     4/8/16GB memory LPDDR4x
     Mali G610MC4 GPU
     MIPI CSI 2 multiple lanes connector
     4-lane MIPI DSI connector
     Audio – 3.5mm earphone jack
     eMMC module connector
     uSD slot (up to 128GB)
     2x USB 2.0, 2x USB 3.0
     2x micro HDMI 2.1 ports, one up to 8Kp60, the other up to 4Kp60
     Gigabit Ethernet RJ45 with optional PoE support
     40-pin IO header including UART, SPI, I2C and 5V DC power in
     USB PD over USB Type-C
     Size: 85mm x 56mm (Raspberry Pi 4 form factor)

Changes in v4:
- tweaked the defconfig as reviewed by Jonas
- moved some of bootph-all to rk3588s-u-boot.dtsi
- renamed fdt fixup function
Changes in v3:
- forgot to add defconfig and include file, added now, sorry
Changes in v2:
-fixed wrong Kconfig text (rk3588s instead of rk3588)
-changed doc name (rk3588s instead of rk3588)
