Hi,
Referring to the list of clock identifiers in the link and also refer the clock summary taken from /sys/kernel/debug/clk
https://software-dl.ti.com/tisci/esd/latest/5_soc_doc/am62x/clocks.html
Clk_summary does not lis all the Clock IDS. Could you please, let us know how to get the clock frequency corresponding to the device IDs AM62X_DEV_DDR16SS0 (ID = 170)
AM62X_DEV_MMCSD0 (ID = 57) ?
Regards,
Prabhu

Clock tree summary taken from /sys/kernel/debug/clk
You should be able to dump all the clocks using k3conf like this:
k3conf dump clock <deviceid>
/sys/kernel/debug/clk only shows the clocks that are actively configured in the device tree.

Bas Vermeulen
Thanks Bas.
Yes Prabhu, k3conf utility packaged in the SDK can dump all the clocks.

Suren
