[PATCH v2 1/3] dt-bindings: thermal: amlogic: add S4

[christian . koever-draxl]

From: Christian Stefan Kövér-Draxl <ckoever@xxxxxxxxxx>

The S4 temperature sensors are the G12A design, but like on T7 their
calibration value is only available through the secure monitor: the
ao-secure register used on G12A holds unrelated data on S4. Add a
compatible for them. As on T7 the sensor index is the argument of the
secure monitor phandle, so one compatible serves the CPU and the DDR
sensor. Each sensor has a bus clock gating register access (ts_pll /
ts_ddr in the S4 peripheral clock controller) besides the functional
clock, so it takes both, named.
