Patch 1 describes the three LTC2305 ADCs fitted on Ventura2 and exposes the valve voltages read by the bus 3 ADCs through iio-hwmon. The LTC2305 ADCs use their internal 4.096V reference, so no vref-supply is described. Patch 1 therefore depends on "dt-bindings: iio: adc: ltc2497: Make vref-supply optional for LTC2305/LTC2309"; without it, dtbs_check reports a missing vref-supply for the LTC2305 nodes. Patch 2 names the presence detect GPIO of the optional COM Express module so userspace can determine whether the module is present. Patch 3 names the reset GPIOs of the three USB-to-UART bridges so userspace can reset the bridges.
