378ec25aec Merge tag 'tty-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty
Pull tty/serial updates from Greg KH:
 "Here is the big set of tty and serial driver changes for 6.16-rc1.

  A little more churn than normal in this portion of the kernel for this
  development cycle, Jiri and Nicholas were busy with cleanups and
  reviews and fixes for the vt unicode handling logic which composed
  most of the overall work in here.

  Major changes are:

   - vt unicode changes/reverts/changes from Nicholas. This should help
     out a lot with screen readers and others that rely on vt console
     support

   - lock guard additions to the core tty/serial code to clean up lots
     of error handling logic

   - 8250 driver updates and fixes

   - device tree conversions to yaml

   - sh-sci driver updates

   - other small cleanups and updates for serial drivers and tty core
     portions

  All of these have been in linux-next for 2 weeks with no reported issues"

857eec4678 dt-bindings: serial: 8250_omap: Drop redundant properties
The binding references in-kernel serial.yaml, so there is no need to
explicitly list its properties.  Note that rts-gpio is also redundant
because DTS should be simply converted to -gpios variants.

RSCI of RZ/T2H SoC (a.k.a r9a09g077), as a lot
of similarities with SCI in other Renesas SoC like G2L, G3S, V2L;
However, it has a different set of registers, and in addition to serial,
this IP also supports SCIe (encoder), SmartCard, i2c and spi.
This is why the 'renesas,sci' fallback for generic SCI does not apply for it.

4dd7c9d948 dt-bindings: serial: sc16is7xx: Add description for polling mode
Polling mode is enabled if the "interrupts" property is missing.
Thus, this commit deletes "interrupts" entry from "required" section
and adds a description for the fallback to polling mode at the
"interrupts" entry.

Pull tty / serial driver updates from Greg KH:
 "Here is the "big" set of tty/serial driver updates for 6.12-rc1.

  Nothing major in here, just nice forward progress in the slow cleanup
  of the serial apis, and lots of other driver updates and fixes.

  Included in here are:

   - serial api updates from Jiri to make things more uniform and sane

   - 8250_platform driver cleanups

   - samsung serial driver fixes and updates

   - qcom-geni serial driver fixes from Johan for the bizarre UART
     engine that that chip seems to have. Hopefully it's in a better
     state now, but hardware designers still seem to come up with more
     ways to make broken UARTS 40+ years after this all should have
     finished.

   - sc16is7xx driver updates

   - omap 8250 driver updates

   - 8250_bcm2835aux driver updates

   - a few new serial driver bindings added

   - other serial minor driver updates

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