2nd set of new device support, features and cleanups for IIO in the 4.12 cycle

A good collection of outreachy related patches in here - mostly staging
driver cleanup. Also a fair number of patches added explicit OF device ID
tables for i2c drivers - a precursor to dropping (eventually) the implicit
probing.

New Device Support
* Allwinner SoC ADC.
  - So far covers the sun4i-a10, sun5i-a13 and sun6i-a31 general purpose ADCs,
  including thermal side of things.
  This missed the last cycle due to my incompetence, so good to get in now,
  particularly as various patches dependent on it are appearing.
* ltc2632
  - new driver supporting ltc2632-l12, ltc2632-l10, ltc2632-l8, ltc2632-h12,
    ltc-2632-h10, ltc-2632-h8 dacs

Cleanups
* Documentation
  - drop a broken reference to i2c/trivial-devices
* ad2s1200
  - drop & from function pointers for consistency.
* ad2s1210
  - formatting fixes.
* ad7152
  - octal permissions instead of symbolic.
  - drop & from function pointers for consistent usage.
* ad7192
  - drop & from function pointers for consistent usage.
* ad7280
  - replace core mlock usage with a local lock as mlock is intended only to
  protect the current device state (direct reads, or triggered and buffered)
* ad7746
  - drop & from function pointers for consistent usage.
  - replace core mlock usage with a local lock as mlock is intended only to
  protect the current device state (direct reads, or triggered and buffered)
* ad7754
  - move contents of header file into source file as not used anywhere else.
* ad7759
  - move contents of header file into source file as not used anywhere else.
* ad7780
  - drop & from function pointers for consistent usage.
* ad7832
  - replace core mlock usage with a local lock as mlock is intended only to
  protect the current device state (direct reads, or triggered and buffered)
* ad9834
  - replace core mlock usage with a local lock as mlock is intended only to
  protect the current device state (direct reads, or triggered and buffered)
  - drop an unnecessary goto in favour of direct return.
* adis16060
  - drop & from function pointers as inconsistent.
* adis16201
  - drop a local mutex as the adis core already protects everything necessary.
  - drop & from function pointers for consistent usage.
* adis16203
  - drop & from function pointers for consistent usage.
* adis16209
  - drop a local mutex as the adis core already protects everything necessary.
  - use an enum for scan index giving slightly nicer code.
  - drop & from function pointers for consistent usage.
* adis16240
  - drop a local mutex as the adis core already protects everything necessary.
  - use an enum for scan index giving slightly nicer code.
  - drop & from function pointers for consistent usage.
* apds9960
  - add OF device ID table.
* bma180
  - add OF device ID table.
  - prefer unsigned int to bare use of unsigned.
* bmc150_magn
  - add OF device ID table.
* hmp03
  - add OF device ID table.
* ina2xx
  - add OF device ID table.
* itg3200
  - add OF device ID table.
* mag3110
  - add OF device ID table.
* max11100
  - remove .owner field as it is set by the spi core.
* max5821
  - add .of_match_table set to the ID table which was present but not used.
* mcp4725
  - add OF device ID table.
* mlx96014
  - add OF device ID table.

* mpu6050
  - add OF device ID table.
* pc104
  - mask pc104 drivers behind a global pc104 config option.
* ti-ads1015
  - add OF device ID table.

  - add OF device ID table.
* us5182d
  - add OF device ID table.

Linear Technology LTC2632 DAC device driver



Required properties:

 - compatible: Has to contain one of the following:

	lltc,ltc2632-l12

	lltc,ltc2632-l10

	lltc,ltc2632-l8

	lltc,ltc2632-h12

	lltc,ltc2632-h10

	lltc,ltc2632-h8



Property rules described in Documentation/devicetree/bindings/spi/spi-bus.txt

apply. In particular, "reg" and "spi-max-frequency" properties must be given.



Example:



	spi_master {

		dac: ltc2632@0 {

			compatible = "lltc,ltc2632-l12";

			reg = <0>; /* CS0 */

			spi-max-frequency = <1000000>;

		};

	};
