iio: adc: Add support for STM32 ADC

2016-11-19T12:18:33+00:00

This patch adds support for STMicroelectronics STM32 MCU's analog to digital converter. Signed-off-by: Fabrice Gasnier Signed-off-by: Jonathan Cameron

iio: adc: Add support for STM32 ADC core

2016-11-19T12:17:45+00:00

Add core driver for STMicroelectronics STM32 ADC (Analog to Digital Converter). STM32 ADC can be composed of up to 3 ADCs with shared resources like clock prescaler, common interrupt line and analog reference voltage. This core driver basically manages shared resources.

iio: envelope-detector: ADC driver based on a DAC and a comparator

2016-11-13T13:07:17+00:00

The DAC is used to find the peak level of an alternating voltage input signal by a binary search using the output of a comparator wired to an interrupt pin. Like so: _ | \ input +------>-------|+ \ | \ .-------. | }---. | | | / | | dac|-->--|- / | | | |_/ | | | | | | | | irq|------<-------' | | '-------' Signed-off-by: Peter Rosin Acked-by: Thomas Gleixner Signed-off-by: Jonathan Cameron

iio:adc: Add support for AD7766/AD7767

2016-09-27T19:33:01+00:00

Add support for the AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1, AD7767-2 Analog to Digital converters. It's a family of single channel 24-bit SAR ADCs. They are all digital interface compatible and the main difference is the internal decimation rate and analog performance. For communication with the host processor a SPI interface is used. In addition the part has a data ready pin that is pulsed for one MCLK cycle when a conversion has completed and can be used as a IIO trigger.

iio: stx104: Add IIO support for the ADC channels

2016-09-03T16:25:53+00:00

The Apex Embedded Systems STX104 features 16 channels of single-ended (8 channels of true differential) 16-bit analog input. Differential input configuration may be selected via a physical jumper on the device. Similarly, input polarity (unipolar/bipolar) is configured via a physical jumper on the device. Input gain selection is available to the user via software, thus allowing eight possible input ranges: +-10V, +-5V, +-2.5V, +-1.25V, 0 to 10V, 0 to 5V, 0 to 2.5V, and 0 to 1.25V. Four input gain configurations are supported: x1, x2, x4, and x8. This ADC resolution is 16-bits (1/65536 of full scale). Analog input samples are taken on software trigger; neither FIFO sampling nor interrupt triggering is supported by this driver. The Apex Embedded Systems STX104 is primarily an analog-to-digital converter device. The STX104 IIO driver was initially placed in the DAC directory because only the DAC portion of the STX104 was supported at the time. Now that ADC support has been added to the STX104 IIO driver, the driver should be moved to the more appropriate ADC directory. Signed-off-by: William Breathitt Gray Signed-off-by: Jonathan Cameron

iio: adc: add ADC12130/ADC12132/ADC12138 ADC driver

2016-08-31T17:10:36+00:00

This adds Texas Instruments' ADC12130/ADC12132/ADC12138 12-bit plus sign ADC driver. I have tested with the ADC12138. The ADC12130 and ADC12132 are not tested but these are similar to ADC12138 except that the mode programming instruction is a bit different.

iio: adc: ltc2485: add support for Linear Technology LTC2485 ADC

2016-08-29T15:57:40+00:00

Adds basic support for the LTC2485 ADC - a delta-sigma analog-to-digital converter with an I2C interface that operates in single shot conversion mode. The driver supports an on board 5V reference and the power-on default configuration which rejects both 50hz & 60hz line frequencies and operates in 1x speed mode.

iio: adc: mt2701: Add Mediatek auxadc driver for mt2701.

2016-08-21T18:54:30+00:00

Add Mediatek auxadc driver based on iio. It will register a device in iio and support iio. So thermal can read auxadc channel to sample data by iio device. It is tested successfully on mt2701 platform. Mt8173 and mt6577 platforms are not tested. But the expectation is compatible. Signed-off-by: Zhiyong Tao Signed-off-by: Jonathan Cameron

iio: adc: ti-adc161s626: add support for TI 1-channel differential ADCs
