[PATCH 07/14] media: qcom: camss: csid-680: Enable RDI SOF tracking
From: bryan . odonoghue
Date: Thu Oct 29 2026 - 06:02:00 EST
From: Bryan O'Donoghue <bryan.odonoghue@xxxxxxxxxx>
Similarly to the sm8650 we can quite easily switch on V4L2_EVENT_FRAME_SYNC
for x1e/x2e which uses csid-680.
Do so now.
