Pull tty / serial driver updates from Greg KH:
 "Here is the big set of tty and serial driver changes for 6.0-rc1.

  It was delayed from last week as I wanted to make sure the last commit
  here got some good testing in linux-next and elsewhere as it seemed to
  show up only late in testing for some reason.

  Nothing major here, just lots of cleanups from Jiri and Ilpo to make
  the tty core cleaner (Jiri) and the rs485 code simpler to use (Ilpo).

  Also included in here is the obligatory n_gsm updates from Daniel
  Starke and lots of tiny driver updates and minor fixes and tweaks for
  other smaller serial drivers.

  All of these have been in linux-next for a while with no reported
  problems"

 "There are three independent sets of changes:

   - Sai Prakash Ranjan adds tracing support to the asm-generic version
     of the MMIO accessors, which is intended to help understand

     kernels for many years

   - A patch from Sebastian Siewior to rework the handling of IRQ stacks
     in softirqs across architectures, which is needed for enabling
     PREEMPT_RT

   - The last patch to remove the CONFIG_VIRT_TO_BUS option and some of

     made it in through the netdev, scsi, media and staging trees"

When we multiply an unsigned int by a u32 we still end up with an
unsigned int. That means we should specify "%u" not "%lu" in the
format code.

NOTE: this fix was chosen instead of somehow promoting the value to
"unsigned long" since the max baud rate from the earlier call to
uart_get_baud_rate() is 4000000 and the max sampling rate is 32.
4000000 * 32 = 0x07a12000, not even close to overflowing 32-bits.

   - Improved support for BCM2711 (Raspberry Pi 4) power management to
     allow the use of the V3D GPU

   - Cleanups to the NXP guts driver

   - Arm SCMI firmware driver updates to add tracing support, and use
     the firmware interfaces for system power control and for power
     capping"

This was the only function mentioned in the text, but was neither linked
nor documented. So document and link it, so that hyperlinking works in
the text.

There are many annotated functions in serial_core.c, but they do not
completely conform to the kernel-doc style. So reformat them and link
them from the Documentation.

The GPIO uart functions are documented in Documentation. Move and
transform this documentation into kernel-doc directly in the code and
reference it in Documentation using kernel-doc:.

This makes it easier to update, maintain and check by the build.

Some of the serial (uart_*) functions are documented twice. Once as
kernel-doc along their sources and once in Documentation. So deduplicate
these texts, merge them into kernel-doc in the sources, and link them
using kernel-doc: from the Documentation.

To be properly linked and rendered, tabulators had to be removed from
the comments.
