Subject: media: uapi: Add an entity type for Image Signal Processors Author: Sakari Ailus <[email protected]> Date: Thu Dec 17 19:27:08 2020 +0100 Add and document a media entity type for Image Signal Processor devices. Surprisingly we didn't have one, so add one now. More or less all ISP drivers should use this type instead of what they currently are using (or not using anything).
