Tidy up a bit the tree, by prefixing all include/dt-bindings/clock/ files
related to Ingenic SoCs with 'ingenic,'.

Merge tag 'tty-5.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty

2021-11-04T16:09:37+00:00

Pull tty / serial driver updates from Greg KH:
 "Here is the big set of tty and serial driver updates for 5.16-rc1.

  Nothing major in here at all, just lots of tiny serial and tty driver
  updates for various reported things, and some good cleanups. These
  include:

   - more good tty api cleanups from Jiri

   - stm32 serial driver updates

   - softlockup fix for non-preempt systems under high serial load

   - rpmsg serial driver update

   - 8250 drivers updates and fixes

   - n_gsm line discipline fixes and updates as people are finally
     starting to use it.

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

dt-bindings: serial: 8250_omap: allow serdev subnodes

2021-10-10T13:20:00+00:00

additionalProperties: false
ignores the pattern matching for serdev objects in serial.yaml, causing
error messages when serdev subnodes like bluetooth or gnss devices are
defined. Using unevaluatedProperties instead is the correct way
if arbitrary children nodes can appear.

dt-bindings: serial: fsl-linflexuart: add compatible for S32G2

2021-10-04T08:07:55+00:00

Add a compatible string for the uart binding of NXP S32G2 platforms. Here
we use "s32v234-linflexuart" as fallback since the current linflexuart
driver can still work on S32G2.

dt-bindings: serial: uartlite: Add properties for synthesis-time parameters

2021-09-14T08:05:32+00:00

The uartlite device is a "soft" device. Many parameters, such as baud
rate, data bits, and the presence of a parity bit are configured before
synthesis and may not be changed (or discovered) at runtime. However, we
must know what these settings are in order to properly calculate the
uart timeout (and to inform the user about the actual baud of the uart).

These properties are present for out-of-tree bindings generated by
Xilinx's tools. However, they are also (mostly) present in in-tree
bindings. I chose current-speed over xlnx,baudrate primarily because it
seemed to be used by more existing bindings. Although these properties
are marked as "required", note that only current-speed is required by
the driver itself. Hopefully, this will allow for an easier transition.
