OMAP3 has three HS USB ports so it can have three different regulator for each PHY connected to each port. Currently these regulators are assumed to be optional and driver doesn't fail but continue with the initialization if it doesn't get any regulators. Regulator supply names has to be mapped in board files as 'hsusbN' where 'N' is port number and can be {0, 1 ,2}. Signed-off-by:Ajay Kumar Gupta <ajay.gupta@ti.com> Signed-off-by:

Some of the board might use external Vbus power supply on musb interface which would require to program ULPI_BUSCONTROL register. Adding 'extvbus' flag which can be set from such boards which will be checked at musb driver files before programming ULPI_BUSCONTROL. Signed-off-by:

This patch fixes the Tx abort/teardown logic. We now wait for the teardown completion interrupt and acknowledge the same by setting the tx_complete register to 0. This change is needed to ensure that abort processing works on DM365 platform. Without this change after completion of abort processing the system is overwhelmed with continuous stream of abort interrupts. This change has been tested on all CPPI3.x platforms (DM644x, DM646x, DM35x, DM36x). Signed-off-by:

This patch implements the work around for a Mentor controller related bug where it's observed a BULK Tx toggle error on the bus when a BULK IO gets scheduled on an endpoint that was earlier used for handling ISOC transaction and needed to start on 1 toggle. When such a situation arises even if the TXCSR toggle bits are programmed correctly by the musb driver the data gets transmitted with 0 toggle which leads to toggle error on the bus and the BULK transaction fails. In case of MSC write, the device gets reset by the Host. This Mentor bug is observed on almost all Mentor versions (1.3, 1.5, 1.8). Confirmed on DM644x, DM355, DM365, OMAPL13x platforms.

MUSB DMA_INTR register may sometimes read zero when infact there was a pending interrupt. Workaround this by reading the DMA_COUNT values for all enabled channels when this condition occurs. Flag these channels as the ones needing to be serviced. Additionally, the absence of a debug print meant we would never catch a spurious DMA interrupt in MUSB. So this patch adds a debug print in the IRQ handler. Signed-off-by:

We have observed MSC data read corruption when USB LAN device is also connected and it's interface is up. Silicon team has confirmed an errata where in all the active transfers should use FIFO space either in first 8K or next 8K. So far we have observed the issue in above use case scenario. As a workaround to it, adding a new FIFO config (5) fitting well within first 8K which can be used for such use cases. Signed-off-by:

Return values are being initialised to zero only to be unconditionally assigned to a few instructions later. This may give the impression that zero is returned on success, which is not the case. Note also that ftdi_NDI_device_setup never reports errors. Signed-off-by:

Currently a non-root-hub USB device's wakeup settings are initialized when the device is set to a configured state using device_init_wakeup(), but this is not correct as wakeup is split into "capable" (can_wakeup) and "enabled" (should_wakeup). The settings should be initialized instead in the device initialization (usb_new_device) with the "capable" setting disabled and the "enabled" setting enabled. The "capable" setting should be set based on the device being configured or unconfigured, and "enabled" setting set based on the sysfs power/wakeup control. This patch retains the sysfs power/wakeup setting of a non-root-hub USB device over a USB device re-configuration, which can happen (for example) after a suspend/resume cycle. Signed-off-by:

The pbLua console port is known to not be a modem, so it is unnecessary to be told this when it is plugged in. Add NOT_A_MODEM quirk to tell the driver that we know this already and hence not to warn us, and mark the pbLua console port. Signed-off-by:

The pbLua firmware (http://pblua.com/) for the Lego Mindstorms NXT provides a CDC ACM port for it's serial console. This used to be detected automatically, but this support has been dropped, probably for sensible reasons. Explicitly add support for this device by adding an item to the device ID table.

Due to a simple oversight when bus zero was added, the text API fails to deliver the bus number in 'E' messages (which are equivalent of 'C' messages, only for error case). This makes it harder, for instance, use a search-and-highlight in a text editor. So fix it. Also, Alan Stern requested adding timestamps to 'E' messages. This is purely cosmetic, but makes it easier to read the trace. This is done for both text and binary APIs. Signed-off-by:

Normally, the musb uses ep1 as the bidirectional bulk endpoint. This won't work on the Blackfin musb as all endpoints (except ep0) are unidirectional. Further, ep1-ep4 have a small 128 byte FIFO which makes them undesirable for bulk endpoints (which need more like a 512 byte FIFO). This leaves us with ep5-ep7 which have 1024 byte FIFOs and can be configured as either in/out and bulk/interrupt/iso on the fly. Signed-off-by:
