When adb root is performed, userspace will close and open ffs_epsfile.
Closing this file will call ffs_functionfs_callback() which does call
remove_config(). This will call ffs_function_eps_disable to disable
endpoints and then calls ffs_func_unbind(). Unbind() will also call
endpoint disable which might lead to disabling endpoint which is already
disabled. Hence set ffs->func to NULL after disabling endpoints in
set_alt().

Normally in epfile_io() and epfile_ioctl(), if the endpoint is
not enabled the system call will block waiting until the endpoint
is enabled. During a USB disconnect, the function's endpoints get
disabled, so that if an IO call occurs right after that, it would
perform the same blocking wait. From the kernel perspective this
is indistinguishable from an IO call happening after the function
is first initialized but not yet enabled. Hence a userspace
process would be blocked and unaware of the cable disconnection.
For userspace daemons such as ADB, this can be a problem since its
read/write threads cannot be reaped until the I/O call returns,
which won't happen until the cable is reconnected. In that case,
the previous pending read/write would proceed to get successfully
queued. In the case of a read, the previous read consumes data
meant for the new session, and in the case of a write, stale data
could be sent to the host.
To fix this, add a counter to keep track of the epfile's open status.
Upon the endpoint getting disabled mark the endpoint as invalid so as
to fail subsequent IOs until the epfile is fully closed. Returning
-ENODEV upon failure should allow the userspace process to close the
file, so that it can reopen and begin a new session.

PCIe internal AUX clock frequency used to be either 1MHz or
19.2MHz. The devicetree entry was a boolean type to determine
which frequency to program in PCIe controller. Newer chipsets
may support other frequencies such as 16.6MHz. Update the
devicetree entry so that it accepts a decimal value for the
desired frequency to be programmed in PCIe controller.

subsystem like TZ. So poll the CX GDSCR register to ensure that CX has
indeed collapsed.
