What's going on here? A gap in the selectors? If that's the case you probably want to be using linear ranges.
Yes device does not want to be configure the vsel to 0x25 to 0x3F 01h-24h : V_LDO1=0.8V+ldo1_vsel*25mV 25h-3Fh : do not use 40h-7Fh : V_LDO1=1.725V+(ldo1_vsel-40h)*25mV Let me use linear range.

When the rail is configured externally controlled then we are not providing the enable/disable callback to enable through register access. So core will not be able to enable it.
Here, we are making sure that it is enabled through register write. After that enable/disable can be done by device-input pin toggeling. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
