Following tests (1 &2) were performed:
1. make -j32. Build the images and DTB to test the functionality.
2. make dt_binding_check DT_SCHEMA_FILES=freescale.
3. make CHECK_DTBS=y freescale/imx8ulp-evk.dtb
Before sending the V4 patch for review, I have ran tests 1 &2. Both were passing.
But after seeing the page shared by you, ran the 3rd test and I was able to reproduce the issue, you might be referring to.
For V5, I will perform all the 3 tests.
