2026-01-11iio: adc: Initial support for AD4134Marcelo Schmitt
AD4134 is a 24-bit, 4-channel, simultaneous sampling, precision analog-to-digital converter (ADC). The device can be managed through SPI or direct control of pin logical levels (pin control mode). The AD4134 design also features a dedicated bus for ADC sample data output. Though, this initial driver for AD4134 only supports usual SPI connections. Add basic support for AD4134 that enables single-shot ADC sample read.
