X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f41eaaa5f2c9fb4fc816e45e2061d80c0b927d39;p=thirdparty%2Flinux.git

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.
