[PATCH v6 0/5] Allwinner: A523: add support for A523 THS0/1 controllers

This patch series adds temperature sensor support for the Allwinner A523
family of processors (same die with H728/A527/T527)

Based on 7.3-rc2.

Changes v6~v5:
1) dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
 - removed the redundant clocks constraint for the A523 controllers
 - simplified the else branch to maxItems: 1
 - dropped the extra example node

2) thermal/drivers/sun8i: replace devm_reset_control_get to...
 - no changes

3) thermal/drivers/sun8i: get calibration data from two nvmem cells
 - skip calibration instead of passing a NULL pointer to the calibration
   callback when no calibration cell is found

4) thermal/drivers/sun8i: Add support for A523 THS0/1 controllers
 - THS1 has four sensors; added the ths1_3 (NPU) calibration data
 - renamed the scale/offset constants to match the BSP naming
 - check caldata[1] instead of caldata[0] for the factory temperature
 - use SCALE_BELOW as the calibration divisor, as in the BSP
 - documented that the BSP CAL_COM(5000) is applied through ft_deviation
 - updated the commit description

5) arm64: dts: allwinner: sun55i: add thermal sensors
 - put nvmem-cell-names on a single line
 - dropped unused trip labels, kept the ones referenced by the cooling maps
 - renamed the "gpu-trips" container to "trips"
 - added the npu-thermal zone for the fourth THS1 sensor

Changes v5~v4:
1) dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
 - added empty line between what and context
 - clarified description
 - added missing period

2) thermal/drivers/sun8i: replace devm_reset_control_get to...
 - updated Reviewed-by tag

3) thermal/drivers/sun8i: get calibration data from two nvmem cells
 - removed dead IS_ERR(caldata) check
 - replaced NULL/IS_ERR check with IS_ERR_OR_NULL()

4) thermal/drivers/sun8i: Add support for A523 THS0/1 controllers
 - clarified description
 - added Reviewed-by tag

5) arm64: dts: allwinner: sun55i: add thermal sensors
 - fixed patch subject prefix
 - clarified description
 - sorted thermal-sensor nodes by base address
 - added empty lines between trip nodes (DT coding style)
