OK yeah clock-controller sounds good to me.
Below is this one updated to use clock-controller naming.

I've tested that the interconnect target module enables and idles just fine when probed with ti-sysc with PM runtime control via sys:
# echo on > $(find /sys -name control | grep /5600)
Patch has arrived in v5.4-rc1 but does not work in that environment for me:
root@letux:~# echo on > $(find /sys -name control | grep /5600) [ 213.490926] clock-controller:clk:0000:0: failed to enable root@letux:~# uname -a Linux letux 5.4.0-rc1+ #1083 SMP Sat Oct 5 17:47:13 CEST 2019 armv7l GNU/Linux root@letux:~# find /sys -name control | grep /5600 /sys/devices/platform/44000000.ocp/5600fe00.target-module/power/control root@letux:~#
I have tested our own tree but also mainline (plus some minimal patch set to run the Pyra) using omap2plus_defconfig.
Does it work on omap5uevm?
Is there some related patch needed that did not yet arrive in v5.4-rc1?
BR and thanks, Nikolaus
