Since the older implementation on i.MX6 uses 1.1V (HDMI_VP) and 2.5V (HDMI_VPH), I wonder whether each SoC should use their own name or whether there should be common names that don't include the voltage. I don't have the Synopsys HDMI TX docs, but I've seen avddhv and avddlv used of other cores' analog supplies. regards Philipp -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
