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
