Subject: [PATCH 0/2] hwmon: adc128d818: Support operation mode 1

The ADC128D818 offers four different chip operation modes which vary in the
number and measurement types of the available input signals (see datasheet
sec. 8.4.1).

The current version of the driver only supports the default chip operation mode
(mode 0), providing seven analog values and a temperature reading.

This patch series adds support for operation mode 1 (eight analog inputs but no
temperature), selectable through the device tree attribute 'mode':

        adc1: adc128d818@1d {
                compatible = "ti,adc128d818";
                reg = <0x1d>;
                mode = /bits/ 8 <1>;
        };

The changes are transparent as 'mode' defaults to mode 0 which yields the
previous behaviour. Code has been tested on real hardware using an evaluation
board.
