* usb: gadget: ether set wMaxPacketSizeTroy Kisky2013-10-20-0/+2
| | | | | | | | | | | | | | | | | | | | | set wMaxPacketSize for full speed descriptors fs_source_desc, fs_sink_desc to 64. Full-speed bulk endpoint can have a maximum packet size of 8, 16, 32, or 64 bytes, so choice 64. The hs_source_desc, hs_sink_desc, already have their wMaxPacketSize set to 512. That is the only legal value for high speed bulk endpoints. Strictly speaking, this patch is not needed because usb_ep_autoconfig will call ep_matches which will override wMaxPacketSize for BULK endpoints only with the size associated with the endpoint setup by the udc driver. But if you want to rely on this, you may as well combine the full speed descriptor with the high speed descriptor to minimize confusion. Signed-off-by: Troy Kisky <troy.kisky@boundarydevices.com>

| | | | | | | | | | | | | | | (f_mass_storage) The mass storage composite function is now compiled in only when CONFIG_USB_GADGET_MASS_STORAGE is defined. Such change provides binary size reduction for boards which use USB download gadget (like am335x_evm) with DFU, but don't use UMS. For example at am335x_evm board reduction is more than 2KiB for text and around 120B for data. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>

| | | | | | | | | | | | | | | | | | | | The usb_lowlevel_init() call already fills and passes back struct ehci_ctrl , which readily contains correctly determined address of the port register block address computed from values from controller configuration registers. Leverage this and make use of this value as this makes the code mode universal, but also gets us rid of the CONFIG_USB_REG_BASE configuration option. Moreover, this patch cleans up the usb_gadget_register_driver() call a little by correcting the error handling. Note the usb_lowlevel_init() and mvudc_probe() are now called in reversed order, but this has no impact on the code.
