Canceling hrtimer when holding uart spinlock can deadlock.
CPU0: syscall write
-> get uart port spinlock
-> write uart
-> start_tx_rs485
-> hrtimer_cancel
-> wait for hrtimer callback to finish
CPU1: hrtimer IRQ
-> run hrtimer
-> em485_handle_stop_tx
-> get uart port spinlock
CPU0 is waiting for the hrtimer callback to finish, but the hrtimer
callback running on CPU1 is waiting to get the uart port spinlock.
This deadlock can be avoided by not canceling the hrtimers in these paths.
Setting active_timer=NULL can be done without accessing hrtimer,
and that will effectively cancel operations that would otherwise have been
performed by the hrtimer callback.

With the timer converted to using the new timer_setup()/from_timer() API,
setting the .data field is redundant (and the field will be removed soon),
so drop it.

During hibernation, freeze/thaw/restore dev_pm_ops are called instead of
suspend/resume. Hook up the hibernation ops. The _noirq parts are
identical, but suspend/resume are replaced with variants that do not
enable wakeup from i.MX UART. There is no need to restore register
contents in thaw_noirq.

Back in 2010, commit 3b43816f685f ("ARM: 5933/1: amba-pl011: support
hardware flow control") added an autorts flag to this driver to store
whether automatic hardware flow control is requested.
In 2015, commit 391f93f2ec9f ("serial: core: Rework hw-assisted flow
control support") added a flag with identical functionality to generic
code.
Switch over to that flag and drop the driver-specific one.

This driver's ->rs485_config callback checks if SER_RS485_RTS_ON_SEND
and SER_RS485_RTS_AFTER_SEND have the same value. If they do, it means
the user has passed in invalid data with the TIOCSRS485 ioctl()
since RTS must have a different polarity when sending and when not
sending. In this case, rs485 mode is not enabled (the RS485_URA bit
is not set in the RS485 Enable Register) and this is supposed to be
signaled back to the user by clearing the SER_RS485_ENABLED bit in
struct serial_rs485 ... except a missing tilde character is preventing
that from happening.

The SCSCR register access in sci_break_ctl() is not locked.
sci_start_tx() and sci_set_termios() changes the SCSCR register,
but does not lock sci_port.
Therefore, this patch adds lock during register access.
Also, remove the log output that leads to a double lock.
Some analysis of where locks are not taken is as follows.
It appears that the lock is not taken in:
- sci_start_tx(), sci_stop_tx() as this is installed as a callback.
And all callers of the callback take the lock.
- start_rx as callers take the lock.
- stop_rx. this is both installed as a callback and called directly.
In both cases the caller takes the lock.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.

Sync events are sent by sparse_keymap_report_entry for normal KEY_*
events, and are generated by several drivers after generating
SW_* events, so sparse_keymap_report_entry should do the same.

Currently, no driver uses sparse-keymap for SW_* events, but
it is required for the intel-vbtn platform driver to generate
