We have a regulator for it already in ulcb.dtsi. Use it instead. Signed-off-by: Wolfram Sang Reviewed-by: Geert Uytterhoeven --- Following a suggestion from Geert[1], let's inherit the 3.3V regulator from ulcb.dtsi. I kept the other KF regulators because: - 'hdmi_1v8' is really derived from d3.3v on the KingFisher board. It is named "T1.8V" in the schematics. Maybe we rename it? - 'snd_vcc5v' looks like D5V to me. While it seems available on the connectors, it looks unused on the ULCB. So, keep it KingFisher only. But maybe rename it to "reg_5v"?
