flush_scheduled_work() in tty_exit() doesn't seem to target any
specific work. If it was to flush work items used in tty generic
layer, they're already flushed properly during tty release.
flush_scheduled_work() is going away. Remove the seemingly redundant

CPU0 and CPU1 clockdomain is at the offset of 0x18 from the LPRM base.
The header file has set it wrongly to 0x0. Offset 0x0 is for CPUx power
domain control register
Fix the same.
The autogen scripts is fixed thanks to Benoit Cousson
With the old value, the clockdomain code would access the
*_PWRSTCTRL.POWERSTATE field when it thought it was accessing the
*_CLKSTCTRL.CLKTRCTRL field. In the worst case, this could cause
system power management to behave incorrectly.

When a driver doesn't know how much data a device is going to send,
the buffer size should be at least as big as the endpoint's maxpacket
value. The serial drivers don't follow this rule; many of them
request only 256-byte bulk-in buffers. As a result, they suffer
overflow errors if a high-speed device wants to send a lot of data,
because high-speed bulk endpoints are required to have a maxpacket
size of 512.
This patch (as1450) fixes the problem by using the driver's
bulk_in_size value as a minimum, always allocating buffers no smaller
than the endpoint's maxpacket size.

The USB stack historically has conflated device numbers (i.e., the
value of udev->devnum) with device addresses. This is understandable,
because until recently the two values were always the same.
But with USB-3.0 they aren't the same, so we should start calling
these things by their correct names. This patch (as1449b) changes many
of the references to "address" in the hub driver to "device number"
or "devnum".
The patch also removes some unnecessary or misleading comments.

For level type interrupts we need to track how many threads are on
flight to avoid useless interrupt storms when not all thread handlers
have finished yet. Keep track of the woken threads and only unmask
when there are no more threads in flight.
Yes, I'm lazy and using a bitfield. But not only because I'm lazy, the
main reason is that it's way simpler than using a refcount. A refcount
based solution would need to keep track of various things like
crashing the irq thread, spurious interrupts coming in,
disables/enables, free_irq() and some more. The bitfield keeps the
tracking simple and makes things just work. It's also nicely confined
to the thread code pathes and does not require additional checks all
over the place.
