| + | The SoCs have been designed with the RTL8231 LED expanders in mind as a first-class citizen. A hardware peripheral is present that can keep track of the state of one (or two on RTL93xx) RTL8231 chip(s). The SoC's have dedicated pins and controllers for this task. For rtl930x C1 `LED_MDC` and C2 `LED_MDIO` For rtl931x, AL18 `LED_MDC` and AK18 `LED_MDIO`. This does require the RTL8231 connected to only function as a LED expander. This should not be confused with the dedicated `EXT_GPIO_MDxx` pins! | ||
