X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=fd55708d58c4b1155dc224d2abfb7dd99e12af7a;p=users%2Fjedix%2Flinux-maple.git

dt-bindings: thermal: Add support for Airoha EN7581 thermal sensor

Add support for Airoha EN7581 thermal sensor and monitor. This is a
simple sensor for the CPU or SoC Package that provide thermal sensor and
trip point for hot low and critical condition to fire interrupt and
react on the abnormal state.
