Please add the gpio-line-names from Eric's patch [1].

Thanks

[1] - https://patchwork.kernel.org/patch/9339857/


sorry i missed the fact that the same GPIO expander is on the CM3. So please move the exgpio node to bcm2837.dtsi and only define the gpio-line-names in this file.

The GPIO expander is not a part of the BCM2837 SoC, and not all BCM2837-based Pis have a GPIO expander - see the Pi 2+.
