IMX6 Parallel Camera Linux 4.4.3

Trying to work through getting a parallel camera working with Linux 4.4.3

Most of the posts here are for much older kernels, or very specific camera modules.

Is there a generic CSI parallel camera driver ?

A Device Tree Template for a generic parallel camera ?

what camera do you use? if you use the camera as board's, you can find the driver source code in the bsp, if you need to use specific camera, pls let me know it.

I do not know much about the camera.

It is connected following: SolidRun's app note

SR-uSOM-MX6-AN1-Connecting-Parallel-Camera.pdf

The actual camera is connected via an FPGA that transforms the Camera IO's to Parallel data

The Pixel clock is 74.25Mhz

Resolution is 1080p30 2200 clocks per line 1120 lines per frame

1920 active pixels, 1080 active lines The data format is 16bit YCbCr 4:2:2 single data rate

I have the pinctrl - pinmuxing in the devicetree correct - I beleive.

But I need a device configuration that will properly select the "camera": and connect it through the IPU

Below is snippets from my device tree related tot he camera.

I am asking if this look about right ? Or if there is a recommendation or app note someone is aware of for this ?
