Merge tag 'tty-6.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

2024-09-26T16:59:50+00:00

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"

dt-bindings: serial: add common properties schema for UART children

2024-08-19T22:04:55+00:00

Properties should be defined in only one place, thus add new
serial-peripheral-props.yaml schema with definition of common properties
for UART-connected devices (children of UART controller): current-speed
and max-speed.  The schema can be referenced by individual devices using
these properties.

dt-bindings: serial: add missing "additionalProperties" on child nodes

2024-08-19T22:04:55+00:00

All nodes need an explicit additionalProperties or unevaluatedProperties
unless a $ref has one that's false.  Add missing additionalProperties
for serial-attached devices.

dt-bindings: serial: Allow embedded-controller as child node

2024-08-19T11:39:02+00:00

There exist some embedded controllers (like Microsoft SAM found on
Surface devices or Apple Oscar found on old iPhones) that connect to
the host device via serial.

Allow that class of devices to exist under serial interface controller
nodes.
