It does not look like you tested the DTS against bindings. Please run
`make dtbs_check W=1` (see
Documentation/devicetree/bindings/writing-schema.rst or
https://www.linaro.org/blog/tips-and-tricks-for-validating-devicetree-sources-with-the-devicetree-schema/
for instructions).

The node names are clearly wrong and you got output. It's easy to spot
if your patch worked in the first place:

fatal error: dt-bindings/watchdog/aspeed-wdt.h: No such file or directory


The patch series was based on Linus's tree at the time I sent it; that file was added in commit 9931be2cfca3 ("dt-bindings: watchdog: aspeed-wdt: Add aspeed,reset-mask property"), which was included in the 6.7-rc1 tag, FWIW.

After some debugging I discovered that the reason I wasn't getting any output from dtbs_check was that I had neglected to specify ARCH=arm when invoking it, and when that defaulted to x86 it silently did a whole bunch of nothing. It might be nice if something emitted some sort of warning when invoked with nonsensical parameters (especially if I've explicitly specified a dtstree=... argument pointing to arch/arm/...), but oh well.

After re-running it with ARCH=arm, it produced a fairly voluminous spew of output, though after combing through it all as best I can tell only one or two lines of it actually pertain to the .dts in question itself (the vast majority being from a .dtsi it #includes). I've fixed the one remaining issue it reported (missing #address-cells and #size-cells on the FRU eeprom node) and will post a v2 in the next few days (and likewise on the spc621d8hm3 series).
