No need to pass bootargs here.

Building with W=1 should give a dtc warning due to the unit address
and reg mismatch.

Unneeded blank line.

No need for this imxrt1050-evk container.

Put it on a single line. It helps readability. Same applies globally.

Make 'status' to be the last property. Remove the blank line.

Please group more elements into the same line.
Putting one entry per line makes it extremely long.

Put the interrupts into a single line.
