Linus Torvalds 6afd563d4b ARM: SoC driver updates for v4.9
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - The Qualcomm external bus interface 2 (EBI2), used in some of their
   mobile phone chips for connecting flash memory, LCD displays or
   other peripherals
 
 - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the
   EFUSE based on that firmware interface.
 
 - Perf support for the AppliedMicro X-Gene performance monitor unit
 
 - Reset driver for STMicroelectronics STM32
 
 - Reset driver for SocioNext UniPhier SoCs
 
 Aside from these, there are minor updates to SoC-specific bus,
 clocksource, firmware, pinctrl, reset, rtc and pmic drivers.

Johan Hovold 23540d6e2f memory: omap-gpmc: allow probe of child nodes to fail
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.

Linus Torvalds 43a0a98aa8 ARM: SoC driver updates for v4.8
Driver updates for ARM SoCs.
 
 A slew of changes this release cycle. The reset driver tree, that we merge
 through arm-soc for historical reasons, is also sizable this time around.
 
 Among the changes:
 
  - clps711x: Treewide changes to compatible strings, merged here for simplicity.
  - Qualcomm: SCM firmware driver cleanups, move to platform driver
  - ux500: Major cleanups, removal of old mach-specific infrastructure.
  - Atmel external bus memory driver
  - Move of brcmstb platform to the rest of bcm
  - PMC driver updates for tegra, various fixes and improvements
  - Samsung platform driver updates to support 64-bit Exynos platforms
  - Reset controller cleanups moving to devm_reset_controller_register() APIs
  - Reset controller driver for Amlogic Meson
  - Reset controller driver for Hisilicon hi6220
  - ARM SCPI power domain support

Linus Torvalds f64d6e2aaa DeviceTree update for 4.8:
- Removal of most of_platform_populate() calls in arch code. Now the DT
 core code calls it in the default case and platforms only need to call
 it if they have special needs.
 
 - Use pr_fmt on all the DT core print statements.
 
 - CoreSight binding doc improvements to block name descriptions.
 
 - Add dt_to_config script which can parse dts files and list
 corresponding kernel config options.
 
 - Fix memory leak hit with a PowerMac DT.
 
 - Correct a bunch of STMicro compatible strings to use the correct
 vendor prefix.
 
 - Fix DA9052 PMIC binding doc to match what is actually used in dts
 files.

The Kconfig currently controlling compilation of this code is:

drivers/memory/Kconfig:config ATMEL_EBI

...meaning that it currently is not being built as a module by anyone.

Lets remove the few remaining modular references, so that when reading
the driver there is no doubt it is builtin-only.

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

Honghui Zhang 3c8f4ad85c memory/mediatek: add support for mt2701
Mediatek SMI has two generations of HW architecture, mt8173 uses the
second generation of SMI HW while mt2701 uses the first generation
HW of SMI.

There's slight differences between the two generations, for generation 2,
the register which control the iommu port access PA or IOVA is at each
larb's register base. But for generation 1, the register is at smi ao
base(smi always on register base).
Besides that, the smi async clock should be prepared and enabled for SMI
generation 1 HW to transform the smi clock into emi clock domain, but is
not needed for SMI generation 2.

This patch add SMI driver for mt2701 which use generation 1 SMI HW.

Ocquidant, Sebastien 8f50b8e574 memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing
In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY
is overwritten by the WEEXTRADELAY value from the device tree and
GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device
tree.

As a consequence, the memory accesses cannot be configured properly when
the extra delay are needed for OE and WE.

Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the
device tree file and prevents GPMC_CONFIG4_OEXTRADELAY
being overwritten by the WEXTRADELAY value from the device tree.

Boris Brezillon 6a4ec4cd08 memory: add Atmel EBI (External Bus Interface) driver
The EBI (External Bus Interface) is used to access external peripherals
(NOR, SRAM, NAND, and other specific devices like ethernet controllers).
Each device is assigned a CS line and an address range and can have its
own configuration (timings, access mode, bus width, ...).
This driver provides a generic DT binding to configure a device according
to its requirements.
For specific device controllers (like the NAND one) the SMC timings
should be configured by the controller driver through the matrix and
smc syscon regmaps.

  * Replaced the nand_ecclayout infrastructure with something a little more

  * Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some of

  * Prepare the sunxi NAND driver to receive DMA support
  * Handle bitflips in erased pages on GPMI revisions that do not support

Pavel Fedin 8ac2266d88 memory: samsung: exynos-srom: Add support for bank configuration
Implement handling properties in subnodes and adding child devices to the

Since the driver now does more than suspend-resume support, dependency on
CONFIG_PM is removed.
