This series implements driver for Sophgo cv180x/sg200x on-chip thermal
sensor and adds thermal zones for CV1800B SoCs.

Changed from v3:
1. style improvments
2. drop unnecessary dt parameters for simplicity

Changed from v2:
1. style and code improvements
2. use human-readable value for sensor parameters

Changed from v1:
1. style and code improvements
2. make sample parameters configurable
3. generalize document temperature calculating formula

  dt-bindings: thermal: sophgo,cv1800-thermal: Add Sophgo CV1800 thermal
  riscv: dts: sophgo: cv18xx: Add sensor device and thermal zone
  thermal: cv180x: Add cv180x thermal driver support
