@0 and @1 are used for "usb_otg_vbus" and "usb_h1_vbus" regulators in 
dts for phyFLEX module (imx6qdl-phytec-pfla02.dtsi) which gets included 
before base board dts (imx6qdl-phytec-pbab01.dtsi)

why is there no need for 'regulator-alweys-on'? I see it in
similar fixed regulator descriptions in imx6qdl-sabrelite.dtsi,
imx6qdl-wandboard.dtsi, imx6qdl-nitrogen6x.dtsi and many other
boards.

yes, thanks. It is present in Documentation but now I see that it
was actually removed not that long ago. I will remove this
property with next patchset.
