What about xHCI? I have no idea about OHCI, but why won't you be able to have OHCI and ULPI PHY? > > > > +void ulpi_iface_ctrl_flags > > > + (struct usb_ehci *ehci, struct ulpi_regs *ulpi, int access_mode, > > > > u32 > > > > > flags) +{ > > > + switch (access_mode) { > > > + case WRITE: > > > + ulpi_write(ehci, (u32)&ulpi->iface_ctrl_write, flags); > > > + break; > > > + case SET: > > > + ulpi_write(ehci, (u32)&ulpi->iface_ctrl_set, flags); > > > + break; > > > + case CLEAR: > > > + ulpi_write(ehci, (u32)&ulpi->iface_ctrl_clear, flags); > > > + break; > > > + } > > > + > > > +} > > > > Is this crap from linux or something? > > No, Linux has offset-based access to ULPI registers, some structure > otg_transceiver, where the driver sets the bits which it wants to be set in > ULPI registers (if I understand it well) and family of functions, which set > bits according to informations in otg_transceiver. Ok, you have writel() functions, why do you need this switch stuff ? _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
