Hi Sachin, I must have missed this patch so better later than never ;). Please see my comments inline.

Since this bus is not physical, the reg property would not be anything more than purely an index. Also for consistency I'd use "regulator" as node name here, as this is what is used most commonly across all the dts files in arch/arm/boot/dts. So you could have then (in case of more than one regulator) regulators { compatible = "simple-bus"; #address-cells = <1>; #size-cells = <0>; mmc_reg: regulator@0 { /* ... */ reg = <0>; }; xxx_reg: regulator@1 { /* ... */ reg = <1>; }; /* ... */ }; Best regards, Tomasz -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
