Subject: [PATCH v1 3/9] ARM: tegra: p880: Lower CPU thermal limit
Date: Mon, 6 Apr 2026 11:33:58 +0300 [thread overview]
Message-ID: <20260406083404.31359-4-clamor95@gmail.com> (raw)
In-Reply-To: <20260406083404.31359-1-clamor95@gmail.com>
From: Ion Agorria <ion@agorria.com>
Lower the CPU thermal limit for the LG P880, since its chassis has less
thermal dissipation capability than the P895.
