[PATCH v3 07/14] ARM: tegra: acer-a500: Reduce thermal throttling hysteresis to 0.2C

From: Dmitry Osipenko <digetx@gmail.com>
Date: 2021-03-02 13:22:44
Also in: lkml
Subsystem: the rest · Maintainer: Linus Torvalds

The 2C hysteresis is a bit too high, although CPU never gets hot on A500.
Nevertheless, let's reduce thermal throttling hysteresis to 0.2C, which is
a much more reasonable value.
