From: Benoit Cousson <b-cousson@xxxxxx>
Following 4 hwmod structures are added
1. usb_host_hs hwmod of usbhs with uhh base address and functional clock,
2. usb_ehci_hs hwmod with irq and base address,
3. usb_ohci_hs hwmod with irq and base address,
- The ehci and ohci hwmods does not require functional clock
because usb_host_hs has functional clock which is sufficient
to access ehci and ohci address space.
- The usb_ehci_hs and usb_ohci_hs should be two separate hwmods
which should not be combined. This is needed because ehci and
ohci will have separate dedicated ports & in omap4 there is a
clock per port.We should be able to configure the IO-Wakeup
capability of pins specific to EHCI & OHCI separately and depending
on the I/O wakeup event the only port clocks corresponding
to the wakeup source will be enabled internally by the usb host driver.
4. usb_tll_hs hwmod of usbhs with the TLL base address and irq.
Signed-off-by: Benoit Cousson <b-cousson@xxxxxx>
- The initial version had only two hwmods,usb_host_hs and usb_tll_hs.
These two hwmods are reorganized as above four hwmods, because there
will be dedicated ports for ehci and ohci; and each port will have I/O
mux, which will be initialized per hwmod in future.
- migrated these hwmod structures to Kevin's pm branch:
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git .
