usb: gadget: fotg210: EP0 fifo empty indication is non-reliable

2014-01-13T11:15:13Z

The fifo size of ep0 is 64 bytes, and if the packet size grater than 64 bytes, the driver would have to fill up the fifo multiple times, and before filling up the fifo, the driver should make sure the fifo is empty by checking fifo empty indication. However there is a hardware bug that the fifo empty indication is somehow a bit earlier than fifo reset. So if I don't add an extra delay here, the data might be corrupted. (i.e., 1 byte missing) After a couple of tests, it truns out that 1 usec is good enough. This workaround should be applied to all hardware revisions. Signed-off-by: Kuo-Jung Su CC: Marek Vasut

usb: gadget: fotg210: add w1c interrupt status support

2014-01-13T11:15:12Z

Since hardware revision 1.11.0, the following interrupt status registers are now W1C (i.e., write 1 clear): 1. Interrupt Source Group 0 Register (0x144) (EP0 Abort: BIT5) 2. Interrupt Source Group 2 Register (0x14C) (All bits) And before revision 1.11.0, these registers are all R/W. Which means software must write a 0 to clear the status.

usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout value

2013-12-18T18:53:19Z

It is necessary to deter the host from sending subsequent DFU_GETSTATUS request in the case of e.g. writing the buffer to medium. Here the timeout is increased when we fill up the whole buffer. This delay allows eMMC memory to perform its internal operations. Otherwise we end up with HOST's error regarding GET_STATUS receive timeout. Signed-off-by: Lukasz Majewski

drivers/usb/gadget: select objects by obj-$(CONFIG-...)

2013-12-13T14:18:44Z

Before switching to the real Kbuild, drivers/usb/gadget/Makefile must be fixed. If none of CONFIG_USB_GADGET, CONFIG_USB_ETHER, CONFIG_USB_DEVICE is defined, both obj- and obj-y get empty. We need non-empty obj- or obj-y on each Makefile to generate built-in.o on the real Kbuild. Signed-off-by: Masahiro Yamada

usb, g_dnl: make bcdDevice value configurable

2013-11-12T14:53:59Z

add the possibility to set the bcdDevice number board specific. Therefore the weak function g_dnl_get_board_bcd_device_number() is introduced. Used on the siemens boards. Signed-off-by: Heiko Schocher Acked-by: Lukasz Majewski Cc: Marek Vasut Cc: Kyungmin Park

usb, g_dnl: make iSerialNumber board configurable

2013-11-08T19:46:20Z

add the possibility to set the iSerialNumber board specific. Default value for iSerialNumber is 0x0. This value can changed board specific through the new function g_dnl_set_serialnumber() which must be called from the board specific function g_dnl_bind_fixup().

usb: ums: add ums exit feature by ctrl+c or by detach usb cable

2013-11-08T19:46:19Z

This patch allows exiting from UMS mode to u-boot prompt by detaching usb cable or by pressing ctrl+c. Add new config: CONFIG_USB_CABLE_CHECK. If defined then board file should provide function: usb_cable_connected() (include/usb.h) that return 1 if cable is connected and 0 otherwise. Changes v2: - add a note to the README Signed-off-by: Przemyslaw Marczak Cc: Marek Vasut

usb: ums: fix disk capacity miscalculation and code cleanup

2013-11-08T19:46:19Z

This patch prevents: - ums disk capacity miscalculation because of integer overflow Changes v2: - Prevents passing zero size disk capacity to ums gadget driver - Change function ums_get_capacity() to ums_disk_init() and do ums disk initialization before gadget init - Remove unnecessary code from mass storage driver Signed-off-by: Przemyslaw Marczak Cc: Marek Vasut
