H A D | am65-cpsw-nuss.c | fd23df72 Fri Nov 04 08:23:07 CDT 2022 Roger Quadros <rogerq@kernel.org> net: ethernet: ti: am65-cpsw: Add suspend/resume support
Add PM handlers for System suspend/resume.
As DMA driver doesn't yet support suspend/resume we free up the DMA channels at suspend and acquire and initialize them at resume.
Move the init/free dma calls to ndo_open/close() hooks so it is symmetric and easier to invoke from suspend/resume handler.
As CPTS looses contect during suspend/resume, invoke the necessary CPTS suspend/resume helpers.
