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

Based on 7.1-rc1.

Changes v4~v3:
1) dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
 - gpadc replaced to mod clock

x) thermal/drivers/sun8i: add gpadc clock
 - removed

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

3) thermal/drivers/sun8i: get calibration data from two nvmem cells
 - no functional changes

4) thermal/drivers/sun8i: Add support for A523 THS0/1 controllers
 - gpadc replaced to mod clock

5) arm64: dts: allwinner: A523: Add thermal sensors and zones
 - gpadc replaced to mod clock

v3 https://lore.kernel.org/linux-sunxi/20251025043129.160454-1-iuncuim@gmail.com
Changes v3~v2:
x) dt-bindings: nvmem: SID: Add binding for A523 SID controller
 - previously accepted, therefore removed from this version

1) dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
 - added changes as requested by Rob

2) thermal/drivers/sun8i: add gpadc clock
 - removed undescribed changes spaces to tabs

3) thermal/drivers/sun8i: replace devm_reset_control_get to
 - changed the commit description to the version suggested by wens
 - added reviewed-by tag

4) thermal/drivers/sun8i: get calibration data from two nvmem cells
 - added spaces in the description block before "*"

5) thermal/drivers/sun8i: Add support for A523 THS0/1 controllers
 - added alignment of functions in compliance with open parenthesis

x) arm64: dts: allwinner: A523: Add SID controller node
 - previously accepted, therefore removed from this version

6) arm64: dts: allwinner: A523: Add thermal sensors and zones
 - no functional changes

Changes v2~v1:
1) dt-bindings: nvmem: SID: Add binding for A523 SID controller
 - added new patch

2) dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
 - changed clock order
 - added additional nvmem cell with calibration data
 - added requirements for new controllers
 - added description

3) thermal/drivers/sun8i: add gpadc clock
 - removed unnecessary call to clk_prepare_enable() since
 devm_clk_get_enabled()includes this

4) thermal/drivers/sun8i: replace devm_reset_control_get to
 - original function replaced with devm_reset_control_get_shared_deasserted()
 - removed some of the repetitive code executed by 
 devm_reset_control_get_shared_deasserted()

5) thermal/drivers/sun8i: get calibration data from two nvmem cells
 - added possibility to get calibration data from two independent cells

6) thermal/drivers/sun8i: Add support for A523 THS0/1 controllers
 - removed magic digits
 - changed description of calibration data procedure for A523
 - changed numbers of array elements with calibration data

7) arm64: dts: allwinner: A523: Add SID controller node
 - fix typo (sun50i->sun55i)

8) arm64: dts: allwinner: A523: Add thermal sensors and zones
 - cell with calibration data divided into two
 - added passive trips for gpu
 - added information that information obtained from BSP
