Platform is using i.MX6 to interface to ADV7280.
Please advise where to download lunix driver for ADV7280.
ADV7280 driver support is part of the official upstream Linux kernel distribution.
But be aware that the iMX6 video capture drivers are not part of the upstream Linux kernel and the drivers found in the Freescale/NXP BSP use a custom interface that is incompatible with the interface supported in the upstream kernel. So you'll need to do some work to adopt the driver to the iMX6 platform.
