Subject: [PATCH v7 0/4] Add support for SW babble Control
Date: Wed, 16 Jul 2014 18:22:08 +0530	[thread overview]
Message-ID: <1405515132-17618-1-git-send-email-george.cherian@ti.com> (raw)

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 the musb_platform_reset to have a return
    value.
  usb: musb: dsps: Add the sw_babble_control() and Enable for newer
    silicon
