+This document describes overlays provided in the kernel packages
+For generic Armbian overlays documentation please see
+https://docs.armbian.com/User-Guide_Allwinner_overlays/
+
+### Platform:
+
+rk322x (Rockchip)
+
+### Provided overlays:
+
+- rk322x-cpu-hs
+- rk322x-cpu-stability
+- rk322x-emmc*
+- rk322x-nand
+- rk322x-emmc-nand

+- rk322x-usb-otg-peripheral
+
+### Overlay details:
+
+### rk322x-cpu-hs
+
+Activates higher CPU speed (up to 1.4ghz) for rk3228b/rk3229 boxes
+
+### rk322x-cpu-stability
+
+Increases the voltage of the lowest operating point to increase stability
+on some boards which have power regulation issues. Also adds a settling
+time to allow power regulator stabilize voltage.
+
+### emmc*
+
+rk322x-emmc activates onboard emmc device node and deactivates the
+nand controller.
+rk322x-emmc-pins sets the pin controller default pull up/down
+configuration, not all boards are happy with this overlay, so your
+mileage may vary and may want to not use it.
+rk322x-emmc-ddr-ph45/ph180 sets the emmc ddr mode. First overlay
+sets the default phase clock shifting to 45 degrees, the second
+overlay to 180 degrees. They are alternative, choose the one that
+makes your emmc perform better.
+rk322x-emmc-hs200 enables the hs200 mode. It is preferable to
+ddr mode because it is more stable, but old emmc parts don't
+support it.
+
+### nand
+
+Activates onboard nand device node and deactivates the emmc controller.
+Also sets up the pin controller default pull up/down configuration
+
+### 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)
+led-conf1 is commonly found in boards made by Chiptrip manufacturer
+led-conf2 is found in other boards with R329Q and MXQ_RK3229 marking
+led-conf3 is found in boards with R28-MXQ marking
+led-conf4 is found on boards with T066 marking
+led-conf5 is found on boards with IPB900 marking from AEMS PVT
+led-conf6 is found on boards with MXQ_PRO_V72 and similar markings, possibly
+with eMCP module.
+led-conf7 is found on boards with R29_MXQ marking
+
+### rk322x-alt-wiring
+
+Some boards have different SDIO wiring setup for wifi chips. This overlay
+enables the different pin controller wiring and power enable
+
+### rk322x-ddr3-*
+
+Enable DRAM memory controller and sets the speed to the given speed bin.
+The DRAM memory controller reclocking only works with DDR3/LPDDR3, if
+you enable one of these overlays on boards with DDR2 memory the system
+will not boot anymore
+
+### rk322x-bt-*
+
+Overlays that enable bluetooth devices. Most common bluetooth chips are
+realtek ones.
+rk322x-bt-8723cs: enable this overlay for 8723cs and 8703bs wifi/bluetooth
+
+### rk322x-usb-otg-peripheral
+
+Set the OTG USB port to peripheral mode to be used as USB slave instead
+of USB host
