Exynos Usb Device4000 Hot |work| 100%

Excessive heat around the Exynos USB Device4000 typically stems from PHY power states, controller clocking, sustained high-bandwidth transfers, or driver/firmware omissions. A combination of targeted measurements, driver power-management fixes, clock gating, and board-level thermal improvements will mitigate the issue. Implement a validation plan with clear thermal and power criteria to ensure long-term stability.
