I would reword this to: "If any of these properties is absent then the corresponding setting will be untouched" > +- strict-supply-voltage: <1|0> Set/Reset STRICT flag in CONFIG1 This is too less info on the strict bit: You can perhaps add some more description from data sheet. The Supply Voltage supervisor has two modes of operation, controlled by the STRICT bit. With the STRICT bit set to 0, all enabled rails of the five regulators are monitored for undervoltage only with relaxed thresholds and deglitch times. With the STRCT bit set to 1, all enabled rails of the five regulators are monitored for undervoltage and overvoltage with tight limits and short deglitch times. > +- under-voltage-limit: Select 2.75, 2.95, 3.25 or 3.35V as UVLO in CONFIG1 Again some more description on uvlo please. > +- under-voltage-hysteresis: Select 200mV or 400mV UVLOHYS in CONFIG2 Even here for hysteresis. > + > Example: > tps65218: tps65218@24 { > reg = <0x24>; > compatible = "ti,tps65218"; > interrupts = <GIC_SPI 7 IRQ_TYPE_NONE>; /* NMIn */ > interrupt-controller; > + strict-supply-voltage = <1>; > + under-voltage-hysteresis = <400000>; > + under-voltage-limit = <3350000>; > + > #interrupt-cells = <2>; > > dcdc1: regulator-dcdc1 { >
