+description: |
+  This ADC is often used to provide channels via the io-channels
+  consumer framework.
+  Channels list:
+    0 battery type
+    1 battery temp NTC (optional current source)
+    2 GP
+    3 temp (with ext. diode, optional current source)
+    4 GP
+    5 GP
+    6 VBAT_SENSE
+    7 VCC_SENSE
+    8 Backup Battery voltage
+    9 external charger (VCHG)
+    10 VBUS
+    11 DC-DC current probe (how does this work?)
+    12 internal die temp
+    13 internal die temp
+    14 USB ID pin voltage
+    15 test network
