Add device-tree support for Cypress CYPD4226 Type-C controller and
enable for the Jetson AGX Orin board. This series is derived from the
series to enable USB host and device support for Jetson AGX Orin [0].
I have split this out from that series because it was getting quite
big.

Apologies, but we appear to be missing you on this series [0]. Please 
take a look at patches, 2, 3 and 4. If you are OK with the changes, I am 
not sure if it is easiest for Heikki or Greg to merge?

Thanks
Jon

Yup, me, the i2c-list and the dedicated maintainer for this driver:

$ scripts/get_maintainer.pl -f drivers/i2c/busses/i2c-nvidia-gpu.c
Ajay Gupta <ajayg@nvidia.com>
linux-i2c@vger.kernel.org
linux-kernel@vger.kernel.org

If Ajay Gupta is happy, you'll get my ack for free.
