+
+### Platform:
+
+rk322x (Rockchip)
+
+### Provided overlays:
+
+- rk322x-cpu-hs
+- rk322x-emmc
+- rk322x-nand
+- rk322x-emmc-nand
+- rk322x-led1-low
+- rk322x-led1-high
+- rk322x-led2-low
+- rk322x-led2-high
+
+### Overlay details:
+
+### rk322x-cpu-hs
+
+Activates higher CPU speed (up to 1.4ghz) for rk3228b/rk3229 boxes
+
+### emmc
+
+Activates onboard emmc device node and deactivates the nand controller.
+Also sets up the pin controller default pull up/down configuration
+
+### nand
+
+Activates onboard nand device node and deactivates the emmc controller.
+Also sets up the pin controller default pull up/down configuration
+
+### emmc-nand
+
+Activates onboard nand and emmc devices. Usually they are alternative
+because manufacturers share the same pads so emmc and nand cannot be
+mixed together. Usually this works because the emmc and nand drivers
+can automatically guess what's in the pads, but may bring instabilities
+or misdetections. Also does not set up the pin controller default
+configuration, which in turn can be detrimental of stability and
+performance
+
+### rk322x-led-conf*
+
+Each device tree of this kind provides a different known wiring configuration
+(ie: gpio and active low/high) of the onboard leds. Each board manufacturer
+usually choose a different GPIO for the auxiliary led, but the main "working"
+led is always wired to the same gpio (although it may be active high or low)
