usb: musb: cppi_dma: export cppi_interrupt()

2013-01-03T03:33:02Z

commit 8b416b0b25d5d8ddb3a91c1d20e1373582c50405 upstream. Now that DaVinci glue layer can be modular, we must export cppi_interrupt() that it may call... Signed-off-by: Sergei Shtylyov Signed-off-by: Felipe Balbi Signed-off-by: Ben Hutchings

usb: musb: cppi: fix build errors due to DBG and missing musb variable

2011-08-12T08:52:47Z

Replace DBG with dev_dbg and fix invalid access of musb->controller. With this patch cppi_dma builds successfully. Cc: Signed-off-by: Per Forlin Signed-off-by: Felipe Balbi

usb: musb: drop unneeded musb_debug trickery

2011-05-13T11:34:04Z

We have a generic way of enabling/disabling different debug messages on a driver called DYNAMIC_PRINTK. Anyone interested in enabling just part of the debug messages, please read the documentation under: Documentation/dynamic-debug-howto.txt for information on how to use that great infrastructure.

USB: musb: dereferencing an iomem pointer

2011-04-13T08:51:24Z

"tx_ram" points to io memory. We can't dereference it directly. Sparse complains about this: "drivers/usb/musb/cppi_dma.c:1205:25: warning: dereference of noderef expression" Signed-off-by: Dan Carpenter Signed-off-by: Felipe Balbi

USB: musb: using 0 instead of NULL

USB: musb: add missing unlock in cppi_interrupt()

We should unlock before returning here. Signed-off-by: Dan Carpenter Signed-off-by: Felipe Balbi

usb: musb: add names for IRQs in structure resource

2010-12-01T08:56:33Z

Soon resource data will get automatically populated from a set of autogenerated data from TI's hardware database for the OMAP platform. Such database, might not have resources at the expected order by the current drivers. While we could hack in some exceptions to that tool to generate resources in a specific order, it seems less fragile to use the resource name instead. That way, no matter what order the resources are generated, the driver still work. Modified the OMAP, Blackfin and Davinci architecture files to add the name of the IRQs in the resource structures and musb driver to use the platform_get_irq_byname() api to get the device and dma irq numbers instead of using the index.

usb: musb: gadget: fix dma length in txstate

2010-09-24T18:05:01Z

DMA length should not go beyond the availabe space of request buffer, so fix it. Also set max_len of cppi dma channel as max size of int type, so make musb dma handling happier.
