Subject: [PATCH v3 0/5] Add support for SW babble Control

Series add support for SW babble control logic found in 
new silicon versions of AM335x. Runtime differentiation of
silicon version is done by checking the BABBLE_CTL register.
For newer silicon the register default value read is 0x4 and
for older versions its 0x0.

Patch 1 -> Convert recover work to delayed work.
Patch 2 -> usb_phy_vbus_(off/_on) are NOPs for am335x PHY
	   so use usb_phy(_shutdown/_init) in musb_platform_reset()
Patch 3 -> Add return value for musb_platform_reset() in prepration
	   to support SW babble_ctrl
Patch 4 -> Add the sw_babble_control()
Patch 5 -> Enable sw babble control for newer silicon
	
v2 -> v3 : Modify musb_platform_reset() to return zero on success.

v1 -> v2 : Fixed the issue with Patch 5. In v1 it was not calling 
	   sw_babble_control().

George Cherian (5):
  usb: musb: core: Convert babble recover work to delayed work
  usb: musb: dsps: Call usb_phy(_shutdown/_init) during
    musb_platform_reset()
  usb: musb: core: Convert the musb_platform_reset to have a return
    value.
  usb: musb: dsps: Add the sw_babble_control()
  usb: musb: dsps: Enable sw babble control for newer silicon
