2011-07-05staging: iio: light sensor: Add a calibscale file to the isl29018 light ↵Bryan Freed
sensor driver. Defaulting to 1, this gives a way to amplify the lux value before being reduced by the programmed adc_bit shift. Only support whole numbers right now. When this driver is converted to the new IIO_CHAN framework, it will be easy to support the framework's pseudo float. Add illuminance0_calibscale documentation to sysfs-bus-iio-light.

2011-04-25staging:iio: Add ability to allocate private data space to iio_allocate_deviceJonathan Cameron
Suggested by Arnd Bergmann. Note this will break ALL drivers that are out of mainline.

2011-04-25staging: iio: TAOS tsl258x: Device driverJon Brenner
Added suspend/resume functions. Changed attribute names to match existing where applicable and updated or documented new ABI as discussed. Changed integration time ABI from using index (0 to 3) to use actual gain values (1x,8x, etc.). Removed various unused variables, declarations, and functions. Revised code to accommodate different endianess (le16_to_cpu). Updated error return codes in various functions. Changed from mdelay to msleep after determining that longer wait would be acceptable. V5: Makefile and Kconfig cleanups by Jonathan Cameron.

2011-03-09Staging: IIO: Documentation: iio_utils: fix channel array generation.Michael Hennerich
The previous implementation flawed, in case some channels are not enabled. The sorted array would then include channel information of disabled channels, And misses the enabled ones, when the count is reached. More troublesome, the loop would not even terminate. The fix is twofold: First we skip channels that are not enabled. Then we use a tested bubble sort algorithm to sort the array. Since we already allocated exactly the number of bytes we need. We can exercise bubble sort on the original memory. In all cases I've seen, the array is already sorted, so this sort terminates immediately. Changes since V1: Fix coding style issues.

2011-02-28IIO: Documentation: iio_utils: Prevent buffer overflowMichael Hennerich
The first part of build_channel_array()identifies the number of enabled channels. Further down this count is used to allocate the ci_array. The next section parses the scan_elements directory again, and fills ci_array regardless if the channel is enabled or not. So if less than available channels are enabled ci_array memory is overflowed. This fix makes sure that we allocate enough memory. But the whole approach looks a bit cumbersome to me. Why not allocate memory for MAX_CHANNLES, less say 64 (I never seen a part with more than that channels). And skip the first part entirely.

This patch adds support for the AD7298: 8-Channel, 1MSPS, 12-Bit SAR ADC with Temperature Sensor via SPI bus. This patch replaces the existing ad7298.c driver completely.
