This matches the existing usage in DT, so
Reviewed-by: Geert Uytterhoeven <geert+renesas@glider.be>

However, I believe we do have a runtime issue here, as the driver
currently matches against dlg,da9062-watchdog only, so the watchdog
must be non-functional on DA9063?

Gr{oetje,eeting}s,

                        Geert

Of_compatible is defined in [1], but the corresponding driver[2] is missing the compatible
[1]
drivers/mfd/da9063-core.c:		.of_compatible	= "dlg,da9063-watchdog",

[2]
drivers/watchdog/da9063_wdt.c

Not sure of_compaible in MFD will instantiate driver [2] or not?

Cheers,
Biju
