c02b7bf532 i2c: mux: mellanox: add driver
This driver allows I2C routing controlled through CPLD select registers on
a wide range of Mellanox systems (CPLD Lattice device).
MUX selection is provided by digital and analog HW. Analog part is not
under SW control.
Digital part is under CPLD control (channel selection/de-selection).

Connectivity schema.
.---.             .-------------.
| l |             |             |-- i2cx1 -- i2cx8
| i |-- i2cn --+--| mlxcpld mux |
| n |          |  |             |-- i2cy1 -- i2cy8
| u |          |  '-------------'
| x |          |         |
'---'          '---------'

i2c-mux-mlxpcld does not necessarily require i2c-mlxcpld. It can be used
along with another bus driver, and still control i2c routing through CPLD
mux selection, in case the system is equipped with CPLD capable of mux
selection control.

The Kconfig currently controlling compilation of this code is:
drivers/i2c/muxes/Kconfig:config I2C_MUX_MLXCPLD

d52ea7e3d4 MAINTAINERS: Add drm-misc
KS happened, time to make this official!

Well, scripting work to make this all happen is still ongoing, but I'm
trying to at least keep the new tree semi-in-sync with the temporary
topic/drm-misc branch in the drm-intel.git repo. So for now still no
new committers, and existing ones still need to push to topic/drm-misc
in drm-intel.git.

Big kudos to Jani&Sean for volunteering as co-maintainers!

v2: Restrict patterns a bit to avoid all the driver spam.

2c52b1efd6 Third set of IIO new device support, features and cleanup for the 4.10 cycle.
Includes Peter Rosin's interesting drivers for a comparator. First complex
 use we have had with an analog front end made from discrete components.
 
 Brian Masney's work on moving the tsl2583 driver out of staging also
 feature extensively!
 
 New Drivers
 * DAC based on a digital potentiometer
   - New driver for the use of a dpot as a DAC. Includes bindings and Axentia
   entry in vendor prefixes.
 * Envelope detector baed on DAC and a comparator including device tree
   bindings.
 
 Staging Graduation
 * tsl2583.
 
 Core new features
 - Core provision for _available attributes.   This one had been stalled for
   a long time until Peter picked it up and ran with it!
 - In kernel interface helpers to retrieve available info from channels.
 
 Driver new features
 * mcp4531
   - Add range of available raw values (used for the dpot dac driver).
 
 Driver cleanups and fixes for issues introduced
 * ad7766
   - Testing the wrong variable following devm_regulator_bulk_get introduced
   with the driver earlier in this cycle.
 * ad9832
   - Fix a wrong ordering in the probe introduced in the previous set of
     patches.  A use before allocation bug.
 * cros_ec_sensors
   - Testing for an error in a u8 will never work.
 * mpu3050
   - Remove duplicate initializer for the module owner.
   - Add missing i2c dependency.
   - Inform the i2c mux core how it is used - step one in implifying device
   tree bindings.
 * st-sensors
   - Get rid of large number of uninformative defines in favour of putting the
   constants where they are relevant. It is clear what they are from where
   they are used.
 * tsl2583
   - Fix unused function warning when CONFIG_PM disabled and remove the
   ifdefs in favour of __maybe_unused.
   - Refactor taos_chip_on  to only read relevant registers.
   - Make sure calibscale and integration time are being set.
   - Verify chip is in ready to be used before calibration.
   - Remove some repeated checks for chip status (it's protected by a mutex
   so can't change until it's released)
   - Change current state storage from a tristate enum to a boolean seeing as
   only two values are actually used now.
   - Drop a redundant write to the control regiser in taos_probe (it's a noop)
   - Drop the FSF mailing address.
   - Clean up logging to not use hard coded function names (use __func__
   instead).
   - Cleanup up variable and function name prefixes.
   - Alignment of #define fixes.
   - Fix comparison between signed and unsigned integer warnings.
   - Add some newlines in favour of readability.
   - Combine the two sysfs ABI docs that somehow ended up in different places.
   - Fix multiline comment syntax.
   - Move a code block to inside an else statement as it makes more sense there.
   - Change tsl2583_als_calibrate to return 0 rather than a value nothing
   reads.
   - Drop some pointless brackets
   - Don't assume 32bit unsigned int.
   - Change to a per device instance lux table.
   - Add missing tsl2583 to the list of supported devices in the intro comments.
   - Improve commment on clearing of interrupts.
   - Drop some uninformative comments.
   - Drop a memset call that doesn't do anything useful any more.
   - Don't initialize some return variables that are always set.
   - Add Brian Masney as a module author after all these changes.

