Subject[PATCH 0/5 v12] mfd: omap: usb: Runtime PM support for EHCI and OHCI drivers
From: Keshava Munegowda <>

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.

- Adding mux-information to Hwmods.
- Aggressive Clock Management around USB bus suspend/resume.
- Remote Wakeup support implementation using IO-ring Wakeup
on EHCI/OHCI pads via PRCM IRQ chain handler.

In version 12:
- The ehci, ohci and usb_host_hs hwmods combined as a single hwmod
- for omap3
the usbhost_ick and and usbtll_ick clocks are changed as interface
clocks. The usbtll_fck, usbhost_48m_fck clocks are changed as main
clocks and the 120mhz functional clock is changed to optional clock
- the usbhs mfd driver enable/disable this optional clock in
runtime_resume and runtime_suspend callbacks of pm_runtime_get_sync
and pm_runtime_put_sync APIs.
