This patch set introduces a phy driver for samsung SoCs. It uses the existing transceiver infrastructure to provide phy control functions. Use of this driver can be extended for usb host phy as well.

How can you support usb host phy? I cannot choose to use which phy when call init or shutdown of phy at current phy framework.

Thanks.

Over the period of time all the phy
related code for most of the samsung SoCs can be integrated here. Removing the existing phy code from mach-s3c64xx. Same can be done for other SoCs when they start supporting this phy driver.
This driver is tested with smdk6410 and Exynos4210(with DT).
