helpers.

TI aemif driver creates its own subnodes of the device tree in order
to guarantee that all child devices are probed after the AEMIF timing
parameters are configured.
Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup
but nodes created from within the aemif driver can't access the lookup
table.
Create a platform data structure that holds a pointer to
of_dev_auxdata so that we can use it with of_platform_populate().

of_match_device could return NULL, and so cause a NULL pointer
dereference later.
For fixing this problem, we use of_device_get_match_data(), this will
simplify the code a little by using a standard function for
getting the match data.

"gpiochip_free_own_desc"
The gpiochip_free_own_desc() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

A recent commit (inadvertently?) changed how failed probe of a gpmc
child node was handled. Instead of proceeding with setting up any other
children as before, a single error now aborts the whole process.
This change broke networking on some Overo boards due to probe failing
for an unrelated nand node. This second issue should obviously be
fixed, but let's restore the old behaviour of allowing child-node
probe to fail to avoid further similar breakage on other systems.

Quoting Boris:
'This pull request contains only one notable change:
- Addition of the MTK NAND controller driver
And a bunch of specific NAND driver improvements/fixes. Here are the
changes that are worth mentioning:
- A few fixes/improvements for the xway NAND controller driver
- A few fixes for the sunxi NAND controller driver
- Support for DMA in the sunxi NAND driver
- Support for the sunxi NAND controller IP embedded in A23/A33 SoCs
- Addition for bitflips detection in erased pages to the brcmnand driver
- Support for new brcmnand IPs
- Update of the OMAP-GPMC binding to support DMA channel description'
In addition, some small fixes around error handling, etc., as well
as one long-standing corner case issue (2.6.20, I think?) with
writing 1 byte less than a page.
NOR:
- rework some error handling on reads and writes, so we can better
handle (for instance) SPI controllers which have limitations on
their maximum transfer size
- add new Cadence Quad SPI flash controller driver
- add new Atmel QSPI flash controller driver
- add new Hisilicon SPI flash controller driver
- support a few new flash, and update supported features on others
- fix the logic used for detecting a fully-unlocked flash

The Kconfig currently controlling compilation of this code is:
memory/samsung/Kconfig:config EXYNOS_SROM
memory/samsung/Kconfig: bool "Exynos SROM controller driver" if COMPILE_TEST
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
is already contained at the top of the file in the comments.
