[PATCH V10 0/6] Add device-tree support for Cypress CYPD4226

[PATCH V10 0/6] Add device-tree support for Cypress CYPD4226

[Jon Hunter]

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.

[PATCH V10 2/6] i2c: nvidia-gpu: Add ACPI property to align with device-tree

[Jon Hunter]

From: Wayne Chang <waynec@nvidia.com>

Device-tree uses the 'firmware-name' string property to pass a name of
the firmware build to the Cypress CCGx driver. Add a new ACPI string
property to the NVIDIA GPU I2C driver to align with device-tree so that
we can migrate to using a common property name for both ACPI and
device-tree.

[PATCH V10 3/6] usb: typec: ucsi_ccg: Add OF support

[Jon Hunter]

From: Wayne Chang <waynec@nvidia.com>

Add device-tree support for the Cypress CCG UCSI driver. The device-tree
binding for the Cypress CCG device uses the standard device-tree
'firmware-name' string property to indicate the firmware build that is
used.

The NVIDIA GPU I2C driver has been updated to use an ACPI string
property that is also named 'firmware-build' and given that this was the
only users of the 'ccgx,firmware-build' property, we can now remove
support for this legacy property.

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?

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.
