iio: adc: adding support for MCP3564 ADC

2023-09-12T09:42:04+00:00

This is the iio driver for Microchip family of 153.6 ksps, Low-Noise 16/24-Bit Delta-Sigma ADCs with an SPI interface (Microchip's MCP3461, MCP3462, MCP3464, MCP3461R, MCP3462R, MCP3464R, MCP3561, MCP3562, MCP3564, MCP3561R, MCP3562R and MCP3564R analog to digital converters).

iio: adc: add ltc2309 support

2023-09-12T09:42:04+00:00

The LTC2309 is an 8-Channel, 12-Bit SAR ADC with an I2C Interface. This implements support for all single-ended and differential channels, in unipolar mode only. Signed-off-by: Liam Beguin Link: https://lore.kernel.org/r/20230828-ltc2309-v3-2-338b3a8fab8b@gmail.com Signed-off-by: Jonathan Cameron

iio: adc: Add Allwinner D1/T113s/R329/T507 SoCs GPADC

2023-07-20T18:21:29+00:00

The General Purpose ADC (GPADC) can convert the external signal into a certain proportion of digital value, to realize the measurement of analog signal, which can be applied to power detection and key detection. Theoretically, this ADC can support up to 16 channels. All SoCs below contain this GPADC IP. The only difference between them is the number of available channels: T113 - 1 channel D1 - 2 channels R329 - 4 channels T507 - 4 channels Reviewed-by: Andy Shevchenko Signed-off-by: Maksim Kiselev Link: https://lore.kernel.org/r/20230619154252.3951913-3-bigunclemax@gmail.com Signed-off-by: Jonathan Cameron

iio: adc: add ADC driver for the TI LMP92064 controller

2022-12-28T17:19:44+00:00

The TI LMP92064 is a dual 12 Bit ADC connected via SPI. The two channels are intended for simultaneous measurements of the voltage across- and current through a load to allow accurate instantaneous power measurements. The driver does not yet take advantage of this feature, as buffering is not yet implemented.
