[RESEND][PATCH 0/5] arm: omap: usb: Runtime PM support for EHCI and OHCI drivers

[Keshava Munegowda]

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.

Keshava Munegowda (5):
  arm: omap: usb: ehci and ohci hwmod structures for omap3 and omap4
  arm: omap: usb: register hwmods of usbhs
  arm: omap: usb: device name change for the clk names of usbhs
  arm: omap: usb: Runtime PM support
  arm: omap: usb: global Suspend and resume support of ehci and ohci

[RESEND][PATCH 0/5] arm: omap: usb: Runtime PM support for EHCI and OHCI drivers

[Keshava Munegowda]

Following 2 hwmod strcuture are added:
UHH hwmod of usbhs with uhh base address and
EHCI , OHCI irq and base addresses.
TLL hwmod of usbhs with the TLL base address and irq.

[RESEND][PATCH 3/5] arm: omap: usb: device name change for the clk names of usbhs

[Keshava Munegowda]

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

[RESEND][PATCH 3/5] arm: omap: usb: device name change for the clk names of usbhs

[Keshava Munegowda]

From: Keshava Munegowda <Keshava_mgowda@ti.com>

The usbhs core driver does not enable/disable the intefrace and
fucntional 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 and tll clocks are handled
by the usbhs core.

[RESEND][PATCH 3/5] arm: omap: usb: device name change for the clk names of usbhs

[Keshava Munegowda]

From: Keshava Munegowda <Keshava_mgowda-l0cyMroinI0@public.gmane.org>

The global suspend and resume functions for usbhs core driver
are implemented.These routine are called when the global suspend
and resume occurs. Before calling these functions, the
bus suspend and resume of ehci and ohci drivers are called
from runtime pm.

[RESEND][PATCH 3/5] arm: omap: usb: device name change for the clk names of usbhs

[Keshava Munegowda]

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
