Typically the pinctrl properties are part of the device node that uses them. For the other boards, that's not possible, as they are shared by all PMIC nodes. Hence the other boards are the exceptions, actually ;-) Note that for multi-PMIC boards, adding the pinctrl properties to a single PMIC node won't work, as that would break: 1. The case where the driver for that PMIC is not compiled in, 2. The R-Car Gen2 regulator quirk. Gr{oetje,eeting}s, Geert

Well it wouldn't work because it's shared by two PMICs and thus two driver instances in the first place.
