553911c67e dmaengine updates for 4.8-rc1
This is bit large pile of code which bring in some nice additions:
  - Error reporting: we have added a new mechanism for users of dmaenegine to
    register a callback_result which tells them the result of the dma
    transaction. Right now only one user ntb is using it.
  - As we discussed on KS mailing list and pointed out NO_IRQ has no place in
    kernel, this also remove NO_IRQ from dmaengine subsystem (both arm and
    ppc users)
  - Support for IOMMU slave transfers and it implementation for arm.
  - To get better build coverage, enable COMPILE_TEST for bunch of driver,
    and fix the warning and sparse complaints on these.
  - Apart from above, usual updates spread across drivers.

In addition to a slew of minor fixes and cleanups these patches refactors how
 we deal with remoteprocs that will be auto-booting themselves, this in itself
 do clean up the remote resource handling but opens for additional work to
 clarify responsibilities and life cycles of resources. We also revise how
 module locking of remoteproc drivers work, so that they are locked as we hand
 out references to them to third parties, rather than only when booted by
 anyone.
 
 In addition to this we also introduce the Qualcomm Wireless Subsystem

6a497e9d58 This is the bulk of GPIO changes for the v4.9 series:
Subsystem improvements:
 
 - Do away with the last users of the obsolete Kconfig options
   ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
   always sounded like an item on a wishlist to Santa Claus to
   me). We can now select GPIOLIB and be done with it, for all
   archs. After some struggle it even work on UM. Not that it has
   GPIO, but if it wants to, it can select the library.
 
 - Continued efforts to make drivers properly either tristate or
   bool.
 
 - Introduce a warning for drivers assigning default triggers to
   their irqchip lines when probed from device tree, so we find and
   fix these ambigous drivers. It is agreed that in the OF config
   path, the device tree defines trigger characteristics.
 
 - The same warning, mutatis mutandis, for ACPI-probed GPIO
   irqchips.
 
 - We introduce the ability to mark certain IRQ lines as "unusable"
   as they can be taken by BIOS/firmware, unrouted in silicon and
   generally nasty if you use them, and such things. This is
   put to good use in the STMPE driver and also in the Cherryview
   pin control driver.
 
 - A new "mockup" virtual GPIO device that can be used for testing.
   The plan is to add unit tests under tools/* for exercising this
   device and verify that the kernel code paths are working as they
   should.
 
 - Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
   implicit all the time, but when people started building UM
   with allyesconfig or allmodconfig it exploded in their face.
 
 - Move some stray bits of device tree and ACPI HW description
   callbacks down into their respective implementation silo. These
   were causing issues when compiling on !HAS_IOMEM as well, so
   now eventually UM compiles the GPIOLIB library if it wants to.
 
 New drivers:
 
 - New driver for the Aspeed GPIO front-end companion to the
   pin controller merged through the pin control tree.
 
 - New driver for the LP873x PMIC GPIO portions.
 
 - New driver for Technologic Systems' I2C FPGA GPIO such as
   TS4900, TS-7970, TS-7990 and TS-4100.
 
 - New driver for the Broadcom BCM63xx series including BCM6338
   and BCM6345.
 
 - New driver for the Intel WhiskeyCove PMIC GPIO.
 
 - New driver for the Allwinner AXP209 PMIC GPIO portions.
 
 - New driver for Diamond Systems 48 line GPIO-MM, another of
   these port-mapped I/O expansion cards.
 
 - Support the STMicroelectronics STMPE1600 variant in the STMPE
   driver.
 
 Driver improvements:
 
 - The STMPE driver now supports rising/falling edge detection
   properly for IRQs.
 
 - The PCA954x will now fetch and enable its VCC regulator properly.
 
 - Major rework of the PCA953x driver with the goal of eventually
   switching it over to use regmap and thus modernize it even more.
 
 - Switch the IOP driver to use the generic MMIO GPIO library.
 
 - Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
   over to this subsystem from MFD, achieveing some separation of
   concerns.

34681d84a0 dmaengine: s3c24xx: Add dma_slave_map for s3c2440 devices
This patch updates the s3c24xx dma driver to be able to pass a
dma_slave_map array via the platform data. This is needed to
be able to use the new, simpler dmaengine API [1].
I used the virtual DMA channels as a parameter for the dma_filter
function. By doing that, I could reuse the existing filter function in
drivers/dma/s3c24xx-dma.c.

I have tested this on my mini2440 board with the audio driver.
According to my observations, dma_request_slave_channel in the
function dmaengine_pcm_new in the file
sound/soc/soc-generic-dmaengine-pcm.c now returns a valid DMA channel
whereas before no DMA channel was returned at that point.

Entries for DMACH_XD0, DMACH_XD1 and DMACH_TIMER are missing because I
don't realy know which driver to use for these.

This patch removes the soc_camera API dependency from pxa_camera.
In the current status :
 - all previously captures are working the same on pxa270
 - the s_crop() call was removed, judged not working
   (see what happens soc_camera_s_crop() when get_crop() == NULL)
 - if the pixel clock is provided by then sensor, ie. not MCLK, the dual
   stage change is not handled yet.
   => there is no in-tree user of this, so I'll let it that way

 - the MCLK is not yet finished, it's as in the legacy way,
   ie. activated at video device opening and closed at video device
   closing.
   In a subsequence patch pxa_camera_mclk_ops should be used, and
   platform data MCLK ignored. It will be the sensor's duty to request
   the clock and enable it, which will end in pxa_camera_mclk_ops.

