Subject: [GIT PULL] slave-dmaengine update for 3.12
Hey Linus,
Back from the longish weekend here, so time to send you the pull request.
Okay we have fairly longish pull this time, and NO recent rebase which got you
annoyed last time :(
This pull brings:
- Andy's DW driver updates
- Guennadi's sh driver updates
- Pl08x driver fixes from Tomasz & Alban
- Improvements to mmp_pdma by Daniel
- TI EDMA fixes by Joel
- New drivers:
- Hisilicon k3dma driver
- Renesas rcar dma driver
- New API for publishing slave driver capablities
- Various fixes across the subsystem by Andy, Jingoo, Sachin etc...
