Yours: + ldo8-in-supply = <&tps65090_dcdc3_reg>; + ldo9-in-supply = <&palmas_smps9_reg>; Ours: ldo8-in-supply = <&tps65090_dcdc2_reg>; ldo9-in-supply = <&tps65090_dcdc2_reg>; We also specify supplies (floating) for smps6 and smps10. I don't think that matters though. Also we have the vmmc-supply and sd-slot-supply propeties set for the sd card slot, like so: vmmc-supply = <&palmas_smps3_reg>; sd-slot-supply = <&palmas_smps9_reg>; Also, we have the interrupt trigger mode different for the palmas: Yours: + interrupts = <0 86 0x4>; Ours: interrupts = <0 86 0x8>; I think other than that they should be the same. -Rhyland -- nvpublic
