No, the GPIO flags are ignored by gpiolib-of and the signal is active low. That's why there is that zero, no flags, and no enable-active-high property.
Yes, correct. The GPIO flag is ignored by "regulator-fixed". As you removed the 'enable-active-high' property, you turned the regulator to active low as needed. This is correct. gpio = <&gpio1 2 0> is the same as gpio = <&gpio1 2 GPIO_ACTIVE_HIGH> I just suggested gpio = <&gpio1 2 GPIO_ACTIVE_LOW> to make it clearer what is the real polarity. The GPIO flag is ignored, I know. No issues if you want to keep it as gpio = <&gpio1 2 0>. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
