This is the second series of three on updating the AD5686 driver. Initially, a big patch series was sent: https://lore.kernel.org/r/[email protected]
Then, the first patch series added fixes and cleanups: https://lore.kernel.org/linux-iio/[email protected]/ This one is introducing new features: - Consume optional reset and correct 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.
