Subject: [PATCH 2/2] drivers: hwmon: lm75: add support for PCT2075
Date: Thu, 11 Jul 2019 14:45:04 +0200 [thread overview]
Message-ID: <20190711124504.7580-2-daniel@zonque.org> (raw)
In-Reply-To: <20190711124504.7580-1-daniel@zonque.org>
The NXP PCT2075 is largely compatible with other chips already supported
by the LM75 driver. It uses an 11-bit resolution and defaults to 100 ms
sampling period. The datasheet is here:
https://www.nxp.com/docs/en/data-sheet/PCT2075.pdf
