[PATCH 0/3] hwmon: (adt7410): Add ADT7422 support

[Nuno Sá via B4 Relay]

The main goal is to add support for the ADT7422 digital temperature
sensor which is similar to the ones already supported by the adt7410
driver.

While on it add the devices to trivial-devices and a proper of_id
table.

[PATCH 2/3] hwmon: (adt7410): Add OF match table

[Nuno Sá via B4 Relay]

From: Nuno Sá <nuno.sa@analog.com>

Add a struct of_device_id match table to the driver.

While at it, make sure to properly include mod_devicetable.h which is
also needed for struct i2c_device_id.

[PATCH 3/3] hwmon: (adt7410): Support adt7422 chip

[Nuno Sá via B4 Relay]

From: Nuno Sá <nuno.sa@analog.com>

Add support for the ADT7422 high accuracy digital temperature sensor. It's
identical to the other chips supported in the driver so we just need to
add it to the ID tables.
