Kernel driver i2c-nvidia-gpu
Datasheet: not publicly available.
Authors:
Ajay Gupta <ajayg@nvidia.com>
Description
-----------
i2c-nvidia-gpu is a driver for I2C controller included in NVIDIA Turing
and later GPUs and it is used to communicate with Type-C controller on GPUs.
If your 'lspci -v' listing shows something like the following,
01:00.3 Serial bus controller [0c80]: NVIDIA Corporation Device 1ad9 (rev a1)
then this driver should support the I2C controller of your GPU.
