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

[George Cherian <george.cherian@ti.com>]

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
