On i.MX6 the HDMI_VP (1.1 V) and HDMI_VPH (2.5 V) are usually supplied by the internal LDO_SoC via VDD_SOC_CAP (also used for ARM cache, SATA, and PCIe) and the LDO_2P5 via VDDHIGH_CAP (also used for PLLs, MIPI, SATA, PCIe, USB, and LVDS), respectively. While I haven't seen anyone ever do this, it should be possible to supply them from an external regulator. 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
