[PATCH v5 06/14] media: vimc: cap: Add handler for multiplanar fmt ioctls

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

 



Add functions to handle multiplanar format ioctls, calling
the generic format ioctls functions when possible.

---
Change in v5: none

Change in v4:
- Split from multiplanar parameter commit
- Use `IS_MULTIPLANAR` instead of `multiplanar`
- Move "Functions to handle..." to commit 5

Change in v3:
- Remove functions that only did the `IS_MULTIPLANAR(vcap)` check
- Squash with multiplanar parameter commit

Change in v2:
- Fix alignment
