Subject: [PATCH v2 0/5] Add support for SW babble Control
Date: Thu, 8 May 2014 15:05:38 +0530 [thread overview]
Message-ID: <1399541743-14158-1-git-send-email-george.cherian@ti.com> (raw)
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
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
