Mainline U-Boot / kernel support for ROCK 3C

Hi.
Is mainline support for U-Boot planned for 3C ?
The same goes for 6.x kernel ?

Is DTS from 5.x line suitable for use with 6.x ?

ps. why there’s no subcategory for 3C ? :slight_smile:

You have to write a devicetree for 6.x mainline kernel.

As @amazingfate mention, someone first have to upstream a device tree for ROCK 3C to mainline linux.
After it has been accepted and merged into linux-rockchip maintainer tree, that device tree can then be used/imported to create a proper target in mainline U-Boot.

Fortunately the Quartz64-B schematics is very similar to ROCK 3C, I use this device tree for my mainline ROCK 3C needs :grinning:

Why Radxa can’t write proper dts file for their product?
