Noah Watkins efd54f4375 staging: zram: make global var "num_devices" use unique name
The global variable "num_devices" is too general to be
global. This patch switches the name to be "zram_num_devices".

Michael Hennerich 7a27b042f9 IIO: ADC: New driver for AD7190/AD7192/AD7195 4 Channel SPI ADC
New driver for AD7190/AD7192/AD7195 4.8 kHz, Ultralow Noise, 24-Bit
Sigma-Delta ADC with PGA

These devices features a dual use data out ready DOUT/RDY output.
In order to avoid contentions on the SPI bus, it's necessary to use
spi bus locking. The DOUT/RDY output must also be wired to an
interrupt capable GPIO.

In INDIO_RING_TRIGGERED mode, this driver may block its SPI bus segment
for an extended period of time.

Changes since V1:

Add missing documentation.
Remove obsoleted include files.
Fix typos and style issues.
Fix buffer size.
Split ad7192_show() into two functions.
Avoid race condition add mutex.
Abandon IIO_CHAN macro.
Reorder elements in ad7192_platform_data.
Remove driver bus type.

Michael Hennerich f94aa354d6 iio: impedance-analyzer: New driver for AD5933/4 Impedance Converter, Network Analyzer
The AD5933 is a high precision impedance converter system solution
that combines an on-board frequency generator with a 12-bit, 1 MSPS,
analog-to-digital converter (ADC). The frequency generator allows an
external complex impedance to be excited with a known frequency.

The response signal from the impedance is sampled by the on-board ADC
and a discrete Fourier transform (DFT) is processed by an on-chip DSP engine.
The DFT algorithm returns a real (R) and imaginary (I) data-word at each
output frequency.

Changes since V1:

Apply list review feedback:
Consistently use poll_time_jiffies.
Use be|le cpu endian helpers where applicable.
Add various comments.

Changes since V2:

Fix KernelVersion tag in Documentation.
Declare ad5933_default_pdata static.

Jonathan Cameron 694e1b5f95 staging:iio:magnetometer:ak8975 convert to iio_chan_spec + cleanups.
iio_chan_spec conversion is straight forward.

Other changes:
* use i2c_smbus_write_byte_data in write_data
* c99 isms to setup various structures.
* move the comment about the scale factor and kill off trivial access func.
* make mode setting code use a bool rather than a ulong.

Ultimately I'd like to get rid of that mode bit entirely and handle it through
core pm routines, but have left it for now.
