I think we can drop the #if and #else...#endif so it's just the dm_regs table, as with bq27425.
I have fixed that and did take the chance to update my OpenPandora kernel so that I also could test and make the bq27500 working.
The biggest hurdle was to find out that I have to change the compatible string to "ti,bq27500-1" to get non-NULL dm_regs...

Does this look ok for
bat: battery { compatible = "simple-battery", "openpandora-battery"; voltage-min-design-microvolt = <3200000>; energy-full-design-microwatt-hours = <14800000>; charge-full-design-microamp-hours = <4000000>; };
?
I will send a patch for enabling both fuel gauges and the omap3-pandora-common.dtsi asap.
BR and thanks, Nikolaus
