Hi Tim,

commit description is nice (and required), can you add it next time? No need
for v2, I'll add something myself to all your patches this time.

BTW it's quite helpful to include the upstream kernel version used for the
backport and include it in the patch filename, for example:

 005-v5.7-ARM-dts-imx6qdl-gw553x-add-lsm9ds1-iio-imu-magn-supp.patch

Cheers,

Petr

Petr,

Ok - will make sure I add that in the future. This particular one just
recently got accepted and I'm not sure if it will be pulled into a
later 5.6-rc or will land in 5.7 (likely the latter).
