   4 Subject: [PATCH 079/117] dt-bindings: thermal: sun8i: Add compatible for D1
   5
   6 D1 contains a thermal sensor similar to other Allwinner SoCs. Like the
   7 H3 variant, it contains only one channel.
   8
   9 D1's thermal sensor gets a reference voltage from AVCC. This may always
  10 have been the case; it is explicitly documented in the SoC user manuals
  11 since at least H616. However, it was not as important on earlier SoCs,
  12 because those reference designs foreced AVCC always-on by connecting it
  13 to the PLL power supply.
  14
  15 Now, since D1 only uses AVCC for other optional peripherals, this supply
  16 could be turned off at runtime, so it must be made explicit in the DTS.
