According to the "GPIO Expander Map / Table" section of the J722S EVM Schematic within the Evaluation Module Design Files package [0], the GPIO Pin P05 located on the GPIO Expander 1 (I2C0/0x23) has to be pulled down to select the Type-C interface. Since commit under Fixes claims to enable the Type-C interface, update the property within "p05-hog" from "output-high" to "output-low", thereby switching from the Type-A interface to the Type-C interface.

I have applied the following to branch ti-k3-dts-next on [1]. Thank you!
[1/1] arm64: dts: ti: k3-j722s-evm: Fix USB gpio-hog level for Type-C commit: 65ba2a6e77e9e5c843a591055789050e77b5c65e
All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent up the chain during the next merge window (or sooner if it is a relevant bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
