i3c: dw: Add support for power management

[PATCH 0/3] i3c: dw: Add support for power management

Posted by Aniket 1 year, 7 months ago

These patches add pm support for the dw i3c controller.
Controller registers that can be lost are saved and restored during resume.
Clocks, resets and pads are put in their relevant state during suspend and resume.
For runtime pm, power is resumed and later suspended for the xfer/IBI APIs.
