2015-08-06usb: musb: gadget: add musb_match_ep() functionRobert Baldyga2-23/+34
Add 'match_ep' callback to utilize chip-specific knowledge in endpoint matching process. Function does the same that was done by chip-specific code inside of epautoconf. Now this code can be removed from there to separate generic code from platform specific logic. Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

2015-08-06usb: gadget: move find_ep() from epautoconf to udc-coreRobert Baldyga2-21/+30
Move find_ep() to udc-core and rename it to gadget_find_ep_by_name(). It can be used in UDC drivers, especially in 'match_ep' callback after moving chip-specific endpoint matching logic from epautoconf to UDC drivers. Replace all calls of find_ep() function with gadget_find_ep_by_name(). Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-08-06usb: gadget: move ep_matches() from epautoconf to udc-coreRobert Baldyga2-84/+80
Move ep_matches() function to udc-core and rename it to usb_gadget_ep_match_desc(). This function can be used by UDC drivers in 'match_ep' callback to avoid writing lots of repetitive code. Replace all calls of ep_matches() with usb_gadget_ep_match_desc(). Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-08-06usb: gadget: add 'ep_match' callback to usb_gadget_opsRobert Baldyga1-0/+6
Add callback that is called by epautoconf to allow UDC driver match the best endpoint for specific descriptor. It's intended to supply mechanism which allows to get rid of chip-specific endpoint matching code from epautoconf. If gadget has set 'ep_match' callback we prefer to call it first, and if it fails to find matching endpoint, then we try to use default matching algorithm.

2015-08-05usb: ehci-platform: Fix using multiple controllers from OFAlban Bedel1-4/+9
When using OF defined controllers the platform data struct is shared between all devices, so it can't be used for device specific settings. However it is currently used for the OF properties needs-reset-on-resume and has-transaction-translator. To fix this issue move setting hcd->has_tt to the probe and move pdata->reset_on_resume to the private data.

2015-08-04usb: gadget: epautoconf: remove ep and desc configuration from ep_matches()Robert Baldyga1-32/+34
As function ep_matches() is used to match endpoint with usb descriptor it's highly unintuitive that it modifies endpoint and descriptor structures fields. This patch moves code configuring ep and desc from ep_matches() to usb_ep_autoconfig_ss(), so now function ep_matches() does nothing more than its name suggests.

2015-08-04usb: gadget: epautoconf: remove pxa quirk from ep_matches()Robert Baldyga2-11/+3
The same effect can be achieved by using capabilities flags, so now we can get rid of handling of hardware specific limitations in generic code. Signed-off-by: Robert Baldyga <r.baldyga@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-08-04usb: gadget: epautoconf: add endpoint capabilities flags verificationRobert Baldyga1-66/+30
Introduce endpoint matching mechanism basing on endpoint capabilities flags. We check if endpoint supports transfer type and direction requested in ep descriptor. Since we have this new endpoint matching mechanism there is no need to have old code guessing endpoint capabilities basing on its name, so we are getting rid of it. Remove also the obsolete comment.
