* usb: dwc3: switch to GPL v2 onlyFelipe Balbi2013-07-291-27/+7Star
| | | | | | | | | | | | | | | | This is a Linux-only driver which makes use of GPL-only symbols. It makes no sense to maintain Dual BSD/GPL licensing for this driver. Considering that the amount of work to use this driver in any different operating system would likely be as large as developing the driver from scratch and considering that we depend on GPL-only symbols, we will switch over to a GPL v2-only license.

* usb: dwc3: debugfs: improve debugfs file creationFelipe Balbi2013-03-181-19/+22
| | | | | | | | | | | | | when commit 388e5c5 (usb: dwc3: remove dwc3 dependency on host AND gadget.) changed the way debugfs files are created, it failed to note that 'mode' is necessary in Dual Role mode only while 'testmode' and 'link_state' are valid in Dual Role and Peripheral-only builds. Fix this while also converting pre- processor conditional to C conditionals. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: dwc3: debugfs: mark our regset structure constFelipe Balbi2013-03-181-1/+1

| | | | | | | | | | | | | | | | | | | | DWC3 controller curretly depends on USB && USB_GADGET. Some hardware may like to use only host feature on dwc3, or only gadget feature. So, removing this dependency of USB_DWC3 on USB and USB_GADGET. Adding the mode of operaiton of DWC3 also here HOST/GADGET/DUAL_ROLE based on which features are enabled.

* usb: dwc3: debugfs: remove test mode interfaceSebastian Andrzej Siewior2011-09-091-94/+0Star
| | | | | | | | | | | | | | | | | | There are some issues around for enabling/disabling this mode and handling it. It does not work perfectly (yet). However we have a few gadgets tested successfuly so far. That means we are quite confident that we won't need this in near future. So I'm for removing it and bringing a working version back once there is a need for it. Thanks to Dan Carpenter who spotted the wrong memory handling here.

* usb: Introduce DesignWare USB3 DRD DriverFelipe Balbi2011-08-231-0/+534
The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.
