[PATCH v1 0/3] meson saradc: add iio channels to read channel 7 mux inputs

[George Stark]

From: George Stark <GNStark at sberdevices.ru>

In meson saradc channel7 is connected to muxer which allows to measure
inner sources like Vdd, GND, several Vdd dividers. This patch series
adds independent iio channel (with label) for every chan7 mux input.
Mux switch is handled transparent for clients.
This functionality can help debug\test\calibrate adc.
This code is relevant for all supported amlogic soc families

This patch series was created after discussion [1], [2]
