* usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga2013-12-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

| | | | | | | | | | | | | | | r8a66597_sudmac_irq() r8a66597_irq() processes sudmac part (r8a66597_sudmac_irq()) before locking r8a66597->lock. But transfer_complete(), that is called inside (r8a66597_sudmac_irq()->sudmac_finish()->transfer_complete()), expects r8a66597->lock is locked. As a result unheld spinlock can be unlocked.

| | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | BUSWAIT is a 4-bit-wide value that controls the number of access waits from the CPU to on-chip USB module. b'0000 inserts 0 wait (2 access cycles) and b'1111 inserts 15 waits (17 access cycles, hardware initial value), respectively. BUSWAIT value depends on peripheral clock frequency supplied to on-chip of each CPU, hence should be configurable through platform data. Note that this patch assumes that b'0000 (0 wait, 2 access cycles) is rerely used and considered as invalid. If valid 'buswait' data is not provided by platform, initial b'1111 (15 waits, 17 access cycles) will be applied as a safe default.

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