Not sure if this solve the -84 write error when using ath10k that
Kevin reported.

Thanks for the suggestion and adding me. I have not had much time to work on this lately but I did dig into this patch a bit today.

This patch has no impact in my situation for a couple reasons:

1. I verified my boot loader is not changing the defaults (at least on the interface used for WiFi, it is changing them for eMMC interface).

2. The mainline imx8mm.dtsi file defines fsl,tuning-start-tap and fsl,tuning-step in which case I do not think this patch makes any difference as the code was already masking the bits in question in that case.
