Merge tag 'staging-4.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging and IIO updates from Greg KH:
 "Here are the big staging/iio patches for 4.19-rc1.

  Lots of churn here, with tons of cleanups happening in staging
  drivers, a removal of an old crypto driver that no one was using
  (skein), and the addition of some new IIO drivers. Also added was a
  "gasket" driver from Google that needs loads of work and the erofs
  filesystem.

  Even with adding all of the new drivers and a new filesystem, we are
  only adding about 1000 lines overall to the kernel linecount, which
  shows just how much cleanup happened, and how big the unused crypto
  driver was.

  All of these have been in the linux-next tree for a while now with no
  reported issues"

Contact: linux-iio@vger.kernel.org
Description:
The sensor is able to perform correction of distance
measurements due to changing temperature and ambient
light conditions. It can be programmed to correct for
a second order error polynomial.
Phase data has to be collected when temperature and
ambient light are modulated independently.
Then a least squares curve fit to a second order
polynomial has to be generated from the data. The
resultant curves have the form ax^2 + bx + c.
From those two curves, a and b coefficients shall be
stored in in_proximity0_calib_phase_temp_a and
in_proximity0_calib_phase_temp_b for temperature and
in in_proximity0_calib_phase_light_a and
in_proximity0_calib_phase_light_b for ambient light.
Those values must be integer in [0; 8355840] range.
Finally, the c constant is set by the sensor
internally.
The value stored in sensor is displayed when read from.

Required properties:
- adi,dc-dc-mode: Mode of operation of the dc-to-dc converter
Dynamic Power Control (DPC)
In this mode, the AD5758 circuitry senses the output
voltage and dynamically regulates the supply voltage,

headroom voltage for the output buffer.
Programmable Power Control (PPC)
In this mode, the VDPC+ voltage is user-programmable to
a fixed level that needs to accommodate the maximum output
load required.
The output of the DAC core is either converted to a
current or voltage output at the VIOUT pin. Only one mode
can be enabled at any one time.
The following values are currently supported:
* 1: DPC current mode
* 2: DPC voltage mode
* 3: PPC current mode
Depending on the selected output mode (voltage or current) one of the
two properties must
be present:
- adi,range-microvolt: Voltage output range
The array of voltage output ranges must contain two fields:
* <0 5000000>: 0 V to 5 V voltage range
* <0 10000000>: 0 V to 10 V voltage range
* <(-5000000) 5000000>: ±5 V voltage range
* <(-10000000) 10000000>: ±10 V voltage range
- adi,range-microamp: Current output range
The array of current output ranges must contain two fields:
* <0 20000>: 0 mA to 20 mA current range
* <0 24000>: 0 mA to 24 mA current range
* <4 24000>: 4 mA to 20 mA current range
* <(-20000) 20000>: ±20 mA current range
* <(-24000) 24000>: ±24 mA current range
* <(-1000) 22000>: −1 mA to +22 mA current range
Optional properties:
- adi,dc-dc-ilim-microamp: The dc-to-dc converter current limit
The following values are currently supported [uA]:
* 150000
* 200000
* 250000
* 300000
* 350000
* 400000
- adi,slew-time-us: The time it takes for the output to reach the
full scale [uS]
The supported range is between 133us up to 1023984375us

Generic resistive touchscreen ADC
Required properties:
- compatible: must be "resistive-adc-touch"
The device must be connected to an ADC device that provides channels for
position measurement and optional pressure.
Refer to ../iio/iio-bindings.txt for details
- iio-channels: must have at least two channels connected to an ADC device.
These should correspond to the channels exposed by the ADC device and should
have the right index as the ADC device registers them. These channels
represent the relative position on the "x" and "y" axes.
- iio-channel-names: must have all the channels' names. Mandatory channels
are "x" and "y".
Optional properties:
- iio-channels: The third channel named "pressure" is optional and can be
used if the ADC device also measures pressure besides position.
If this channel is missing, pressure will be ignored and the touchscreen
will only report position.
- iio-channel-names: optional channel named "pressure".
Example:
resistive_touch: resistive_touch {
compatible = "resistive-adc-touch";
touchscreen-min-pressure = <50000>;
io-channels = <&adc 24>, <&adc 25>, <&adc 26>;

Say yes here to build support for Bosch Sensortec BME680 sensor with
temperature, pressure, humidity and gas sensing capability.
This driver can also be built as a module. If so, the module for I2C
would be called bme680_i2c and bme680_spi for SPI support.
