From: Quentin Schulz <quentin.schulz@xxxxxxxxx>
The Haikou carrierboard has an EEPROM on LVDS_BLC_CLK/DAT which are
signals that can carry either I2C or be used as HPD for eDP0/1.
Only eDP0 is routed from RK3399 Puma SoM but only exposed on Haikou
through the Video Connector, a fake PCIe connector. So to be able to use
eDP one would need to use a Device Tree overlay. Therefore, let's
default to having an EEPROM in Haikou carrierboard DTS.
