Subject: [PATCH 3/5] usb: phy: samsung: remove old USB 2.0 PHY driver

I would say it co-incidence that both of us sent the patch-series for 
similar cleanup at the same time. ;)

There's one thing that I would want to comment here, since we don't have any 
new usb-phy driver for S3C64XX,
so we can't simply remove this entire driver.
I have posted my patch-series [1], which does cleanup while keeping the 
support for S3C64XX.

Please let me know what you think of that series.