5fb23e35ca dmaengine: dw: override LLP support if asked in platform data
There are at least two known devices, e.g. DMA controller found on ARC AXS101
SDP board, that have LLP register and no multi block transfer support at the
same time.

Override autodetection by user provided data.

c072e113b8 dmaengine: dw: set polarity of handshake interface
Intel Quark UART uses DesignWare DMA IP. Though the DMA IP is connected in such
way that handshake interface uses inverted polarity. We have to provide a
possibility to set this in the DMA driver when configuring a channel.

Introduce a new member of custom slave configuration called 'hs_polarity' and
set active low polarity in case this value is 'true'.

7ae0ae4a02 spi: Updates for v4.8
Quite a lot of cleanup and maintainence work going on this release in
 various drivers, and also a fix for a nasty locking issue in the core:
 
  - A fix for locking issues when external drivers explicitly locked the
    bus with spi_bus_lock() - we were using the same lock to both control
    access to the physical bus in multi-threaded I/O operations and
    exclude multiple callers.  Confusion between these two caused us to
    have scenarios where we were dropping locks.  These are fixed by
    splitting into two separate locks like should have been done
    originally, making everything much clearer and correct.
  - Support for DMA in spi_flash_read().
  - Support for instantiating spidev on ACPI systems, including some test
    devices used in Windows validation.
  - Use of the core DMA mapping functionality in the McSPI driver.
  - Start of support for ThunderX SPI controllers, involving a very big
    set of changes to the Cavium driver.
  - Support for Braswell, Exynos 5433, Kaby Lake, Merrifield, RK3036,
    RK3228, RK3368 controllers.

Add a new read function to the at24 driver allowing to retrieve the
factory-programmed mac address embedded in chips from the at24mac
family.

These chips can be instantiated similarily to the at24cs family,
except that there's no way of having access to both the serial number
and the mac address at the same time - the user must instantiate
either an at24cs or at24mac device as both special memory areas are
accessible on the same slave address.

818d0220d8 eeprom: at24: support reading the serial number for 24csxx
The chips from the at24cs family have two memory areas - a regular
read-write block and a read-only area containing the serial number.

The latter is visible on a different slave address (the address of the
rw memory block + 0x08). In order to access both blocks the user needs
to instantiate a regular at24c device for the rw block address and a
corresponding at24cs device on the serial number block address.

Add a function that allows to access the serial number and assign it
to at24->read_func if the chip allows serial number read operations
and the driver was passed the relevant flag for this device.

53ae95f6d5 ARM: OMAP3: McBSP: New callback for McBSP2/3 ICLK idle configuration
McBSP2/3 module's sidetone module operates using the module's ICLK clock.
When the Sidetone is in use the interface clock of the module must not
idle. The new callback expects to receive the *clk of the module's ick and
not the id number of the McBSP. This will allow us more cleanups and going
to simplify the ICLK handling.

967dd82ffc net: dsa: b53: Add support for Broadcom RoboSwitch
This patch adds support for Broadcom's BCM53xx switch family, also known
as RoboSwitch. Some of these switches are ubiquituous, found in home
routers, Wi-Fi routers, DSL and cable modem gateways and other
networking related products.

This drivers adds the library driver (b53_common.c) as well as a few bus
glue drivers for MDIO, SPI, Switch Register Access Block (SRAB) and
memory-mapped I/O into a SoC's address space (Broadcom BCM63xx/33xx).

Basic operations are supported to bring the Layer 1/2 up and running,
but not much more at this point, subsequent patches add the remaining
features.

8bc4d5f394 MTD updates for v4.7:
First cycle with Boris as NAND maintainer! Many (most) bullets stolen from him.
 
 Generic:
 
  * Migrated NAND LED trigger to be a generic MTD trigger
 
 NAND:
 
  * Introduction of the "ECC algorithm" concept, to avoid overloading the ECC
    mode field too much more
  * Replaced the nand_ecclayout infrastructure with something a little more
    flexible (finally!) and future proof
  * Rework of the OMAP GPMC and NAND drivers; the TI folks pulled some of
    this into their own tree as well
  * Prepare the sunxi NAND driver to receive DMA support
  * Handle bitflips in erased pages on GPMI revisions that do not support
    this in hardware.
 
 SPI NOR:
 
  * Start using the spi_flash_read() API for SPI drivers that support it (i.e.,
    SPI drivers with special memory-mapped flash modes)
 
 And other small scattered improvments.

2f37dd131c Staging and IIO driver update for 4.7-rc1
Here's the big staging and iio driver update for 4.7-rc1.
 
 I think we almost broke even with this release, only adding a few more
 lines than we removed, which isn't bad overall given that there's a
 bunch of new iio drivers added.  The Lustre developers seem to have
 woken up from their sleep and have been doing a great job in cleaning up
 the code and pruning unused or old cruft, the filesystem is almost
 readable :)
 
 Other than that, just a lot of basic coding style cleanups in the churn.
 All have been in linux-next for a while with no reported issues.

f2b1e0f638 ARM: SoC cleanups and fixes for v4.7
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.
