[ Upstream commit 33e24f0738b922b6f5f4118dbdc26cac8400d7b9 ]
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.
