This is the second series of three on updating the AD5686 driver.
Initially, a big patch series was sent:
https://lore.kernel.org/r/20260422-ad5313r-iio-support-v1...
Then, the first patch series added fixes and cleanups:
https://lore.kernel.org/linux-iio/20260524-ad5686-fixes-v...
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.
