  * Add new Hisilicon SPI flash controller driver

Linus Torvalds dd9671172a IOMMU Updates for Linux v4.8
In the updates:
 
 	* Big endian support and preparation for defered probing for the
 	  Exynos IOMMU driver
 
 	* Simplifications in iommu-group id handling
 
 	* Support for Mediatek generation one IOMMU hardware
 
 	* Conversion of the AMD IOMMU driver to use the generic IOVA
 	  allocator. This driver now also benefits from the recent
 	  scalability improvements in the IOVA code.
 
 	* Preparations to use generic DMA mapping code in the Rockchip
 	  IOMMU driver
 
 	* Device tree adaption and conversion to use generic page-table
 	  code for the MSM IOMMU driver
 
 	* An iova_to_phys optimization in the ARM-SMMU driver to greatly
 	  improve page-table teardown performance with VFIO
 
 	* Various other small fixes and conversions

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.

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.

The OMAP GPMC module has certain registers dedicated for NAND
access and some NAND bits mixed with other GPMC functionality.

For the NAND dedicated registers we have the struct gpmc_nand_regs.

The NAND driver needs to access NAND specific bits from the
following non-dedicated registers
- EMPTYWRITEBUFFERSTATUS from GPMC_STATUS

For accessing these bits we introduce the struct gpmc_nand_ops.

Add gpmc_omap_get_nand_ops() that returns the gpmc_nand_ops along
with updating the gpmc_nand_regs. This API will be called by the
OMAP NAND driver to access the necessary bits in GPMC register space.

Lijun Pan c4aa1937b7 fsl-ifc: add missing include on ARM64
Need to include sched.h to fix the following compilation error
if FSL_IFC is enabled on ARM64 machine.

In file included from include/linux/mmzone.h:9:0,
                 from include/linux/gfp.h:5,
                 from include/linux/kmod.h:22,
                 from include/linux/module.h:13,
                 from drivers/memory/fsl_ifc.c:22:
drivers/memory/fsl_ifc.c: In function ‘check_nand_stat’:
include/linux/wait.h:165:35: error: ‘TASK_NORMAL’ undeclared (first use in this function)
 #define wake_up(x)   __wake_up(x, TASK_NORMAL, 1, NULL)
                                   ^
drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
   wake_up(&ctrl->nand_wait);
   ^
include/linux/wait.h:165:35: note: each undeclared identifier is reported only once for each function it appears in
 #define wake_up(x)   __wake_up(x, TASK_NORMAL, 1, NULL)
                                   ^
drivers/memory/fsl_ifc.c:136:3: note: in expansion of macro ‘wake_up’
   wake_up(&ctrl->nand_wait);
   ^

Analysis is as follows:
I put some instrumental code and get the
following .h files inclusion sequence:

In file included from ./arch/arm64/include/asm/compat.h:25:0,
                 from ./arch/arm64/include/asm/stat.h:23,
                 from include/linux/stat.h:5,
                 from include/linux/module.h:10,
                 from drivers/memory/fsl_ifc.c:23:
include/linux/sched.h:113:1: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘struct’
 struct sched_attr {
 ^

CONFIG_COMPAT=y is enabled while 39 and 48 bit VA is selected.
When 42 bit VA is selected, it does not enable CONFIG_COMPAT=y

In ./arch/arm64/include/asm/stat.h:23, it has
"#ifdef CONFIG_COMPAT"
"#include <asm/compat.h>"
"..."
"#endif"

Since ./arch/arm64/include/asm/stat.h does not
include ./arch/arm64/include/asm/compat.h,
then it will not include include/linux/sched.h
Hence we have to manually add "#include <linux/sched.h>"
in drivers/memory/fsl_ifc.c

Vince Hsu e2127ae7a5 memory/tegra: Add number of TLB lines for Tegra124
Tegra124 was accidentally left out when the number of TLB lines was
parameterized in commit 11cec15bf3 ("iommu/tegra-smmu: Parameterize
number of TLB lines"). Fortunately this doesn't cause any noticeable
regressions upstream, presumably because there aren't any use-cases
that exercise enough pressure on the SMMU. But it is a regression
nonetheless, so let's fix it.
