Hi Daniel,

Right, but NXP makes a total mess with authorship.

Please see this version from February that states the original author
as Xiaofeng Wei <xiaofeng.wei@xxxxxxx>:

https://github.com/nxp-imx-support/meta-imx-frdm/blob/lf-6.6.36-2.1.0/meta-imx-bsp/recipes-kernel/linux/linux-imx/0023-arm64-dts-Add-i.MX8MP-FRDM-board-support.patch

Then this one from July states the original author as Joseph Guo
<qijian.guo@xxxxxxx> and it also has:

Signed-off-by: Steven Yang <steven.yang@xxxxxxx>
Signed-off-by: Lei Xu <lei.xu@xxxxxxx>

https://github.com/nxp-imx/linux-imx/commit/fd8010b46bb00344fa519c73b643fad71da5887b

How are we supposed to know the correct authorship tags from the NXP
commit, then?

Rogerio's changes are significant as the dt-schema passes now.

The NXP commit has all the dt-schema warnings found in downstream BSPs.

For example, it makes the old mistake of describing:

 spidev1: spi@0 {
   reg = <0>;
    compatible = "lwn,bk4";
    spi-max-frequency = <1000000>;
 };

Which is totally wrong.
