Subject: media: v4l2-mediabus: Drop V4L2_MBUS_CSI2_CONTINUOUS_CLOCK flag
X-Git-Tag: v6.1-rc5~1763^2~139
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b9f7caa7753ad185e0dc7afb3ae4bd423d11f5c0;p=platform%2Fkernel%2Flinux-starfive.git

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.
