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.
