[RFC PATCH 0/6] arm64: dts: renesas: add SWDT

[Wolfram Sang <wsa+renesas@sang-engineering.com>]

I forgot over the years why we did not enable the SWDT on R-Car Gen3+.
The reason is that it is used by the firmware on Renesas boards.
However, this was not documented. So, based on a previous discussion
with Geert, here is an RFC how this documentation could look like:

* add the complete node to the SoC DTSI (here only R-Car H3, M3*)
* mark the node as "reserved" for the relevant boards
  (firmware should have done that(tm))

If this approach is acceptable, I'd handle the other SoCs, too, of
course. Looking forward to comments! Passes dtbs_check here BTW.
