This patch adds Multi Count support. It adds few modifications: - Fix s3c_hsotg_set_ep_maxpacket() function. Field wMaxPacketSize of endpoint descriptor is now splitted into maximum packet size value and number of additional transaction per microframe. - Modify s3c_hsotg_write_fifo() function. It actually calculates transfer size, taking into account Multi Count value, which indicates number of transactions per microframe. - Fix s3c_hsotg_start_req() function by setting number of packets to Multi Count field in DIEPTSIZ register for isochronous endpoints.

This patch adds isochronous transfer support. It adds few modifications: - Modify s3c_hsotg_epint() function. Some interrupts are ignored for isochronous endpoints, (e.g. INTknTXFEmpMsk) becouse isochronous request is always transfered in single transaction, which ends with XferCompl interrupt. - Add Odd/Even microframe toggle to allow data transfering in each microframe in s3c_hsotg_epint() function. - Fix s3c_hsotg_ep_enable() function by supporting isochronous endpoint type.

This adds RCAR Gen2 USB phy support. The driver configures USB channels 0/2 which are shared between PCI USB hosts and USBHS/USBSS devices. It also controls internal USBHS phy. Signed-off-by:

Converting mass storage to the new function interface requires converting the USB mass storage's function code and its users. This patch converts the f_mass_storage.c to the new function interface. The file is now compiled into a separate usb_f_mass_storage.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by:

When configfs is in place, the luns will not be represented in sysfs, so there will be no struct device associated with a lun. In order to maintain compatibility and allow configfs adoption sysfs is made optional in this patch. As a consequence some debug macros need to be adjusted. Two new fields are added to struct fsg_lun: name and name_pfx. The "name" is for storing a string which is presented to the user instead of the dev_name. The "name_pfx", if non-NULL, is prepended to the "name" at printing time. The name_pfx is for a future lun.0, which will be a default group in mass_storage.<name>. By design at USB function configfs group's creation time its name is not known (but instead set a bit later in drivers/usb/gadget/configfs.c:function_make) and it is this name that serves the purpose of the said name prefix. So instead of copying a yet-unknown string a pointer to it is stored in struct fsg_lun. Signed-off-by:

This patch fixes max packet size check in s3c_hsotg_set_ep_maxpacket() function. According USB specification, bits 10..0 of mps specifies maximum packet size, so there is bitwise AND between mps and 0x7ff value. Also added check if maxpacket isn't grater than 1024 which is maximum size od single USB transaction. In s3c_hsotg_ep_enable() function added s3c_hsotg_set_ep_maxpacket() call instead of setting ep.maxpacket value directly. Signed-off-by:

This patch changes ep maxpacket value from 512 to 1024, because it's needed to handle interupt and isochronous endpoints in high-speed mode. This change doesn't affect on driver functioning, because fifo size (3072) is still enough for the maximum transaction payload (3*1024 for high-speed high-bandwidtch endpoints). Signed-off-by:
