There's an issue with adding the devicetree from the 5.16 kernel.

I get a compilation error due to a :missing .h in the devicetree files:

In file included from arch/arm/dts/imx8mq-librem5-r3.dtsi:11,
                  from arch/arm/dts/.imx8mq-librem5.dtb.pre.tmp:6:
arch/arm/dts/imx8mq-librem5.dtsi:13:10: fatal error: 
dt-bindings/rfkill/rfkill.h: No such file or directory
    13 | #include "dt-bindings/rfkill/rfkill.h"
       |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Should that get added to the u-boot source as well or should I modify 
the dts to remove this ?

For the kernel we also have 4 different dts files for the differences in 
PCB versions. For u-boot we don't need the differentiation as it deals 
with things like camera rotation and prox sensor sensitivity.

There's 2 ways to solve the this I think.

1) just use the latest librem5 dts file which is made up of 3 different 
dts(i) files.
2) have a defconfig for each of the different PCB versions.

Do you have a preference ?

Thanks
Angus
