f4dd029ee0 Char/Misc patches for 4.13-rc1
Here is the "big" char/misc driver patchset for 4.13-rc1.
 
 Lots of stuff in here, a large thunderbolt update, w1 driver header
 reorg, the new mux driver subsystem, google firmware driver updates, and
 a raft of other smaller things.  Full details in the shortlog.
 
 All of these have been in linux-next for a while with the only reported
 issue being a merge problem with this tree and the jc-docs tree in the
 w1 documentation area.  The fix should be obvious for what to do when it
 happens, if not, we can send a follow-up patch for it afterward.

7e87d11c9b iio: adc: Add support for TI ADC108S102 and ADC128S102
This is an upstream port of an IIO driver for the TI ADC108S102 and
ADC128S102. The former can be found on the Intel Galileo Gen2 and the
Siemens SIMATIC IOT2000. For those boards, ACPI-based enumeration is
included.

Due to the lack of regulators under ACPI, we hard-code the voltage
provided to the VA pin of the ADC to 5 V, the value used on Galileo and
IOT2000. For DT usage, the regulator "vref-supply" provides this
information. Note that DT usage has not been tested.

c6a677c6f3 Staging/IIO patches for 4.12-rc1
Here is the big staging tree update for 4.12-rc1.  And it's a big one,
 adding about 350k new lines of crap^Wcode, mostly all in a big dump of
 media drivers from Intel.  But there's other new drivers in here as
 well, yet-another-wifi driver, new IIO drivers, and a new crypto
 accelerator.  We also deleted a bunch of stuff, mostly in patch
 cleanups, but also the Android ION code has shrunk a lot, and the
 Android low memory killer driver was finally deleted, much to the
 celebration of the -mm developers.
 
 All of these have been in linux-next with a few build issues that will
 show up when you merge to your tree, I'll follow up with fixes for those
 after this gets merged.

a9e9c7153e iio: adc: add max1117/max1118/max1119 ADC driver
This adds max1117/max1118/max1119 8-bit, dual-channel ADC driver.

This new driver uses the zero length spi_transfers with the cs_change
flag set and/or the non-zero delay_usecs.

1. The zero length transfer with the spi_transfer.cs_change set is
required in order to select CH1.  The chip select line must be brought
high and low again without transfer.

2. The zero length transfer with the spi_transfer.delay_usecs > 0 is
required for waiting the conversion to be complete.  The conversion
begins with the falling edge of the chip select.  During the conversion
process, SCLK is ignored.

These two usages are unusual.  But the spi controller drivers that use
a default implementation of transfer_one_message() are likely to work.
(I've tested this adc driver with spi-omap2-mcspi and spi-xilinx)

On the other hand, some spi controller drivers that have their own
transfer_one_message() may not work.  But at least for the zero length
transfer with delay_usecs > 0, I'm proposing a new testcase for the
spi-loopback-test that can test whether the delay_usecs setting has
taken effect.

96b3c83303 iio: xoadc: augment DT bindings a bit
In order to accommodate in a logical manner for the premuxed channels
in PM8921 and the similarly addressed channels in later PMICs, we
need a twocell arrangement with premux and analog mux setting as
a tuple to uniquely identify a hardware channel.

These bindings are not yet in use, so it should be fine to augment
them before we actually start using it in drivers and device trees.

This scheme came out of lengthy discussions and reverse-engineering
and reading of the few information sources we have.

bc82222fcc iio:adc: Driver for Linear Technology LTC2497 ADC
This patch adds support for the Analog Devices / Linear Technology
LTC2497 ADCs. The LTC2497 is a 16-channel (eight differential),
16-bit, high precision, delta-sigma ADC with an automatic, differential,
input current cancellation front end and a 2-wire, I2C interface.

0c8f492dd7 iio:imu:mpu6050 add explicit mpu9250 support
The mpu9250 is a SIP containing an mpu6500 and an ak8975.  If this was all
there was too it there would be no need for explicit handling in the driver.
Arguably the bindings would also only reflect the presence of an mpu6500 with
the ak8975 hanging off it, as the kernel doesn't care that they are in one
package.

However, the WHOAMI value changes as well so best to add explicit support.

3cc17e61d4 iio:imu:mpu6050 update i2c bindings to reflect i2c-gate and supported parts
These bindings are somewhat lagging the state of the driver.  The i2c-gate
bindings are documented elsewhere, but it seems sensible to at least have
an example and cross reference in here.  SPI bindings will need to be the
subject of a future patch.

25ec249632 iio: adc: cpcap: Add minimal support for CPCAP PMIC ADC
On Motorola phones like droid 4 there is a custom CPCAP PMIC. This PMIC
has ADCs that are used for battery charging and USB PHY VBUS and ID pin
detection.

Unfortunately the only documentation for this ADC seems to be the
Motorola mapphone Linux kernel tree. I have tested that reading raw and
scaled values works, but I have not used the timed sampling that the ADC
seems to support.

Let's add a minimal support for it so we can eventually provide IIO
channels for the related battery charging and USB PHY drivers.

As part of this enablement: make us depend on the old drivers
not being in use so we don't get a kernel with two competing
