   4 Subject: [PATCH] arm64: dts: rockchip: Add Radxa ROCK 4D device tree
   5
   6 The Radxa ROCK 4D board is based on the Rockchip rk3576 SoC.
   7
   8 The device tree adds support for basic devices:
   9  - UART
  10  - SD Card
  11  - Ethernet
  12  - USB
  13  - RTC
  14
  15 It has 4 USB ports but only 3 are usable as the top left one is used
  16 for maskrom.
  17
  18 It has a USB-C port that is only used for powering the board.
