Subject: [PATCH v2 2/8] dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers

From: Mikhail Kalashnikov <iuncuim@...il.com>

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
