This is incorrect. iva2_ck is not an interface clock. Since it cannot auto-idle, specifying it here prevents the IVA and at least one of the CORE clockdomains from going idle, which causes PM problems such as these upon system suspend: [ 70.626129] Powerdomain (iva2_pwrdm) didn't enter target state 1 [ 70.626190] Powerdomain (core_pwrdm) didn't enter target state 1 Fix by specifying the actual interface clock in the hwmod data.
