Subject: Removal of regulator-boot-on/always-on when a consumer exists

Hi Mark,

On the linux-arm-kernel list we are reviewing a patch from Michael (on
Cc), where he does:


       reg_3p3v: regulator-3p3v {
               compatible = "regulator-fixed";
               regulator-name = "3P3V";
               regulator-min-microvolt = <3300000>;
               regulator-max-microvolt = <3300000>;
               regulator-boot-on;
               regulator-always-on;
       };
};

&can1 {
       pinctrl-names = "default";
       pinctrl-0 = <&pinctrl_flexcan1>;
       xceiver-supply = <&reg_3p3v>;
};

My suggestion is to remove regulator-boot-on/regulator-always-on:

       reg_3p3v: regulator-3p3v {
               compatible = "regulator-fixed";
               regulator-name = "3P3V";
               regulator-min-microvolt = <3300000>;
               regulator-max-microvolt = <3300000>;
       };

,since reg_3p3v has can1 as its consumer.

Is my understanding correct?

Thanks,

Fabio Estevam
