I guess you're not building the latest meta-freescale, since the latest version of
kernel recipes (linux-fslc and linux-fslc-imx) contains version v5.4.62. Or it is
possible that you're building linux-imx kernel, in which case you would have to
port the patch on top of your tree.

It seems that the repository has to merge the following patch:
https://lkml.org/lkml/2020/3/4/313

This is covered by [df35e878d0a51755fb500e2e8e29c7ebb0239756] which is
present in the kernel tree and came in with v5.4.56.

I guess you're not building the latest meta-freescale, since the latest version of
kernel recipes (linux-fslc and linux-fslc-imx) contains version v5.4.62. Or it is
