2010-03-19USB: musb: fix warnings in Blackfin regsMike Frysinger1-0/+9
The recent commit "usb: musb: Add context save and restore support" added some stubs for the Blackfin code so things would compile, but it also added a bunch of warnings due to missing return statements.

2010-03-19usb: musb: abstract out ULPI_BUSCONTROL register reads/writesMike Frysinger2-3/+21
The USB PHY on current Blackfin processors is a UTMI+ level 2 PHY. However, it has no ULPI support - so there are no registers at all. That means accesses to ULPI_BUSCONTROL have to be abstracted away like other MUSB registers. This fixes building for Blackfin parts again.

The recent commit "usb: musb: Fix for isochronous IN transfer" (f82a689fa) seems to have been against an older kernel version. It uses the old style naming of variables. Unfortunately, this breaks building for most MUSB users out there since "bDesiredMode" has been renamed to "desired_mode".

2010-03-02usb: musb: Fix cppi_channel_abort() function to handle Tx abort correctlySwaminathan S1-23/+10
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).

2010-03-02usb: musb: workaround toggle bug when doing bulk transfer after isocSwaminathan S1-0/+24
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.

2010-03-02usb: musb: workaround MUSB DMA_INTR sometimes reads zeroAnand Gadiyar1-3/+22
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.

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.
