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.
