+### rk3318-box-led-conf3
+
+This device tree overlay is suitable for MXQ-RK3328-D4_A board which
+has an integrated PMIC (RK805). The dtbo is very important to achieve
+1.3 Ghz speed for CPU and stable voltages for other parts of the
+system. Also enables gpio leds and keys.

 ### rk3318-box-emmc-ddr

 Activates eMMC DDR capability for rk3318 tv box boards. Probably all the eMMC chips
