hwmon: (ltc4245) Expose all GPIO pins as analog voltages
Add support for exposing all GPIO pins as analog voltages. Though this is not an ideal use of the chip, some hardware engineers may decide that the LTC4245 meets their design requirements when studying the datasheet. The GPIO pins are sampled in round-robin fashion, meaning that a slow reader will see stale data. A userspace application can detect this, because it will get -EAGAIN when reading from a sysfs file which contains stale data. Users can choose to use this feature on a per-chip basis by using either platform data or the OF device tree (where applicable). Signed-off-by: Ira W. Snyder <> Signed-off-by: Jean Delvare <>
