Subject: [PATCH v5 00/61] dmaengine: Implement generic slave capabilities retrieval
Hi,
As we discussed a couple of weeks ago, this is the third attempt at
creating a generic behaviour for slave capabilities retrieval so that
generic layers using dmaengine can actually rely on that.
That has been done mostly through two steps: by moving out the
sub-commands of the device_control callback, so that the dmaengine
core can then infer from that wether a sub-command is implemented, and
then by moving the slave properties, such as the supported buswidth,
to the structure dma_device itself.
Comments are as usual appreciated!
Thanks,
Maxime
Changes from v4:
- Rebased on top of current dma/next
- Converted AT91 XDMAC driver to the new API
- Updated the documentation to reflect our changes
Changes from v3:
- Removed the generic_slave_caps flag
- Merged the patch introducing a generic slave caps functions with
the one introducing the dma_device capabilities
Changes from v2:
- Reworked dma_chan_get/dma_chan_put in order to optionally use
device_alloc_chan_resources/device_free_chan_resources
- Modified a few client drivers that were still calling
device_control directly to use the dmaengine API instead
- Totally remove device_control and device_slave_config
- Move device_control BUG_ON removal earlier in the patch set to
avoid breaking the bisectability
- Converted rapidio tsi721 driver too.
- Minor cosmetics changes and fixes suggested by Laurent Pinchart
and Andy Shevchenko
- Fixed a few build warnings
- Collected the various Acked-by
- Rebased on top of 3.18-rc1
Changes from v1:
- Add a flag to trigger the generic slave caps mechanism
- Add a warning whenever this flag is not set, or when a
device_control callback is still defined
- Migrate all existing users to use the new callbacks, and the
generic slave capabilities
