There is a newer version of this series
[PATCH 2/4] arm64: dts: imx: Add imx8mp-iota2-lumpy board
Posted by Michal Vokáč 2 months, 1 week ago 
The IOTA2 Lumpy board is based on the i.MX8MPlus EVK.

Basic features are:
- 4GB LPDDR4
- 64GB eMMC
- 2x 1GB Ethernet
- USB 3.0 Type-C dual role port, without power delivery
- USB 3.0 Type-A host port
- RGB LED - PWM driven
- speaker - PWM driven
- RTC with super capacitor backup

Suggest you try tools https://github.com/lznuaa/dt-format
to make sure nodes sorted.

Any issue let me know.

I will try it for v2.
Thanks a lot.

^^^ The pwm-gpios property should not be here. I will remove it in v2.
