From b9f7caa7753ad185e0dc7afb3ae4bd423d11f5c0 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Wed, 5 Jan 2022 21:15:58 +0100 Subject: [PATCH] media: v4l2-mediabus: Drop V4L2_MBUS_CSI2_CONTINUOUS_CLOCK flag MIPI CSI-2 continuous and non-continuous clock modes are mutually exclusive. Drop the V4L2_MBUS_CSI2_CONTINUOUS_CLOCK flag and use V4L2_MBUS_CSI2_NONCONTINUOUS_CLOCK only.
