The 7 lines driven by the TCA6507 can either drive LEDs or act as output-only GPIOs. To make this distinction in devicetree we use the "compatible" property. If the device attached to a line is "compatible" with "gpio", we treat it like a GPIO. If it is "compatible" with "led" (or if no "compatible" value is set) we treat it like an LED.
