This series adds support for Allwinner D1/T113s thermal sensor controller.
THIS controller is similar to the one on H6, but with only one sensor and
uses a different scale and offset values.

v6:
- Rebased onto 6.7.0-rc5

v5:
- Dropeed 'thermal-zones' node from sunxi-d1s-t113.dtsi

v4:
- Dropeed DT bindings example

v3:
- Fixed SoB tag again

v2:
- Fixed SoB tag
- Moved binding patch before driver changes

v1:
- Initial version

Maxim Kiselev (3):
  dt-bindings: thermal: sun8i: Add binding for D1/T113s THS controller
  thermal: sun8i: Add D1/T113s THS controller support
  riscv: dts: allwinner: d1: Add thermal sensor

Any reason this is disabled? We typically don't disable those internal
devices in the SoC .dtsi, the THS is one example (check the instances
in other SoCs' .dtsi files).

The rest looks alright, compared to the manual, so with this line
removed:
