2014-11-03usb: gadget: pxa27x_udc: fix clock prepare and enableRobert Jarzmik1-21/+5
As the udc clock controls both the output signals and the internal IP, it must be enabled before any UDC register is touched. The bug is revealed when the clock framework disables the clock for a couple of milliseconds during the boot sequence, and the endpoint configuration is lost. The bug is hidden when clock framework is not used, because no "unused clocks disable" occurs. This patch fixes the wrong behaviour by ensuring that : - whenever a UDC register is read or written, the clock is enabled - reworks the endpoints programming to have it done under running clock - reworks suspend/resume to ensure the same thing Signed-off-by: Robert Jarzmik <robert.jarzmik@free.fr> Signed-off-by: Felipe Balbi <balbi@ti.com>

2014-11-03usb: gadget: remove unnecessary 'driver' argumentFelipe Balbi26-83/+47
now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga <r.baldyga@samsung.com> which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.
