hm... modulemode SWCTRL causes wait_target_ready to fail. Any hints ?
gets stuck in transition state. PRCM_CM_WKUP_DBGSS_CLKCTRL is always
read as 0x 12510f00 which would translate into:

- module disabled
- all opt clocks are on
- module is transitioning
- module in standby
- clkA as TPIU and STM trace clock
- all dividers set to 2
just fyi, checking with HW folks, this might be a new bug, unless
debugss needs something special.
If that happens on DEBUGSS disable, it's probably the same issue as on 
AM33xx:

Does adding HWMOD_INIT_NO_IDLE fix the issue you're seeing?
I'll try it out in a bit...
