Subject: [PATCH v3 3/4] thermal: mediatek: add support for MT8365 SoC
Date: Thu, 1 Sep 2022 15:39:49 +0200 [thread overview]
Message-ID: <20220901133950.115122-4-aouledameur@baylibre.com> (raw)
In-Reply-To: <20220901133950.115122-1-aouledameur@baylibre.com>
From: Fabien Parent <fparent@baylibre.com>
MT8365 is similar to the other SoCs supported by the driver. It has only
one bank and 3 actual sensors that can be multiplexed. There is another
one sensor that does not have usable data.
