The kernel test robot is right as the ``&mipi_out`` node is missing a
closing ``;``, so thanks for that :-)
The problem is also present in v2, so I'll send a v3 shortly.

Luckily I've now found why my build script didn't catch it.

export PATH=~/dev/kernel.org/dt-schema-venv/bin/:$PATH CROSS_COMPILE=aarch64-linux-gnu- ARCH=arm64
make distclean
make debarm64_defconfig
make CHECK_DTBS=y W=1 rockchip/px30-cobra-ltk050h3146w-a2.dtb
<quite-a-long-list-of-all-boards-at-least-I-thought-so>

(debarm64_defconfig is my own defconfig based on Debian's kernel config)

That long list didn't have ``rockchip/rk3399-rockpro64-screen.dtbo``.
Is there a better/simpler way to validate all rockchip boards without
having to explicitly list each and every one of them?

make defconfig && make

or make dtbs

Best regards,
