Subject: i2c: nvidia-gpu: Add ACPI property to align with device-tree
X-Git-Tag: v6.6.17~5457^2~74
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f510b0a3565b9231e828e23a7e0f9790b97edf96;p=platform%2Fkernel%2Flinux-rpi.git

i2c: nvidia-gpu: Add ACPI property to align with device-tree

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.
