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