[PATCH v3 0/3] Unified fwnode endpoint parser

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




Hi folks,

We have a large influx of new, unmerged, drivers that are now parsing
fwnode endpoints and each one of them is doing this a little bit
differently. The needs are still exactly the same for the graph data
structure is device independent. This is still a non-trivial task and the
majority of the driver implementations are buggy, just buggy in different
ways.

Facilitate parsing endpoints by adding a convenience function for parsing
the endpoints, and make the omap3isp driver use it as an example.

I plan to include the first patch to a pull request soonish, the second
could go in with the first user.

since v2:

- Rebase on CCP2 support patches.

- Prepend a patch cleaning up omap3isp driver a little.

since v1:

- The first patch has been merged (it was a bugfix).

- In anticipation that the parsing can take place over several iterations,
  take the existing number of async sub-devices into account when
  re-allocating an array of async sub-devices.

- Rework the first patch to better anticipate parsing single endpoint at a
  time by a driver.

- Add a second patch that adds a function for parsing endpoints one at a
  time based on port and endpoint numbers.

  omap3isp: Drop redundant isp->subdevs field and ISP_MAX_SUBDEVS
  v4l: fwnode: Support generic parsing of graph endpoints in a device
  v4l: fwnode: Support generic parsing of graph endpoints in a single
    port
