由 Boris BREZILLON 提交于
The AT91 PMC (Power Management Controller) provides an USB clock used by USB Full Speed host (ohci) and USB Full Speed device (udc). The usb drivers (ohci and udc) must configure this clock to 48Mhz. This configuration was formely done in mach-at91/clock.c, but this implementation will be removed when moving to common clk framework. This patch adds support for usb clock retrieval and configuration, and is backward compatible with the current at91 clk implementation (if usb clk is not found, it does not configure/enable it).

Earlier we used to check for ep->ep.desc to figure out if this ep has already been enabled and if so, abort. Ido Shayevitz removed the usb_endpoint_descriptor from private udc structure 5a6506f0 ("usb: gadget: Update at91_udc to use usb_endpoint_descriptor inside the struct usb_ep") but did not fix up the ep_enable condition because _now_ the member is always true and we can't check if this ep is enabled twice.

This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

peripheral drivers are using usb_add_gadget()/usb_del_gadget() to register/unregister to the udc-core.
