From 049d141161903e656d9475950bb976240802c01c Mon Sep 17 00:00:00 2001 From: Dmitry Rokosov Date: Thu, 28 Mar 2024 22:26:36 +0300 Subject: [PATCH] arm64: dts: amlogic: a1: introduce cpu temperature sensor The A1 SoC family has only one thermal sensor for CPU temperature measurement. It is required to set the TS clock rate to 500kHz to make it workable.
