[PATCH 4/5] arm64: dts: rockchip: add Rock 5B+

Sebastian Reichel
2025-03-24T17:04:24Z

Add ROCK 5B+, which is an improved version of the ROCK 5B with the
following changes:

* Memory LPDDR4X -> LPDDR5
* HDMI input connector size
* eMMC socket -> onboard
* M.2 E-Key is replaced by onboard RTL8852BE WLAN/BT
* M.2 M-Key 1x4 lanes is replaced by 2x2 lanes
* Added M.2 B-Key for USB connected WWAN modules (untested)
* Add second camera port (not yet supported in upstream Linux)
* Add dedicated USB-C port for device power (no impact in DT;
the existing port has not been changed and the new port is
handled by CH224D standalone chip)
