Linux/DRA746: How to enable vin4B for video input?

Part Number: DRA746
Other Parts Discussed in Thread: DRA742

Tool/software: Linux

HI TI,

I'm using the J6 CPU EVB board, borad info:

CPU : DRA752-GP ES1.1
Model: TI DRA742
Board: DRA74x EVM REV G.0

And I have make two camera adapters and two sensor drivers: for VIN1A and for VIN4B, camera output is noraml 1280x720, YUV422-8bit(has PCLK VSYNC HSYNC siginal pin).

When I use VIN4B, there is no preview data, I check '0x48995A70', seems there is no interrupt.

How to enable VIN4B(how to configure pinmux and configure dts)?

VIN4B camera adapter is connected to the 'EXP_P1' connecter of J6 CPU board.
