From: Chris Morgan <macromorgan@hotmail.com>

The Powkiddy X55 is a Rockchip RK3566 based handheld gaming device.
UART, ADC, eMMC, and SDMMC are tested to work in U-Boot and this
successfully boots mainline Linux.

Changes since V1:
 - Built on top of this patch series [1] which makes the ADC detect
   function more generic and also moves the board_rng_seed to a more
   generic location.
 - Updated U-Boot specific devicetree to drop redundant values and
   add nodes required for ADC detection in SPL.
 - Updated defconfig to add additional options for SPL ADC detection
   logic as well as drop some drivers that are not needed. Note that
   CONFIG_DM_PMIC_FAN53555 is used by the tcs,tcs4525 regulator on
   i2c0 at 0x1c. Additionally the code fails to compile without
   selecting CONFIG_SPL_ROCKCHIP_BACK_TO_BROM.

+U-Boot for Powkiddy X55 Handheld Gaming Console
+===============================================
+
+This allows U-Boot to boot the Powkiddy X55 handheld gaming console.
+The X55 is very similar to the other existing Powkiddy RK3566 based
+devices, except that ADC channels 0-3 are used for the ADC joysticks.
+As a result the same auto detection functionality cannot be used on
+this device as the others.
+
+The indicator LED will change color based on the boot stage. Red means
+the device is powered on but has yet to start U-Boot, amber means the
+device has started U-Boot and is waiting to boot Linux, and when Linux
+has taken over the LED should change to green (or however it has been
+configured by the user).
+
+In the event the device needs to enter Rockchip download mode, a user
+can, starting with the power off, hold the left joystick all the way
+to the left and then power on the device. At this point the USB-C port
+marked DC/OTG should be set to peripheral mode and allow a user to
+manipulate the device with the rkdeveloptool tool.
+
+See :doc:`../rockchip/devicetree/rockchip` for building and flashing
+instructions.
