From f7c7d6ccc503c0a5f4e5debb570b55bf2eb24c73 Mon Sep 17 00:00:00 2001 From: Sakari Ailus Date: Thu, 17 Dec 2020 19:27:08 +0100 Subject: [PATCH] media: uapi: Add an entity type for Image Signal Processors 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).
