We do *not* want to touch devctl at all when
trying to recover from babble. All we want to
do is mask IRQs until we're done without our
babble recovery, at which point we will unmask
IRQs.

sometimes we want to just mask/unmask interrupts
without touching devctl register. For those
cases, let's introduce musb_enable_interrupts and
musb_disable_interrupts()

Whenever babble happens, MUSB controller will
drop session automatically.
The only case where it won't drop the session,
is when we're running on AM335x and SW_SESSION_CTRL
bit has been set. In that case, controller will
not touch session bit so SW has a chance to recover
from babble condition.

We want to check if that particular bit is
set. It could very well be that bootloader
(or romcode) has fiddled with MUSB before
us which could leave other bits set in this
register.

musb->int_usb already contains the correct
information for musb-core to handle babble.
In fact, this very check was just causing a
nonsensical babble interrupt storm.
With this I can get test.sh to run and, even though
all tests fail with timeout, that's still better
than locking up the system due to IRQ storm.
Also, if I remove g_zero and load g_mass_storage,
then everything works fine again.

when musb is operating as host and a remote wakeup

RESUME bit is automatically set.

As per the SAF1761 data sheet[0], the DcChipID register represents
the hardware version number (0001h) and the chip ID (1582h) for the
Peripheral Controller.
However as per the ISP1761 data sheet[1], the DcChipID register
represents the hardware version number (0015h) and the chip ID (8210h)
for the Peripheral Controller.
This patch adds support for both the chip ID values.

This patch fixes a bug where removing dwc3-omap.ko
would not trigger removal of dwc3.ko.
of_platform_depopulate() already bakes an easy to
use API for removing all our children which were
populated during probe(); Let's use that one instead
of cooking our own solution.
Note that this is kind of a revert of commit c5a1fbc
(usb: dwc3: dwc3-omap: Fix the crash on module removal)
although we can't simply revert that because a direct
call to platform_device_unregister would also be flakey.

That trick is only needed if we end up with an error, so
there's no point in messing that outside of an error path.

instead of using manually spelled out bit-shits
and iterate over each of the 16-bits (one for
each endpoint) on each direction, we can make use
of for_each_set_bit() which internally uses
find_first_bit().
This makes the code slightly more readable while
also making we only iterate over bits which are
actually set.

Currently tty_wait_until_sent may take up to twice as long as the
requested timeout while waiting for driver and hardware buffers to
drain.
Fix this by taking the remaining number of jiffies after waiting for
driver buffers to drain into account so that the timeout actually
becomes a maximum timeout as it is documented to be.
Note that this specifically implies tighter timings when closing a port
as a consequence of actually honouring the port closing-wait setting
for drivers relying on tty_wait_until_sent_from_close (e.g. via
tty_port_close_start).

Fix overflow bug in tty_wait_until_sent on 64-bit machines, where an
infinite timeout (0) would be passed to the underlying tty-driver's
wait_until_sent-operation as a negative timeout (-1), causing it to
return immediately.
This manifests itself for example as tcdrain() returning immediately,
drivers not honouring the drain flags when setting terminal attributes,
or even dropped data on close as a requested infinite closing-wait
timeout would be ignored.
The first symptom was reported by Asier LLANO who noted that tcdrain()
returned prematurely when using the ftdi_sio usb-serial driver.
Fix this by passing 0 rather than MAX_SCHEDULE_TIMEOUT (LONG_MAX) to the
underlying tty driver.
Note that the serial-core wait_until_sent-implementation is not affected
by this bug due to a lucky chance (comparison to an unsigned maximum
timeout), and neither is the cyclades one that had an explicit check for
negative timeouts, but all other tty drivers appear to be affected.

This problem was taken care of three times already in

* b0b885657b6c8ef63a46bc9299b2a7715d19acde (tty: fix up atime/mtime
mess, take three)
But it still misses one point. As John Paul correctly points out, we
do not care about setting date. If somebody ever changes wall
time backwards (by mistake for example), tty timestamps are never
updated until the original wall time passes.
So check the absolute difference of times and if it large than "8
seconds or so", always update the time. That means we will update
immediatelly when changing time. Ergo, CAP_SYS_TIME can foul the
check, but it was always that way.

Fixed behaviour of get_mctrl() serial driver function as documented in:
https://www.kernel.org/doc/Documentation/serial/driver
Added device-tree properties 'dcd-override', 'dsr-override',
'cts-override', and 'ri-override' specific to the Synopsis 8250
DesignWare UART driver. Allows one to force Data Carrier Detect,
Clear To Send, and Data Set Ready signals to permanently be reported as
active. The Ring indicator can be forced to be reported as inactive.
It is possible that if modem control signalling is enabled on a port
that doesn't have these pins (e.g. - a simple two wire Tx/Rx port), the
driver can hang indefinitely waiting for the state to change. The new
DT properties allow the driver to ignore the state of these pins on
serial ports that don't support them, as recommended in the kernel
documentation.
