Subject: [PATCH] arm64: dts: rk3399-pinephone-pro: reduce thermal limits
Date: Wed,  7 Dec 2022 11:32:13 +0000	[thread overview]
Message-ID: <20221207113212.8216-1-kernel@undef.tools> (raw)

While this device uses the rk3399 it is also enclosed in a tight package
and cooled through the screen and back case. The default rk3399 thermal
limits can result in a burnt screen.

These lower limits have resulted in the existing burn not expanding and
will hopefully result in future devices not experiencing the issue.
