2012-05-22USB: core: OTG Supplement Revision 2.0 updatesAvinash Kumar
OTG supplement revision 2.0 spec introduces Attach Detection Protocol (ADP) for detecting peripheral connection without applying power on VBUS. ADP is optional and is included in the OTG descriptor along with SRP and HNP. HNP polling is introduced for peripheral to notify its wish to become host. Host polls (GET_STATUS on DEVICE) peripheral for host_request and suspend the bus when peripheral returns host_request TRUE. The spec insists the polling frequency to be in 1-2 sec range and bus should be suspended with in 2 sec from host_request is set. a_alt_hnp_support feature is obsolete and a_hnp_support feature is limited to only legacy OTG B-device. The newly introduced bcdOTG field in the OTG descriptor is used for identifying the 2.0 compliant B-device.

The ABB link status interrupt is coming twice for LinkStatus = 18 and 13 ,one of them is to be ignored depending on the current ABB hardware version. However for the ignored one too, the ABB driver is sending a spurious USB_EVENT_NONE notification event ,which is thus shutting down the vbus needed for enumerating the device. Hence 5500 usb host is not enumerating any devices. Solution is not to post the event USB_EVENT_NONE for the ignored link status interrupt.

2012-05-22musb: host: Wait for TXPKTRDY to clear in hostThirupathi Chippakurthy
MUSB_TXCSR_TXPKTRDY will not get cleared if the data is not on the bus. So, need to wait for it to clear in the DMA completion callback.As per musb datasheet, generally mode 1 needs to be used for data length greater than or equal to max packet size. Bus reset happening due to scsi timeout,since in this case should not return continue for next transfers.

2012-05-22usb : musb : Do not register musb core PM opsrajaram
Currently musb core PM ops does save and restore of context The platform can enter CPU idle before the platform or runtime suspend is called.But musb core PM ops is not aware of CPU idle. and thus it saves and restores some junk context Since junk context is restored there is instability in usb functions. ux500 USB platform file handles the save and restore properly during cable connect and disconnent.So we don't require handling of context save and restore in musb core and hence not registering musb core PM ops.

The USB serial number which is exposed via sysfs is exposed at the /sys/serial_number which is improper location. Sysfs entries should be exposed from /sys/devices/platform/ using a kobject from the device struct. Added a new sysfs entry for delaying the enumeration. User space has to update the values in kernel space and then the enumeration will start.

2012-05-22u8500:USB:Handle multiple Link status fn callsSakethram Bommisetti
During boot time, multiple calls are made to Link status function by otg_set_host and otg_set_peripheral. This in turn calls clock and regulator enabling multiple times which creates problem with the reference count of regulators. Hence this blocks the CPU idle since the regulators are not released properly due to multiple acquire. So, Link status function calls are removed from otg_set_host and otg_set_peripheral which are not needed. The Link status call during boot shall be handled by the ab8500_usb_boot_detect function.
