If there is no difference between the OMAP3 and the OMAP4 WDT IP,
just add one entry "ti,omap3-wdt". And then in the OMAP4 DTS you will
just put : compatible = "ti,omap3-wdt"; or compatible =
"ti,omap4-wdt", "ti,omap3-wdt";
I'm still a little bit confused about the real need for the
"ti,omap4-wdt: entry, but it seems to be the way to do it in PPC.
I believe OMAP2, OMAP3 and OMAP4 share the same IP, so how about use
"ti, omap2-wdt"? and other dts files
put compatible like "ti,omap4-wdt", "ti,omap2-wdt" and "ti,omap4-wdt",
"ti,omap2-wdt".
Typo, should be "ti,omap3-wdt", "ti,omap2-wdt" and "ti,omap4-wdt",
"ti,omap2-wdt".

Xiao
