I now that this patch is being reworked, but please note that the
following warnings that I reported are seen also with this patch:
[ 9.119117] arm-scmi firmware:scmi: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16
[ 9.129146] arm-scmi firmware:scmi: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16
[ 9.160328] arm-scmi firmware:scmi: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16
[ 9.175229] arm-scmi firmware:scmi: Failed to add opps_by_lvl at 3417600 for NCC - ret:-16
which seems to suggest that the approach taken by this patch is not
necessarily the right one.
Can you please also comment on why this is an issue on x1e80100 in the
commit message?
Johan
