v2 looks good, thanks. :) As a side note, we are working on the USB PHYs
driver using the generic PHY framework (actually Kamil is working on that).
Thus it is likely the original driver will get replaced in near future by
something else. Not sure when that happens exactly but I suspect it is
not worth to invest in the Samsung USB PHY drivers at drivers/usb/phy/
too much and introduce changes, especially in *.dts, that won't be for
long time in use. Perhaps Kamil can provide more details on which devices
are initially going to be covered by the new driver.
