Subject: [PATCH v7 0/4] Add support for SW babble Control

Hi Felipe,

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 -> Handle Babble only if MUSB is in HOST mode
	   (This patch is available in linux-next but missing in your 
	    testing/next).
		
Patch 2 -> Convert recover work to delayed work.
Patch 3 -> Add return value for musb_platform_reset() in prepration
	   to support SW babble_ctrl
Patch 4 -> Add and Enable sw babble control for newer silicon

v6 -> v7 : Rebased for to balbi testing/next
v5 -> v6 : Squash patch 5 and 6 form v5 to avoid build warnings.

v4 -> v5 : Added a debug print before resetting MUSB.
	   changed a musb_readb to dsps_readb introduced in Patch#5 of v4.

v3 -> v4 : Fixes an issue in gagdet mode - BUS RESET should not
	   be handled as a BABBLE. Added a check for the same.(Patch #1)
	   Enable sw babble control properly (Patch #6)
	   	
v2 -> v3 : Modify musb_platform_reset() to return zero on success.

George Cherian (4):
  usb: musb: core: Handle Babble condition only in HOST mode
  usb: musb: core: Convert babble recover work to delayed work
  usb: musb: core: Convert the musb_platform_reset to have a return
    value.
  usb: musb: dsps: Add the sw_babble_control() and Enable for newer
    silicon
