21203e098c dt-bindings: i3c: Add AST2600 i3c controller
Add a devicetree binding for the ast2600 i3c controller hardware. This
is heavily based on the designware i3c core, plus a reset facility
and two platform-specific properties:

 - sda-pullup-ohms: to specify the value of the configurable pullup
   resistors on the SDA line

 - aspeed,global-regs: to reference the (ast2600-specific) i3c global
   register block, and the device index to use within it.

28ffe8bf90 dt-bindings: Clean-up undocumented compatible strings
Adding checks for undocumented compatible strings reveals a bunch of
warnings in the DT binding examples. Fix the cases which are typos, just
a mismatch between the schema and the example, or aren't documented at all.
In a couple of cases, fixing the compatible revealed some schema errors
which are fixed.

There's a bunch of others remaining after this which have bindings, but
those aren't converted to schema yet.

Silvaco provide a dual-role I3C master.

Description is rather simple: it needs a register mapping, three
clocks and an interrupt.

de67276e66 dt-bindings: i3c: mipi-hci: Include the bus binding
Update a little bit the content to match the bus binding, including:
- the node title should have been named after the description done
  in the historical i3c.txt file, ie: i3c-master@<address>
- child nodes should be accepted even though the drivers do not currently
  support it
- #address-cells and #size-cells are also mandatory and have specific
  values

c307912d28 dt-bindings: i3c: MIPI I3C Host Controller Interface
The MIPI I3C HCI (Host Controller Interface) specification defines
a common software driver interface to support compliant MIPI I3C
host controller hardware implementations from multiple vendors.

All that is needed is an I/O area and an interrupt signal;. The hardware
is self-advertising wrt its implementor and implemented capabilities so
there is currently no details that the driver can't figure out on its own.
