Shouldn't some rpm ids be changed like they were for msm8916 in the following patch ?
c497f9322af9 ("interconnect: qcom: msm8916: Remove rpm-ids from non-RPM nodes")
https://patchwork.kernel.org/project/linux-arm-msm/patch/20201112105140.10092-1-georgi.djakov@xxxxxxxxxx/
Maybe they should. I don't have the hardware to try it, but the test will be
to just add the NoC DT nodes, enable the driver and inspect the boot log for
messages like:
[ 2.926647] qcom_icc_rpm_smd_send mas X error -6
Thanks,

Hi Vincent & Georgi,
Thanks, I ran your suggestion on an MSM8939 board (with an additional
change to print slave IDs as well). Results:
[ 1.901376] qcom_icc_rpm_smd_send slv 24 error -6
[ 2.005977] qcom_icc_rpm_smd_send mas 20 error -6
[ 2.010250] qcom_icc_rpm_smd_send slv 20 error -6
[ 2.014684] qcom_icc_rpm_smd_send slv 106 error -6
[ 2.019338] qcom_icc_rpm_smd_send slv 107 error -6
[ 2.024615] qcom_icc_rpm_smd_send slv 29 error -6
[ 2.028782] qcom_icc_rpm_smd_send mas 3 error -6
[ 2.034657] qcom_icc_rpm_smd_send mas 100 error -6
(and there's another slv 131 that's hidden by the mas 100 failure)
Jun, I'll send you the patch I tested with to silence all these errors,
if you want to just squash that into the next version of your patchset.
Thank you for doing this! Please send a follow-up patch as i already
queued Jun's patches.
Thanks,
Georgi