Note that the touchpad two-finger support is fairly unreliable,

 9) Fix SCTP reference counting of associations and transports in

f2ed287bcc char/pcmcia: add scr24x_cs chip card interface driver
This implements only the very basic protocol "Mode A", just to make the
device functional. Patches to implement "Mode C" that uses better bulking
and is interrupt-driver may follow.

The device essentially speaks the same protocol as USB CCID devices do over
the bulk endpoints. The driver exchanges the command submissions and
responses over a plain read()/write() interface, compatible with legacy
OpenCT's pcmcia_block driver.

Patches for the newer CCID driver are available:

7970b9e6a5 Second round of new device support, cleanups and fixes for IIO in the 4.10 cycle
This includes two branch merges for elements that may also go via MFD.
 
 New device support
 * cros_ec
   - new driver to support these Chrome OS contiguous sensors which are behind
     the Chrome OS embedded controller.  Requires a few minor MFD and chrome
     platform changes.  One follow up fix deals with some dependency issues in
     Kconfig.
 * mpu-3050
   - new driver and device tree bindings for this venerable device.
 * st_accel
   - support for the lng2dm an
 
 Driver features
 * ad7192
   - Add DVdd regulator handling
 * ad9832
   - Add DVDD regulator handling
 * at91
   - Suspend and resume support
 * si7020
   - Device tree bindings
 * ti-am335x
   - DMA support - uses dma to accelerate short bursts of read back rather
   than full blown DMA buffer support.  Greatly improved performance.
   Includes an MFD addition to give access to the address needed for DMA.
 * tsl2583
   - Device tree bindings
 
 Cleanups and minor fixes
 * ad7192
   - Fix regulator naming to match datasheet
   - Handle regulator errors correctly (so as to not break deferred probing)
   - Rename reg variable to reflect which regulator it is
 * ad5933
   - Fix regulator naming to match datasheet
   - Handle regulator errors correctly (so as to not break deferred probing)
 * ad7746
   - Fix a missing return value (fallout from previous patch set)
 * ad7780
   - Fix regulator naming to match datasheet
   - Handle regulator errors correctly (so as to not break deferred probing)
 * ad9832
   - Fix regulator naming to match datasheet
   - Handle regulator errors correctly (so as to not break deferred probing)
   - Rename reg regulator to reflect which one it is
 * ad9834
   - Fix regulator naming to match datasheet
   - Handle regulator errors correctly (so as to not break deferred probing)
 * hts221
   - Remove a duplicated include
 * maxim thermocouple
   - Handle a wrong storage side in read function.  Prevent any problems that
   might be introduced by additions to this driver in future.
 * tsl2583 - big set from Brian Masney to drive this towards a staging
   graduation.
   - Convert to iio_chan_spec and read_raw / write_raw (in a couple of steps)
   - Improved error handling in various functions
   - Drop redundant power_state custom sysfs attribute.
   - Use IIO_*_ATTR* macros for remaining attributes.
   - Return an error code to userspace on invalid parameters being writen to
     sysfs files.
   - Add locking to various attribute accesses to remove possible races.
   - Add defines for various magic numbers.
   - Use smbus_read_byte_data instead of a write_byte followed by read_byte.
   - Query only relevant registers in probe.
   - Tidy up ordering of code comments.
   - Remove a pointless power off sequence in taos_chip_on.
   - Don't bother shutting down the chip when updating the lux table.
   The table is held entirely in the driver and doesn't effect the chip at all.
   - Drop a redundant i2c call in taos_als_calibrate where the same register
   is read twice in a row.
