7ae0ae4a02 Merge tag 'spi-v4.8' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi
Pull spi updates from Mark Brown:
 "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"

0b813658c1 eeprom: at24: add support for at24mac series
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.

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.

f2b1e0f638 Merge tag 'armsoc-cleanups-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups and fixes from Arnd Bergmann:
 "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 notable 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"

161c3d04ae dmaengine: dw: keep entire platform data in struct dw_dma
Keep the entire platform data in the struct dw_dma.
It makes the driver a bit cleaner.

2e65060e80 dmaengine: dw: revisit data_width property
There several changes are done here:

- Convert the property to be in bytes

  Besides that this is a common practice for such property, the use of a value
  in bytes much more convenient than handling the encoded one.

- Rename data_width to data-width in the device tree bindings

  The change leaves the support for the old format as well just in case someone
  will use a newer kernel with an old device tree blob.

- While here, replace dwc_fast_ffs() by __ffs()

4ba8cfa79f gpio: dwapb: convert device node to fwnode
This patch converts device node to fwnode for dwapb driver, so
as to provide a unified fwnode for DT and ACPI bindings.

e81591815d gpio: dwapb: remove name from dwapb_port_property
This patch removed the name property from dwapb_port_property.
The name property is redundant, since we can get this info
from dwapb_gpio dev node.

8453c5cafd ARM: OMAP2+: Add more functions to pwm pdata for ir-rx51
Before we start removing omap3 legacy booting support, let's make n900
DT booting behave the same way for ir-rx51 as the legacy booting does.

For now, we need to pass pdata to the ir-rx51 driver. This means that
the n900 tree can move to using DT based booting without having to carry
all the legacy platform data with it when it gets dropped from the mainline
tree.

Note that the ir-rx51 driver is currently disabled because of the
dependency to !ARCH_MULTIPLATFORM. This will get sorted out later
with the help of drivers/pwm/pwm-omap-dmtimer.c. But first we need
to add chained IRQ support to dmtimer code to avoid introducing new
custom frameworks.

So let's just pass the necessary dmtimer functions to ir-rx51 so we
can get it working in the following patch.

4899f78a3d mailbox/omap: drop legacy platform device support
OMAP mailbox devices can no longer be created in legacy non-DT
mode, all the relevant code has been cleaned up. The OMAP mailbox
driver will only support devices created from DT going forward,
so drop the legacy platform device support from the driver.
