By the time I created this binding the binding for the kernel was not mainline, so I decided to use barebox,x to not end up with an incompatible binding. As the binding made it mainline now we can drop the "barebox," now. > > Second, how specify flags for USB ports, for example MXC_EHCI_INTERNAL_PHY? > In DT case we can not do it and as result desired port not functional... Could it be that this flag should simply be dropped? According to the Block diagram (Freescale i.MX53 ref manual v2.1, page 4700) the otg port is hardwired to the internal utmi phy, so having this configurable makes no sense.
