  further down the road).

  There is a 300-patch series waiting in the wings to get set out to
  subsystem maintainers, but these changes need to be present in the
  kernel first. Since this has some treewide changes, I carried this
  series for -next instead of paining Thomas with it in -tip, but it's
  got his Ack.

  This is similar to the timer_struct modernization from a while back,

 omap platforms.
 
 The main notable changes are for the Samsung Exynos platform, which
 sees a rewrite of gpio handling and a change to restore and adds
 a workaround for a problem with cpuidle support.

Paul Cercueil e3ee0e740c usb: common: usb-conn-gpio: Register charger
Register a power supply charger, whose online state depends on whether
the USB role is set to device or not.

This is useful when the USB role is the only way to know if the device
is charging from USB. The API is the standard power supply charger API,
you get a /sys/class/power_supply/xxx/online node which tells you the
state of the charger.

The sole purpose of this is to give userspace applications a way to
know whether or not the charger is plugged.

I've confirmed that the ASMedia ASM1142 has the same problem as the
ASM2142/ASM3142, in that it too reports that it supports 64-bit DMA
addresses when in fact it does not. As with the ASM2142/ASM3142, this
can cause problems on systems where the upper bits matter, and adding
the XHCI_NO_64BIT_SUPPORT quirk completely fixes the issue.

The tcpm.c code for sending VDMs assumes that there will only be one VDM
in flight at the time. The "queue" used by tcpm_queue_vdm is only 1 entry
deep.

This assumes that the higher layers (tcpm state-machine and alt-mode
drivers) ensure that queuing a new VDM before the old one has been
completely send (or it timed out) add a WARN_ON to check for this.

Hans de Goede a37241d834 usb: typec: tcpm: Fix AB BA lock inversion between tcpm code and the alt-mode drivers
When we receive a PD data packet which ends up being for the alt-mode
driver we have the following lock order:

1. tcpm_pd_rx_handler take the tcpm-port lock
2. We call into the alt-mode driver which takes the alt-mode's lock

And when the alt-mode driver initiates communication we have the following
lock order:

3. alt-mode driver takes the alt-mode's lock
4. alt-mode driver calls tcpm_altmode_enter which takes the tcpm-port lock

This is a classic AB BA lock inversion issue.

With the refactoring of tcpm_handle_vdm_request() done before this patch,
we don't rely on, or need to make changes to the tcpm-port data by the
time we make call 2. from above. All data to be passed to the alt-mode
driver sits on our stack at this point, and thus does not need locking.

So after the refactoring we can simply fix this by releasing the
tcpm-port lock before calling into the alt-mode driver.

This fixes the following lockdep warning:

usb: chipidea: imx: get available runtime dr mode for wakeup setting
If runtime dr_mode is not dual-role, it doesn't need to enable ID
wakeup interrupt.
If runtime dr_mode is host, it doesn't need to enable VBUS
wakeup interrupt.
With these changes, the user will not get the unexpected wakeup
for single role use case. For example, the host-only use case at
Micro-AB port, the controller should not be waken up by only
plug in Micro-AB cable or the Micro-B cable with host.

usb: chipidea: add query_available_role interface
The glue layer may need to know current available role to do some
setting, eg, the wakeup setting. So we add ci_hdrc_query_available_role
for that.

Greg Kroah-Hartman e98ba8cc3f USB: changes for v5.9 merge window
CDNS3 got several improvements, most of which are non-critical fixes.
 DWC3 has a reset fix for the meson platform, while dwc2 has
 improvements for role switch on STM32MP15 SoCs.
 
 Apart from these, we have the usual set of non-critical fixes all over
 the place and support for new Ingenic SoC to their PHY driver.

Michael Grzeschik f5e46aa4a1 usb: dwc3: gadget: when the started list is empty stop the active xfer
When we have nothing left to be queued after handling the last trb
we have to stop the current transfer. This way we can ensure that
the next request will be queued with a new and valid timestamp
and will not directly run into an missed xfer.

Michael Olbrich c5a7092f40 usb: dwc3: gadget: make starting isoc transfers more robust
Currently __dwc3_gadget_start_isoc must be called very shortly after
XferNotReady. Otherwise the frame number is outdated and start transfer
will fail, even with several retries.

DSTS provides the lower 14 bit of the frame number. Use it in combination
with the frame number provided by XferNotReady to guess the current frame
number. This will succeed unless more than one 14 rollover has happened
since XferNotReady.

Start transfer might still fail if the frame number is increased
immediately after DSTS is read. So retries are still needed.
Don't drop the current request if this happens. This way it is not lost and
can be used immediately to try again with the next frame number.

With this change, __dwc3_gadget_start_isoc is still not successfully in all
cases bit it increases the acceptable delay after XferNotReady
significantly.
