Cover letter [U-Boot] [PATCH 0/7] USB: XHCI: Add xHCI host controller stack driver

Vivek

Quoted 36 lines · Vivek Gautam

This change adds necessary xHCI host controller stack layer. This stack will eventually interact with SoC specific USB 3.0 controller drivers to enable USB 3.0 support on different boards.

Based on 'master' branch of u-boot-usb tree.

The series also includes patches to support xHCI on exynos5250, including required driver, device tree changes and a temporary config change to test things finally on smdk5250.

Vivek Gautam (7):
arm: exynos5250: Define CONFIG_SYS_CACHELINE_SIZE
USB: xHCI: Add stack support for xHCI
USB: XHCI: Add xHCI host controller support for Exynos5
arm: exynos: Add methods to control power to USB 3.0 PHY
exynos5: dts: Add COMPAT string data for USB 3.0 PHY and XHCI
exynos5: dts: Add device node for XHCI
temp: ARM: EXYNOS5: Enable xHCI support for Exynos5

I have done similar work for the DWC and xHCI back port. We seem to have two different implementations.

See my V3 patch series. If you want the initial patch sets or v2 let me know.
