This looks better to me now / more consistent with what we have in sc8280xp - where we do try to hit suspend and => retention/parking matters.
Parking the clock is separate from putting the system to sleep.

Yes but several of our clocks want to be parked, not switched off.. which obviously does matter in suspend.

IIUC we usually use shared ops on clocks that may have different users
(e.g. not only controlled by Linux) and/or that are crucial to the
functioning of hardware (like AXI clocks, which if gated would make
the system crash on any access attempt, from any subsystem, unless
turned on beforehand)

My question here for Sibi, is why sdcc2_apss_clk_src differs here from sc8280xp?

Is it wrong on sc8280xp or if correct sc8280xp then why is it not replicated here ?

Also @Sibi I realise alot of this code is autogenerated - it would be worthwhile finding/fixing the script that does the generation to plug in shared_ops instead of floor_ops if the input material has the necessary flags.
