[PATCH 0/3] Subject: [PATCH v1 0/3] iio: dac: Add support for MAX22007 DAC

[Janani Sunil <janani.sunil@analog.com>]

This patch series introduces support for the Analog Devices MAX22007, a
quad-channel, 12-bit digital-to-analog converter (DAC) with integrated
precision output amplifiers and configurable voltage/current output capability.

**Device Overview:**
The MAX22007 features four independent DAC channels that can each be configured
for either voltage output (0-12.5V) or current output (0-25mA) mode. The device
communicates via SPI interface with built-in CRC8 error checking for data integrity.

**Features Implemented:**
- Support for all 4 DAC channels with 12-bit resolution
- Per-channel voltage/current mode configuration via device tree
  property `adi,type = [voltage, current]`
- Independent power control for each channel (attribute)
- Hardware reset support via GPIO (during probe)
- CRC8 error checking for SPI communication

**Patch Summary:**
1. dt-bindings: Binding documentation with channel configuration
2. documentation: Driver documentation with usage examples
3. driver: Implement IIO DAC driver

**Testing:**
The driver was hardware tested on a Raspberry Pi4 on top of v6.12.y
kernel using the MAX22007EVKIT evaluation board.
