Subject: [PATCH 3/3] arm64: dts: ti: k3-j7200-thermal: Add cooling maps and cpu_alert trip at 75C
Date: Wed, 9 Aug 2023 23:09:05 +0530	[thread overview]
Message-ID: <20230809173905.1844132-4-a-nandan@ti.com> (raw)
In-Reply-To: <20230809173905.1844132-1-a-nandan@ti.com>

From: Keerthy <j-keerthy@ti.com>

Add cooling maps and mpu_alert trip at 75C

Note: mpu_alert trip value should adjusted based on the system load and
performance needs.
