This patch adds sysfs "otg_inputs" for usb role swap. This parameter
is write-only and if you use them as the following, you can swap
the usb role.
For example:
1) connect a usb cable using 2 salvator-x boards
2) On A-device (as host), you input the following command:
# echo a_bus_req/ > /sys

Make sure to drop the references taken by of_parse_phandle() and
bus_find_device() before returning from am335x_get_phy_control().
Note that there is no guarantee that the devres-managed struct
phy_control will be valid for the lifetime of the sibling phy device
regardless of this change.

This subsystem consistently fails to drop the device reference taken by
class_find_device().
Note that some of these lookup functions already take a reference to the
returned data, while others claim no reference is needed (or does not
seem need one).

According to Dave Miller "the networking stack has a
hard requirement that all SKBs which are transmitted
must have their completion signalled in a fininte
amount of time. This is because, until the SKB is
freed by the driver, it holds onto socket,
netfilter, and other subsystem resources."

Hello all,
I am the developer of the ShipModul (CustomWare) MiniPlex products where
we use FTDI chips for USB communications.
I see that even the latest PID we use (FD4B) is already in the

Hello,
Coming back to this old thread. I enabled the xhci debug, with little success.
I am running now kernel 4.8.4; there is no dmesg dump anymore, the
system just reboots by itself.
As I am running kernel crash dump, the system loads the kdump kernel,
but doesn't find anything to save.

This suppresses printing the error message "failed to get phy" in the
