Thanks for this info.
I see that MCPM, TC2_PM & SPC configuration needs to be enabled to have
TC2 power management. However MCPM also depends on CCI configuration
to register smps ops.
In my config, I dont have CCI config enabled

Can you please suggest right configuration to be enabled and also dts
configuration
for SPC, CCI to enable TC2 power mgmt.

Also I am using u-boot. Do I need to use UEFI/firmware to enable TC2 power mgmt?
I remember, some time back, I have tried linaro tracking git and
failed to boot my board
