From: Keshava Munegowda <Keshava_mgowda@ti.com>
The Hwmod structures and Runtime PM features are implemented
For EHCI and OHCI drivers of OMAP3 and OMAP4.
The global suspend/resume of EHCI and OHCI
is validated on OMAP3430 sdp board with these patches.
these patches are rebased to kevin's pm branch and
usbhs latest mainline kernel patches
TODO:
- Aggressive clock cutting in usb bus suspends
- Remote Wakeup implementation using irq-chaing

Following 4 hwmod strcuture are added:
UHH hwmod of usbhs with uhh base address and functional clock,
EHCI hwmod with irq and base address,
OHCI hwmod with irq and base address,
TLL hwmod of usbhs with the TLL base address and irq.

Following 4 hwmod strcuture are added:
UHH hwmod of usbhs with uhh base address and functional clock,
EHCI hwmod with irq and base address,
OHCI hwmod with irq and base address,
TLL hwmod of usbhs with the TLL base address and irq.

device name usbhs clocks are changed from
usbhs-omap.0 to usbhs_omap; this is because
in the hwmod registration the device name is set
as usbhs_omap; The redudant clock nodes are removed.

From: Keshava Munegowda <Keshava_mgowda@ti.com>
The usbhs core driver does not enable/disable the interface and
functional clocks; These clocks are handled by hwmod and runtime pm,
hence insted of the clock enable/disable, the runtime pm APIS are
used. however,the port clocks are handled by the usbhs core.

From: Keshava Munegowda @ 2011-08-17 11:43 UTC (permalink / raw)

From: Keshava Munegowda <Keshava_mgowda@ti.com>
The usbhs core driver does not enable/disable the interface and
functional clocks; These clocks are handled by hwmod and runtime pm,
hence insted of the clock enable/disable, the runtime pm APIS are
used. however,the port clocks are handled by the usbhs core.

Yes, I will add this for omap3 , for omap4 this flag is causing
enumeration issue.
for now , I will not add this for 4430.
