Have you checked this is the case both in dm814x and dm816x TRM?
Also the documentation may not be complete FYI, might be also
worth checking the legacy TI kernel tree to be sure.

Tony

In DM814x TRM, the CM_ALWON_L3_SLOW_CLKSTCTRL does not have IDLEST field.
Same in DM816x TRM.

In this particular case, the IDLEST is handled in the MDIO hwmod.

I'll check the TI tree to be sure...

Tony,

In TI's tree, there is no L3_MED hwmod but the L3_SLOW hwmod has NO_IDLEST flag.

Is there any other issue about this patchset ?

Thanks for checking. Well one thing, if this is needed as fix, then a
description of what happens without it would be good to have.
