iio: adc: add max11205 adc driver

2022-09-05T17:08:34Z

Adding support for max11205 16-bit single-channel ultra-low power delta-sigma adc. The MAX11205 is compatible with the 2-wire interface and uses SCLK and RDY/DOUT for serial communications. In this mode, all controls are implemented by timing the high or low phase of the SCLK. The 2-wire serial interface only allows for data to be read out through the RDY/DOUT output.

iio: adc: qcom-spmi-rradc: introduce round robin adc

2022-06-18T13:14:29Z

The Round Robin ADC is responsible for reading data about the rate of charge from the USB or DC input ports, it can also read the battery ID (resistence), skin temperature and the die temperature of the pmic. It is found on the PMI8998 and PM660 Qualcomm PMICs. Signed-off-by: Caleb Connolly Link: https://lore.kernel.org/r/20220429220904.137297-6-caleb.connolly@linaro.org Signed-off-by: Jonathan Cameron

iio:adc:ad7280a: Move out of staging

2022-02-21T19:33:05Z

This is a rather unusual device (in IIO anyway). However, it has a near to standard userspace ABI. Note the work to move this out of staging was done against a minimal QEMU model, which doesn't model all the features of the device. I have no intention to upstream the QEMU model as it was developed just to enable this driver cleanup. https://github.com/jic23/qemu/tree/ad7280a-hacks Signed-off-by: Jonathan Cameron Reviewed-by: Marcelo Schmitt Link: https://lore.kernel.org/r/20220206190328.333093-21-jic23@kernel.org

iio: adc: Add Xilinx AMS driver

2021-12-21T15:10:09Z

The AMS includes an ADC as well as on-chip sensors that can be used to sample external voltages and monitor on-die operating conditions, such as temperature and supply voltage levels. The AMS has two SYSMON blocks. PL-SYSMON block is capable of monitoring off chip voltage and temperature. PL-SYSMON block has DRP, JTAG and I2C interface to enable monitoring from an external master. Out of these interfaces currently only DRP is supported. Other block PS-SYSMON is memory mapped to PS. The AMS can use internal channels to monitor voltage and temperature as well as one primary and up to 16 auxiliary channels for measuring external voltages. The voltage and temperature monitoring channels also have event capability which allows to generate an interrupt when their value falls below or raises above a set threshold.

iio: adc: add ADC driver for the TI TSC2046 controller

2021-05-17T12:49:11Z

Basically the TI TSC2046 touchscreen controller is 8 channel ADC optimized for the touchscreen use case. By implementing it as an IIO ADC device, we can make use of resistive-adc-touch and iio-hwmon drivers. Polled readings are currently not implemented to keep this patch small, so iio-hwmon will not work out of the box for now. So far, this driver was tested with a custom version of resistive-adc-touch driver, since it needs to be extended to make use of Z1 and Z2 channels. The X/Y are working without additional changes.
