Other Parts Discussed in Thread: TPS650861, TPS549B22, TPS549D22, TPS546C20A, TPS546A24A, TPS546B24A, TPS546D24A
We are now estimating to implement DVFS on TPS40400.
There are some questions we would like to have clarification from TI before we start the implementation.
We know TI has provided DVFS compatible drivers for some PMIC like TPS650861.
Therefore we have the following questions:
- Does the TPS40400 driver released by TI compatible with DVFS in Linux kernel? (Does DVFS function work with TPS40400 driver?)
- Does TPS40400 have any interrupt function to notify ARM/CPU that the voltage change has been done?
- What is the time duration between TPS40400 gets I2C command to change the output voltage then TPS40400 really output target voltage accordingly?
