From 28d1e47694aff751cfb1d86a2f9701f0a22e5f1e Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Fri, 4 Jun 2021 23:22:16 +0200 Subject: media: dt-bindings: adv7180: Introduce 'adv,force-bt656-4' property Captured NTSC video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) need to be configured properly to ensure BT.656-4 compatibility. Introduce the 'adv,force-bt656-4' property to allow the ADV7280 behavior to be consistent with the ADV7180, where BT.656-4 timing is used by default.
