Date: Thu, 22 May 2014 11:59:35 +0530 From: George Cherian <george.cherian@...com> To: <linux-kernel@...r.kernel.org>, <linux-usb@...r.kernel.org>, <linux-omap@...r.kernel.org> CC: <gregkh@...uxfoundation.org>, <balbi@...com>, <zonque@...il.com>, <b-liu@...com>, George Cherian <george.cherian@...com> Subject: [PATCH v5 0/6] Add support for SW babble Control 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 Patch 2 -> Convert recover work to delayed work. Patch 3 -> usb_phy_vbus_(off/_on) are NOPs for am335x PHY so use usb_phy(_shutdown/_init) in musb_platform_reset() Patch 4 -> Add return value for musb_platform_reset() in prepration to support SW babble_ctrl Patch 5 -> Add the sw_babble_control() Patch 6 -> Enable sw babble control for newer silicon 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 (6): usb: musb: core: Handle Babble condition only in HOST mode 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 drivers/usb/musb/musb_core.c | 27 ++++++++------ drivers/usb/musb/musb_core.h | 12 +++--- drivers/usb/musb/musb_dsps.c | 87 ++++++++++++++++++++++++++++++++++++++++++-- drivers/usb/musb/musb_regs.h | 7 ++++ 4 files changed, 113 insertions(+), 20 deletions(-) -- 1.8.3.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
