Subject: [PATCH v3 1/6] dt-bindings: thermal: sun8i: Add A523 THS0/1
Add a binding for D1/T113s thermal sensor controller. Add dt-bindings
description of the thermal sensors in the A523 processor.
The controllers require activation of the additional frequency of the
associated gpadc controller, so a new clock property has been added.
The calibration data is split into two cells that are in different areas
of nvmem. Both controllers require access to both memory cell, so a new
property nvmem-cells has been added. To maintain backward compatibility,
the name of the old cell remains the same and the new nvmem-cell-names is
called calibration-second-part

Some processors (e.g. Allwinner A523) require GPADC clocking activation for
temperature sensors to work. So let's add support for enabling it.

The A523 processor has two temperature controllers, but they share a
common reset line. Make it shared with the shared variant of
devm_reset_control_get(), and also simplify the driver by switching to
devm_reset_control_get_shared_deasserted().

Subject: auto-split from bundle
The A523 processor has two temperature controllers, THS0 and THS1.
THS0 has only one temperature sensor, which is located in the DRAM.
THS1 does have 3 sensors:
ths1_0 - "big" cores
ths1_1 - "little" cores
ths1_2 - gpu
The datasheet mentions a fourth sensor in the NPU, but lacks any registers
for operation other than calibration registers. The vendor code reads the
value from ths1_2, but uses separate calibration data, so we get two
different values from real one.

Add the thermal sensor configuration and the thermal zones.
Trips temperature, polling-delay and sustainable-power parameters are
derived from the manufacturer's BSP.
