[PATCH RFC 0/4] Add Exynos5 USB 3.0 phy driver based on generic PHY framework

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Adding a phy driver for USB 3.0 PHY controller present on Exynos5
series of SoCs alongwith DWC3 controller for USB 3.0 operations.

This driver is inline with Kamil's USB 2.0 phy driver. [1]
Few functions used to translate ref clock rate are common to
Kamil's changes. So we can figure out how to re-use them across
these drivers.

Theses patches are based on usb-next branch and tested with
Kishon's patches for adapting DWC3 to generic phy framework, [2]
on smdk5250 as well as smdk5420 board.
