Subject: [PATCH v4 1/5] dt-bindings: thermal: sun8i: Add A523 THS0/1 controllers
Date: Mon,  4 May 2026 13:02:41 +0800	[thread overview]
Message-ID: <20260504050245.646078-2-iuncuim@gmail.com> (raw)
In-Reply-To: <20260504050245.646078-1-iuncuim@gmail.com>

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 mod clock property required.

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
