PMI8996 charger does not detect FLOAT adapter. To support it,
FLOAT detection is done by the USB driver and notified to PMIC
by reporting -ETIMEDOUT through the CURRENT_MAX power-supply
property. Charger then configures the charge current to 1500mA.

set_page_dirty() is racy if the caller has no
reference against page->mapping->host, and if
the page is unlocked. This is because another
CPU could truncate the page off the mapping and
then free the mapping.
Use set_page_dirty_lock() to avoid this race condition.

In some cases when connecting to a test fixture the host port
might not have triggered a connect change. As a result, dev->portnum
does not get updated and an attempt to enable the port for
compliance mode will pass 0 as the port number to the HCD, which is
invalid. Instead allow the user to pass an explicit port number
from the command line to specify the port to act on. Otherwise, if
omitted, the behavior is the same as before.

Add support for the SuperSpeed Link Layer test case TD.7.34
which requires the operator to place the port into compliance
mode, and to subsequently bring it out via reset. Historically
according to the (now deprecated) USB 3.0 specification a
SuperSpeed host downstream port would automatically transition
to Compliance mode from the Polling state if LFPS polling times
out. However the language in USB 3.1 as well as xHCI 1.1 states
it may be required to explicitly enable this transition. For
such hosts this is done by sending a SET_FEATURE(PORT_LINK_STATE)
with the state set to Compliance to the root hub port.
Similar to the other supported commands, to do this via sysfs:
echo > /sys/bus/usb/devices/2-0\:1.0/enable_compliance
According to xHCI 1.1 section 4.19.1.2.4.1, this enables the
transition to compliance mode upon LFPS timeout. Note that this
can only be issued when the port is in disconnected state. And
in order to disable this behavior on subsequent transitions, a
warm reset should be issued. So add another entry to do that:
echo > /sys/bus/usb/devices/2-0\:1.0/warm_reset
In general these attributes can also be useful for other USB
SuperSpeed compliance tests such as electrical and eye diagram
testing which require CPn patterns to be transmitted.

To perform SuperSpeed compliance testing the port should first
be placed into compliance mode. For xHCI 1.0 and prior this
transition happens automatically when the port is in Training
and encounters an LFPS timeout. Thus running compliance tests
against a test appliance may simply just work by simply plugging
in to the downstream port.
However starting with xHCI 1.1 the transition from Polling.LFPS
to compliance mode may be disabled by default and needs to be
explicitly enabled by writing to the PLS field of the PORTSC
register, which sets an internal 'CTE' (Compliance Transition
Enabled) flag so that the port will perform the transition the
next time it encounters LFPS timeout. Whether this is disabled or
not is determined by the 'CTC' (Compliance Transition Capability)
bit in the HCCPARAMS2 capability register.
In order to allow a test operator to change this if needed, allow
a test driver (such as drivers/usb/misc/lvstest.c) to send a
SET_FEATURE(PORT_LINK_STATE) control message to the root hub to
update the link state prior to connecting to the port. Subsequently,
placing the port in warm reset would then disable the flag.
