[v2,1/3] dt-bindings: watchdog: modify description for mt2712 and mt8183

[Crystal Guo]

Besides watchdog, mt2712 and mt8183 also provide sub-system software
reset features. But mt6589 not support this feature.

[v3,3/3] watchdog: mtk_wdt: merge all the reset numbers in one head file

[Crystal Guo]

mt8xxx-resets.h actually just used to define TOPRGU_SW_RST_NUM.
Instead of resubmit a new mt8xxx-reset.h for a new IC, merge all
the reset numbers in one head file.

Maybe I didn't explain myself properly. We want to have all resets in one file 
and do not want to have the resets for the watchdog in a different file. That 
means I don't thin your patch is correct and the effort should be abandoned.

Matthias

Do you mean to keep the current way unchanged? For example, with a new
SOC 8192, should add a new head file mt8192_resets.h for the resets
numbers.
