[v5] Add Radxa CM5 module and IO board dts

[PATCH v5 2/3] arm64: dts: rockchip: Add rk3588 based Radxa CM5

Posted by Joseph Kogut 3 months, 3 weeks ago

Add initial support for the Radxa Compute Module 5 (CM5). The CM5 uses a
proprietary connector.

Specification:
- Rockchip RK3588
- Up to 32 GB LPDDR4X
- Up to 128 GB eMMC
- 1x HDMI TX up to 8k@60 hz
- 1x eDP TX up to 4k@60 hz
- Gigabit Ethernet PHY
