This series adds support for multiple nanoDAC parts, adding triggered buffer and gain control support to the ad5686 DAC driver family, along with a number of driver cleanups and fixes.
Initial patches update the device-tree bindings: - Add compatible entries for missing and new parts; - Add GPIO properties for RESET, GAIN and LDAC pins; - Add missing power supplies properties. Driver cleanups and fixes: - Refactor include headers (IWYU); - Switch to device managed mutex initialization; - Drop enum chip id in favor of per-device chip_info structs; - Fix voltage reference control on single-channel devices; - Fix powerdown control on dual-channel devices; - Introduce bus ops struct with a sync() operation for batching bus transfers. New functionality: - Device support for: AD5316R, AD5675, AD5697R, AD5313R, AD5317R, AD5674, AD5679, AD5687, AD5687R, AD5689 and AD5689R; - Consume optional reset and new power supplies; - LDAC GPIO handling (active-low, held low when unused); - SPI bus sync() implementation for batching multiple transfers; - Triggered buffer support, leveraging LDAC and sync() to flush all channel writes atomically; - Gain control support through the scale property.
