From 60753d752ea3daa7be131045a0996b142fcae6d4 Mon Sep 17 00:00:00 2001 From: David Plowman Date: Tue, 11 May 2021 12:57:22 +0100 Subject: [PATCH 396/552] media: i2c: ov5647: Correct minimum VBLANK value Trial and error reveals that the minimum vblank value appears to be 24 (the OV5647 data sheet does not give any clues).
