Given you are testing whether it is on > or off to report LED state it feels to me it might be a GPIO pin, not > regulator... In this case it's a real regulator, not a GPIO. But even if it was a GPIO, I still could use gpio-regulator[*] which handles gpio using the regulator framework. In this case, depending on how the leds are enabled on the DTS, in the driver I would use only one api (regulators indeed) for both the cases.
