USB controller registers can be accessed when USB session
is not active or USB is in low power mode. This results
in unclocked register access. Prevent this by checking
the USB LPM status before accessing the registers.

If cable disconnects before data stage completion dwc3_remove_requests()
gets called for ep0 in and out but dwc3_ep0_complete_data() does not
get called. dwc3_ep0_complete_data() function resets TRB enqueue count
to 0. As a result upon next cable connect start transfer is called with
wrong TRB address because trb_enqueue is set to 1. Since this TRB was
completed in the past, HWO bit is cleared for this TRB. This results into
usb enumeration failure due to control transfer stall. Fix this issue
by issuing end transfer command on control endpoints after ep0 requests
are removed for IN and OUT and reset trb_enqueue counters to 0.

Consider a case of quick pull-up disable after pull-up is enabled.
If a SETUP packet comes after bus reset event followed by connection
done event, there is a possibility of race between
composite_dev_cleanup() freeing cdev->req called from
configfs_composite_unbind() and composite_setup() storing req pointer
to stack. This causes use after free of cdev->req. Fix this issue by
disabling the irq before clearing the run-stop bit so that interrupt
handling for setup packet is prevented. In order to prevent running
bottom half check pullups_connected flag in dwc3_interrupt and ack
the generated events and return. Also flush the bottom half work
if there was any work pending before disabling dwc3 irq.

debugfs_create_dir() returns NULL when second directory is created
with same name gsi-epin. Without checking return value
dwc3_debugfs_create_endpoint_dir() creates endpoint files with parent
as NULL. This would create files in root dir /sys/kernel/debug which
remains there even after calling debugfs_remove_recursive() from
dwc3_debugfs_exit(). Due to probe deferral dwc3 endpoints get freed
up and re-allocated. As a result accessing endpoint files created in
root dir causes access to stale dwc3 endpoint pointer. Hence check
return value for debugfs_create_dir and do not create files for NULL
parent.

When dwc3_gadget_pullup() is called to perform a device-initiated
disconnect, the driver must ensure that no transfers are in progress
before clearing the run/stop bit. Currently there is a check which
ensures ep0 is in EP0_SETUP_PHASE and if not simply waits for any
pending control transfer to conclude and return to that initial state.
However, since this is done before the dwc->lock is acquired, this
allows for a race in which a new ep0 transfer gets started and we
receive another SETUP packet from the host before proceeding to take
the lock.
To fix this, simply don't allow a new ep0 transfer to start if
dwc->softconnect is false.

DWC3 driver uses wakeup_source and allows pm_suspend only after
entering low power mode as part of runtime suspend. This prevents
PM suspend in host mode if connected device's driver doesn't
support runtime or selective suspend.
For platforms such as automotive, add support in driver where
user can specify using dtsi attribute to not use wakeup source in
host mode. It will allow system to enter deep sleep or pm_suspend
irrespective of runtime PM state of XHCI. The connected devices
are also reset-resumed on PM resume.
On high level below are the changes in default behavior:
-Do not use wakeup_source for DWC3 when operating in host mode.
-For host mode, devices will suspend upon PM suspend and
reset-resumed on PM resume.

There is possible race between pull up disable vs ep_queue() API.
Pull up disable sends END transfer command to per endpoint, and give
back started request and pending request back to function driver.
dwc3_gadget_giveback() API does release spinlock which may allow
ep_queue() or completion handling to queue next request. This results
into TRB pending without invoking end transfer command, whereas request
is being given back to function driver and being freed. Hence on setting
next pull up enable, USB controller accesses previous stale TRB causing
unmapped page fault. Fix this issue by checking pull up disable or not
while handling ep_queue().

There is a possibility of race between endpoint transfer
completion context and stop active transfer context. As

dwc3_remove_requests() is deleting req from started list.
While iterating over current list node list_for_each_safe caches
next list node. If the cached list node is getting deleted by
dwc3_remove_requests() then request for same list node would be
given back as part of endpoint transfer completion. This result
into list_del corruption because list node is getting deleted
twice. Fix this issue by iterating started_list using while loop
and always accessing first node from list head.

There still exists a small window in which dwc3_gadget_pullup()
is called while a new control transfer setup packet had newly
arrived. In the case where it needs to be delegated to the gadget
driver, it releases dwc3->lock and allows pullup() to proceed to
call run_stop() to attempt to stop the controller. The lock will
get released again when calling dwc3_stop_active_transfers()
which allows the gadget driver to meanwhile call ep_queue() for
a three-stage control transfer and sneak in a Start Transfer. By
the time the DCTL register is written, the controller will fail
to halt due to having an outstanding transfer in progress.

This reverts commit e070355664, reversing
changes made to 8808cf8cbc.
Introducing symbol-namespaces into the kernel has caused issues with
respect to the ABI checker. Hence, revert the changes until a valid
fix is available. The revert was done based off of 5.4-rc1.

Since we don't do energy-aware wakeups when we are overutilized, always
honoring sync wakeups in this state does not prevent wake-wide mechanics
overruling the flag as normal.
Having the check for (cpu_rq(cpu)->nr_running == 1) in the test condition
means that we only bypass the energy model for sync wakeups where the
cpu is about to become idle. This matches the use of this flag in Binder
which is the main place where sync wakeups come from in Android.
This patch is based upon previous work to build EAS for android products.
It replaces
commit 79e3a4a27e ("ANDROID: sched: Unconditionally honor sync flag
for energy-aware wakeups")
in what's considered to be 'EAS'.

The generic kernel image must have module signing disabled so it can
load kernel modules from all vendors. Unfortunately loading a signed
kernel module into a kernel with module signing disabled will fail
because struct module_layout (which appears in kernel modules) contains
struct module, and struct module contains the sig_ok field, which is
conditionally compiled depending on CONFIG_MODULE_SIG (module signing).
Unconditionally compile the sig_ok field to work around this problem.

Soc framework exposed sysfs entries are not sufficient for some
of the h/w platforms. Currently there is no interface where soc
drivers can expose further information about their SoCs via soc
framework. This change address this limitation where clients can
pass their custom entries as attribute group and soc framework
would expose them as sysfs properties.
