[PATCH 0/2] arm64: dts: rockchip: Add Radxa E54C

[Chukun Pan]

This series requires the following commit in Linux v7.2 to make the
switch work: https://github.com/torvalds/linux/commit/9da2c8672f77

There was a conflict between eMMC and SPI Flash, so the unmounted
eMMC was disabled. The schematic can be found below:
https://dl.radxa.com/e/e54c/hw/radxa_e54c_v1.2_schematic.pdf

The following functions were tested:
- Boot from SD card using generic-rk3588 u-boot
- USB Type-C connection to RTL8153 network card
- USB Type-C connection to USB 3.0 drive
- 2x USB 2.0 and 1x USB 3.0 Type-A HOST
- RTL8367RB 4-Port Gigabit Switch
- HDMI 1080P Output
- Button and LED
- PCIe NVMe SSD
