Driver //free\\ — Exynos 7885 Usb
The Exynos 7885 is a mid-range SoC from Samsung (ARM-based, big.LITTLE: dual Cortex‑A73 + hexa Cortex‑A53, Mali‑G71 GPU). USB controller functionality on devices using this SoC is implemented by a combination of on‑chip hardware blocks and the operating system USB stack. A complete USB driver implementation must manage the SoC’s USB controller (PHY + controller IP), platform integration (clocks, regulators, pinmux), PHY initialization and calibration, power management, role switching (host/device/OTG), endpoints, DMA, and integration with higher‑level USB frameworks (e.g., Linux’s USB Gadget, USB Core, and xHCI/UDC layers).
