Pull i2c updates from Wolfram Sang:
"Here is the I2C pull request for 4.8:
- the core and i801 driver gained support for SMBus Host Notify
- core support for more than one address in DT
- i2c_add_adapter() has now better error messages. We can remove all
error messages from drivers calling it as a next step.
- bigger updates to rk3x driver to support rk3399 SoC
- the at24 eeprom driver got refactored and can now read special
variants with unique serials or fixed MAC addresses.
The rest is regular driver updates and bugfixes"

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"

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.

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.

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).

- 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.

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.

If the line is set to be open drain, also tag on IRQF_SHARED

point of using open drain interrupt lines is to share them with
