The FRDM-i.MX8MP is an NXP development platform based on the i.MX8M Plus
SoC, featuring a quad Cortex-A53, Cortex-M7 co-processor, 4GB LPDDR4,
32GB eMMC, Wi-Fi 6/Bluetooth 5.4/802.15.4 tri-radio, Ethernet, HDMI/MIPI
display interfaces, camera connectors, and standard expansion headers.

Based on the device tree found in the NXP repository at github
https://github.com/nxp-imx-support/meta-imx-frdm and on imx8mp-evk
board kernel mainline device tree.

This is a basic device tree supporting:

 - Quad Cortex-A53
 - 4GB LPDDR4 DRAM
 - PCA9450C PMIC with regulators
 - Two NXP PCAL6416 GPIO expanders
 - RGB LEDs via GPIO expander
 - I2C1, I2C2, I2C3 controllers
 - UART2 (console) and UART3 (with RTS/CTS)
 - USDHC3 (8-bit eMMC)
 - SNVS power key (onboard power button)

There is never blank line between tags.

I assume you actually saw these SoBs in the code you took as your base?
Remember, do not add SoBs which were never present in the original work
(if company asks you, you can politely reply that they need to read what
SoB means)

That's anyway weirdly a lot of co-developed tags, are you sure they
wrote the code you took as the base here?

Best regards,
Krzysztof

Although I think you mentioned you wanted all these last time, so it's
fine. Although I did not think you will literally use that syntax and
literally all the tags from Daniel's responses, because the syntax was
not correct.
