2014-01-22Check null pointers for sysfs callsStefan Agner
When grepping through sysfs, grep tries to read all sysfs files which are available. Some of them lead to error due to null pointers. Therefor check for null pointers before using them.
2013-12-09iio: adc: add STMPE ADC driver using IIO frameworkStefan Agner
This adds an ADC driver for the STMPE device using the industrial input/output interface. The driver supports raw reading of values. The driver depends on the MFD stmpe driver. If the touchscreen block is enabled too, only for of the 8 ADC channels are available.

2011-06-28iio: light sensor: Add SMBUS support to the tsl2563 driver.Bryan Freed
This is so we can support it on x86 SMBUS adapters. Since i2c adapters which do not provide an smbus_xfer interface fall back to using their I2C master_xfer interface, all the i2c_master_send() calls in this driver are changed to i2c_smbus_*() calls. This will fail on an i2c adapter that implements a proper subset of (SMBUS_BYTE | SMBUS_BYTE_DATA | SMBUS_WORD_DATA), but I do not see that in any of our adapters today. This results in a few wrapper functions that provide little additional functionality, so remove them and call the smbus functions directly from the general driver code.

New driver for AD7792/AD7793 3-Channel, Low Noise, Low Power, 16-/24-Bit Sigma-Delta ADC with On-Chip In-Amp and Reference. The AD7792/AD7793 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: Use bool where applicable. Use data buffer that lives in their own cache line. Restructure ad7793_calibrate_all to use an array. Use msleep. Query REG_ID instead of doing a write/read This is a test. Add support for unipolar mode. Drop range attribute in favor of write scale. Add proper locking. Use new validate_trigger callbacks. Use IIO_IN_DIFF for differential channels. Change attribute naming. Use available_scan_masks. Some other miscellaneous cleanup (none functional changes).
