Hi Maxim, unfortunately we cannot test the latest kernel right now, because we have custom drivers and additional changes that need to be ported, but the MUSB driver in our kernel should contain all fixes from

[PATCH 01/14] usb: dwc2: Rename hibernation to partial_power_down

From: Vardan Mikayelyan No-op change, only rename. This code was misnamed originally. It was only responsible for partial power down and not for hibernation. Rename core_params->hibernation to core_params->power_down, dwc2_set_param_hibernation() to

[PATCH 03/14] usb: dwc2: gadget: Moved dtxfsiz backup array place

From: Vardan Mikayelyan Moved dtxfsiz from dwc2_gregs_backup to dwc2_dregs_backup, because it is device register. Signed-off-by: Vardan Mikayelyan Signed-off-by: John Youn Signed-off-by: Grigor Tovmasyan

[PATCH 09/14] usb: dwc2: Add host/device hibernation functions

From: Vardan Mikayelyan Add host/device hibernation functions which must be wrapped by core's dwc2_enter_hibernation()/dwc2_exit_hibernation() functions. Make dwc2_backup_global_registers dwc2_restore_global_register non-static to use them in both host/gadget sides.

[PATCH] USB: gadget: function: remove redundant initialization of 'tv_nexus'

From: Colin Ian King Pointer tv_nexus is being initialized a value and this is never read and is later being updated with the same value. Remove the redundant initialization so that the assignment to tv_nexus is performed later and more local to when it is being read.

how to disable a xhci logical port?

Hi, A xHCI controller has two logical ports, hs and ss port. Is it possible to disable one port, for example the ss port? If so, how? By disable, I meant the xHCI driver doesn't see the port when the xHCI driver is loaded and doesn't create that usb bus. Thanks, -Bin. -- To unsubscribe from
