Captured video would be out of sync when using the adv7280 with the BT.656-4 protocol. Certain registers (0x04, 0x31, 0xE6) had to be configured properly to ensure BT.656-4 compatibility. An error in the adv7280 reference manual suggested that EAV/SAV mode was enabled by default, however upon inspecting register 0x31, it was determined to be disabled by default.

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.
