Here's an issue from the customer may need your help:
Does SK-TDA4VM support 4lane for 4K resolution, 30fps MIPI data? And how is the pixel_rate calculated?
The customer has an external camera of 3856x2178, 30fps, raw12. They want to modify the drive of the imx219 to make the picture. However, the customer is not sure how the IMX219_pixel_rate in the drive and the link-frequencies in the device tree are calculated.
