/*
* vc4-kms-vga666-overlay.dts
* Configures a FenLogic or similar VGA666 DPI adapter when using the
* vc4-kms-v3d driver.
* If a suitable I2C level shifter is connected to GPIOs 0&1 and the VGA
* ID1/SDA (pin 12) and ID3/SCL (pin 15) lines, then there is the option to
* enable reading the EDID from the display.
