Subject: [PATCH v1 6/7] hwmon: (it87) Add new chipset IT87952E
Date: Thu, 26 Jan 2023 15:02:22 +1100 [thread overview]
Message-ID: <20230126040223.986189-7-frank@crawford.emu.id.au> (raw)
In-Reply-To: <20230126040223.986189-1-frank@crawford.emu.id.au>
Add IT87952E, a new chip ID (DEV ID 0x8695), which appears to be an
updated version of the IT8792E and takes the same configuration.
The model name comes from the model name printed on the chip.
There is no datasheet publicly available.
