* usb: imx-us-phy: implement notify_(dis)concectSascha Hauer2016-09-291-0/+27
| | | | | | | | | | | The i.MX6 USB phy does not recognize disconnects of high speed devices when the USBPHY_CTRL_ENHOSTDISCONDETECT is not set. The phy does not work properly though when this bit is always set, so implement the notify_(dis)concect() callbacks to set this bit whenever a high speed device is connected and to clear it again when the device is disconnected.

* | fix erasing/protecting flashes with unspecified sizeSascha Hauer2016-04-192-3/+3
|/ | | | | | | | | | | | | | | | | fixes: 81737c1 mtd: Fix erasing of devices >4GiB Several places erased a complete flash partition passing ~0 as count to erase(). With the above commit count to erase was changed from an unsigned type to a signed type, so the (count > f->size - offset) check in erase() no longer triggers and the ~0 count is no longer adjusted to the whole device size. Among other things this results in saveenv failures on NOR flashes. This patch fixes this by introducing an explicit macro for erasing the whole device which is tested for in erase(). All other negative values are rejected. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reported-by: Giorgio <giorgio.nicole@arcor.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | In Linux ehci-q Data Toggle Control bit for interrupt transactions is preserved in Queue Head (EHCI 3.6.2). So don't set 14's bit in qh_endpt1 and don't manage toggle bit anywhere in int transactions.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | Currently all fastboot flash commands with UBI images are handled by a final call to 'ubiformat'. This only makes sense for flash commands where the target file is a mtd device. If we just want to transfer a UBI image we would expect a simple copy to the correct location. This patch checks if the destination file is a MTD device by opening it and calling an ioctl MEMGETINFO. Only for MTD devices, ubiformat is called.

On the big-endian machines extra le16_to_cpu() conversion leads to wrong idVendor/idProduct USB device parameters values (e.g. see devinfo <usb-device> output), and to a much more serious problem: idVendor/idProduct-based USB device detection does not work.
