      usb: otg: notifier: switch to atomic notifier · cccad6d4
      Felipe Balbi authored 
      most of our notifications, will be called from IRQ
context, so an atomic notifier suits the job better.

      usb: musb: OMAP4430: Fix usb device detection if connected during boot · 002eda13
      Hema HK authored 
      OMAP4430 is embedded with UTMI PHY. This PHY does not support the
OTG features like ID pin detection and VBUS detection. This function
is exported to an external companion chip TWL6030. Software must retrieve
the OTG HNP and SRP status from the TWL6030 and configure the bits inside
the control module that drive the related USBOTGHS UTMI interface signals.
It must also read back the UTMI signals needed to configure the TWL6030
OTG module.

Can find more details in the TRM[1].
[1]:http://focus.ti.com/pdfs/wtbu/OMAP4430_ES2.0_Public_TRM_vJ.pdf

In OMAP4430 musb driver VBUS and ID notifications are received from the
transceiver driver. If the cable/device is connected during boot,
notifications from transceiver driver will be missed till musb driver
is loaded.
Patch to configure the transceiver in the platform_enable/disable
functions and enable the vbus in the gadget driver based on the
last_event of the otg_transceiver.

      usb: otg: TWL6030 Save the last event in otg_transceiver · 647b2d9c
      Hema HK authored 
      Save the last event in the otg_transceiver so that it can used in the
musb driver and gadget driver to configure the musb and enable the
vbus for host mode and OTG mode, if the device is connected during boot.

      Introduce the twl6030_phy_suspend function and assign to otg.set_suspend
function pointer.
This function is used by the musb-omap2430 platform driver
during suspend/resume.

      usb: otg: OMAP4430: Introducing suspend function for power management · ee896e34
      Hema HK authored 
      Introduced the suspend/resume function for the OMAP4430 internal PHY.
This will be used by the twl6030-usb transceiver driver.
Moved the clock enable/disable function calls and power on/off of the PHY
code from power on/off functions to suspend/resume function.

Pass the suspend function through board data for OMAP4430sdp and OMAP4panda.
This will be used by the twl6030-usb transceiver driver.

      To get the ID status there was an I2C read transfer. Removed this I2C

      usb: otg: enable regulator only on cable/device connect · 6dc2503b
      Hema HK authored 
      Remove the regulator enable while driver loading and enable it only when
the cable/device is connected and disable it when disconnected.

Remove the configuration of config_state and config_trans register
configuration as these registers are programmed when regulator
enable/disable is called.

      usb: musb: Using runtime pm APIs for musb. · 207b0e1f
      Hema HK authored 
      Calling runtime pm APIs pm_runtime_put_sync() and pm_runtime_get_sync()
for enabling/disabling the clocks, sysconfig settings.

Enable clock, configure no-idle/standby when active and configure force idle/standby
and disable clock when idled. This is taken care by the runtime framework when
driver calls the pm_runtime_get_sync and pm_runtime_put_sync APIs.
Need to configure MUSB into force standby and force idle mode when usb not used

      usb: musb: gadget: do not poke with gadget's list_head · ad1adb89
      Felipe Balbi authored 
      struct usb_request's list_head is supposed to be
used only by gadget drivers, but musb is abusing
that. Give struct musb_request its own list_head
and prevent musb from poking into other driver's
business.

      usb: musb: gadget: beautify usb_gadget_probe_driver()/usb_gadget_unregister_driver · 63eed2b5
      Felipe Balbi authored 
      Just a few cosmetic fixes to usb_gadget_probe_driver()
and usb_gadget_unregister_driver().

Decreased a few indentation levels with goto statements.

While at that, also add the missing call to musb_stop().
If we don't have OTG, there's no point of leaving
MUSB prepared for operation if a gadget driver fails
to probe. The same is valid for usb_gadget_unregister_driver(),
since we are removing the gadget driver and we don't have
OTG, we can completely unconfigure MUSB.
