Subject: [PATCH v3 07/14] ARM: tegra: acer-a500: Reduce thermal throttling hysteresis to 0.2C
Date: Tue, 2 Mar 2021 15:09:56 +0300 [thread overview]
Message-ID: <20210302121003.15058-8-digetx@gmail.com> (raw)
In-Reply-To: <20210302121003.15058-1-digetx@gmail.com>
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.
