i2c: qup: Allow scaling power domains and interconnect

[PATCH 0/3] i2c: qup: Allow scaling power domains and interconnect

Posted by Stephan Gerhold 2 years ago

Make it possible to scale performance states of the power domain and
interconnect of the I2C QUP controller.

This is necessary to guarantee performance with power management
enabled. Otherwise these resources might run at minimal performance
state which is not sufficient for certain workloads.
