[PATCH 2/3] dt-bindings: iio: adc: lltc,ltc2497: add LTC2305 support

Carlos Jones Jr posted 3 patches 2 weeks ago
There is a newer version of this series
[PATCH 2/3] dt-bindings: iio: adc: lltc,ltc2497: add LTC2305 support
Posted by Carlos Jones Jr 2 weeks ago 
Add support for the LTC2305 2-channel, 12-bit ADC to the existing
LTC2497 device tree bindings. The LTC2305 is compatible with the
LTC2309 driver implementation.

Clearly this is not true, given the driver patches in the series.
