title: I2C; update DMAENGINE API to avoid deprecated functions
team: IO
key: 80032418-faad-11eb-80f4-3fc903436b31
assignee: Wolfram
status: Done
upstream:
- torvalds: a5f7cf953f2b47e5025a7acd1698eea997b2fd94 # i2c: rcar: update to new DMAENGINE API when terminating
- torvalds: 44df8a79283d94f4aed2e3a14ed67e49a3c210ca # i2c: sh_mobile: update to new DMAENGINE API when terminating
comments:
- "dmaengine_terminate_all() is deprecated and needs to be replaced"
- "because we set up DMA transfers in irq context, we need dmaengine_terminate_async() instead"
- "this needs synchronization code to avoid race conditions"
- "terminating DMA in irq context is superfluous, refactor driver"
- "same improvement can also be applied for SH Mobile I2C driver"
- "v1 sent"
- "merged"
