[PATCH 0/3] arm64: dts: rockchip: Add Radxa E24C

[Jonas Karlman <jonas@kwiboo.se>]

This series adds dt-bindings and initial device tree for the Radxa E24C.

The product page for E24C mentions that onboard eMMC is optional and the
model I have come with SPI flash instead of eMMC.

On RK3528 the eMMC and SPI flash is muxed so only one of them can work.

I have included both SPI flash and eMMC nodes in the device tree,
however the sdhci node has been marked with status=fail. Something that
possible could be enabled using a DTBO or FDT fixup by the bootloader.

This also leaves out describing the RTL8367RB-VB switch as support for
the switch requires dt-binding and/or driver changes to make it work,
something that will be handled in a separate follow-up series.

This board can be booted from SD-card using the U-Boot 2025.07
generic-rk3528 target or preferably using work-in-progress patches [1].

This series depends on following series for a clean apply:
- arm64: dts: rockchip: Add ROCK 2A/2F, Sige1 and NanoPi Zero2 [2]
- rockchip: Add power controller support for RK3528 [3]
- rockchip: Add USB 2.0 support for RK3528 [4]

A branch with all these (and some more) patches can be found at [5].
