    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.
