If you have something in omap4-panda-common.dtsi and the same entry in the omap4-panda-es.dts, the entries in omap4-panda-es.dts will override and append the entries in omap4-panda-common.dtsi. So I think you can avoid the empty entry that way.

Can we cleanly append to omap4_pmx_core without overriding the whole node? I don't want to recreate the pmx_core node in the es file. Dan

Yes that should work just fine.

The GPIO for LED D1 on the omap4-panda a1-a3 rev and the omap4-panda-es are different. A1-A3 = gpio_wk7 ES = gpio_110 There is no change to LED D2 Abstract away the pinmux and the LED definitions for the two boards into the respective DTS files.
