The kernel now has a number of testing and debugging tools, and we've
seen a bit of confusion about what the differences between them are.
Add a basic documentation outlining the testing tools, when to use each,
and how they interact.
This is a pretty quick overview rather than the idealised "ker
When core is in hibernation state and an external
hub is connected, upper layer sends URB enqueue request,
which results in port reset issue.
- Added exit from hibernation state to avoid port
reset issue and process upper layer request properly.

This move is done to call hibernation exit handler in
"dwc2_port_resume()" function when core receives port resume.
Otherwise it could be confusing to exit hibernation in
"dwc2_hcd_hub_control()" function but other power saving modes
in "dwc2_port_resume()" function.

When hibernation exit is performed the dwc2_hib_restore_common()
function is called. In that function we wait until GINTSTS_RESTOREDONE

No need to check for "DWC2_POWER_DOWN_PARAM_HIBERNATION" param
as "hsotg->hibernated" flag is already enough for exiting from
hibernation mode.
- Removes checking of "DWC2_POWER_DOWN_PARAM_HIBERNATION" param.
- For code readability Hibernation exit code moved after
debug message print.
- Added "
Initially resetting device address was done in dwc2_hsotg_irq()
interrupt handler. However, when core is hibernated USB RESET
is not handled in dwc2_hsotg_irq() handler, instead USB RESET
interrupt is handled in dwc2_handle_gpwrdn_intr() handler.
- Added reset device address to zero when core exit

Having been confused by this for a case in the past, thanks! It'd be
nice for code coverage's sake to have a shell test on this.
