From: Shaikh Mohammed Suhan <[email protected]> Add fixed supply regulators for the onboard USB hub (USB2744) used on Kria platforms.
The USB hub requires two always-on power rails: - vdd: 3.3V main supply - vdd2: auxiliary supply Model these rails as fixed regulators and reference them from the hub node to accurately describe the hardware.
