dt-bindings: thermal: r9a09g047-tsu: document RZ/T2H and RZ/N2H
The Renesas RZ/T2H (R9A09G077) and RZ/N2H (R9A09G087) SoCs include a
Temperature Sensor Unit (TSU). The device provides real-time temperature
measurements for thermal management, utilizing a single dedicated
channel for temperature sensing.
Compared to the previously supported RZ/G3E, the RZ/T2H and RZ/N2H SoCs
do not have a reset for the TSU peripheral, and the OTP data is exposed
via ARM SMC, as opposed to a system register.
