Half the time this is spelled "i.MX..." and half the time it's
"iMX..." Pick one and use it consistently. I think "i.MX..." is
right because that's what I see on nxp.com, e.g.,
https://www.nxp.com/products/processors-and-microcontrollers/arm-processors/i-mx-applications-processors/i-mx-8-processors/i-mx-8-family-arm-cortex-a53-cortex-a72-virtualization-vision-3d-graphics-4k-video:i.MX8
Also applies to several subsequent patches.
