Hello,
This patch series is an update to the first V4L2 request API RFC series for
the VSP1 driver.
The main change compared to v1 is the refactoring of the pipeline in patches
51 to 56. The patch that implements support for the request API in the VSP1
driver itself is missing from this RFC as it hasn't been properly tested yet
after being rebased on top of v2. I'll fix it ASAP.
The series isn't ready for merge yet. In particular it needs to be rebased on
top of v4.5-rc1. This will likely cause issues due to the media controller
framework rework that got merged in mainline. I can't estimate at this time
how long an acceptable solution will take to be developed.
