Hi Kishon,
Recently, I posted 'simple-phy' driver.
It is a part of patchset for HDMI enabling on Exynos4 using Device Tree.

http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg23655.html

The simple-phy was dedicated for single register PHYs like HDMI or DP.
Using such a generic phy may help to avoid code duplication.

Regards,
Tomasz Stanislawski
