2014-02-06usb: mv_udc: Rename to ci_udcMarek Vasut
The mv_udc is not marvell-specific anymore. The mv_udc is used to drive generic ChipIdea CI13xxx series OTG cores, so rename the driver to ci_udc instead. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Eric Nelson <eric.nelson@boundarydevices.com> Cc: Stefano Babic <sbabic@denx.de>
2013-10-20usb: gadget: mv_udc: split mv_udc.h fileTroy Kisky
Move defines only needed by mv_udc.c to a file in the same directory. This allows usbtty to compile for mv_udc, but it still doesn't link. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: optimize ep_enableTroy Kisky
Only get head if not ep0. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: optimize bounceTroy Kisky
Only perform one copy, either in the bounce routine for IN transfers, or the debounce rtn for OUT transfer. On out transfers, only copy the number of bytes received from the bounce buffer Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: fix full speed connectionsTroy Kisky
Set maximum packet length in queue header to wMaxPacketSize of endpoint. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: don't check CONFIG_USB_MAX_CONTROLLER_COUNTTroy Kisky
i.mx6 has 1 otg controller, and 3 host ports. So, CONFIG_USB_MAX_CONTROLLER_COUNT can be greater than 1 even though only 1 device mode controller is supported. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: add enum usb_init_type parameter to usb_lowlevel_initTroy Kisky
This parameter will later be used to verify OTG ports. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: clear desc upon ep_disableTroy Kisky
desc is set at ep_enable, so for symmetry, clear it at ep_disable. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: zero transfer descriptor memory on probeTroy Kisky
Since we flush the TD, we may as well set it to a known value. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>
2013-10-20usb: gadget: mv_udc: flush item before headTroy Kisky
Make sure the transfer descriptor is flushed before the queue is updated so that the controller will not see old information. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

2013-07-29usb: mv_udc: Add bounce bufferMarek Vasut
The requests sent to the controller are not properly cache aligned most of the time, thus implement a simple bounce buffer to avoid problem with cache.

2013-07-29usb: mv_udc: Add proper cache managementMarek Vasut
Implement functions to flush/invalidate dcache over QH and qTDs and make use of them where appropriate. Also use them to replace the old incorrect cache management attempt. This is the first step towards making this driver work with data cache enabled.

2013-07-29usb: mv_udc: Implement better qTD item accessorMarek Vasut
The code for retrieving qTD item for particular endpoint is hard to understand, moreover it's duplicated all over the driver. Move the code into single nice and documented function.

2013-07-29usb: mv_udc: Improve allocation of qTD itemsMarek Vasut
Allocate the qTD items all at once instead of allocating them separately. Moreover, make sure each qTD is properly aligned to 32-bytes boundary and that cache can be safely flushed over each qTD touple.

2013-07-29usb: mv_udc: Add cacheline length checkMarek Vasut
Check the length of system cacheline at compile-time and fail if the system uses too long cachelines.

2013-07-29usb: mv_udc: Properly align the endpoint QH and qTD listMarek Vasut
The endpoint QH list has to be aligned to 10-bit boundary. We also have to make sure the list is aligned on a cacheline boundary. Make sure it is. Furthermore, check if the memory allocation for the QH list didn't fail. Moveover, improve the comment about the QH list structure. Finally, the qTD item list has to be aligned only to 5-bit boundary, not 10-bit as it is now, fix this as well.

2013-07-29usb: mv_udc: Clean up the initial variable checkMarek Vasut
Clean up the code that checks the validity of a USB gadget driver in usb_gadget_register_driver(). Moreover, limit the speed of the driver to either FULL or HIGH, this is more precise and once we have xHCI support, also more correct.

2013-07-29usb: mv_udc: Make use of struct ehci_ctrlMarek Vasut
The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.

2013-07-29usb: mv_udc: Clean up the EP initializationMarek Vasut
Move the constant values that are programmed into mv_ep.ep into separate static const structure so they can be memcpy()'d when the initialization happens. Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS, so fix this bug as well.

2013-07-29usb: mv_udc: Move endpoint array into driver dataMarek Vasut
The endpoints are operated on a per-controller basis, move the endpoint array into controller's private data. Also shuffle the struct mv_ep structure definition just above the definition of the struct mv_drv so they're well grouped together.
