Dear NXP Team,

We are developing an application that requires DSI to HDMI support for a resolution of 1280x800 on the i.MX8MM processor.
We are seeking your guidance on achieving this functionality.

Current Challenge:
We reviewed the drm_edid.c driver file within the Linux kernel source code (https://github.com/nxp-imx/linux-imx),
specifically the edid_cea_modes variable. This variable appears to lack native support for the 1280x800 resolution.

Driver Support:
Does NXP offer a driver solution for enabling DSI to HDMI with 1280x800 resolution on the i.MX8MM platform?
We would appreciate any recommendations or workarounds you could suggest regarding driver support for this specific resolution.
ADV7535 Chip Compatibility:

We are also exploring the viability of using the ADV7535 chip in conjunction with the i.MX8MM to achieve DSI to HDMI with 1280x800 support.
Can you confirm if the ADV7535 chip is compatible with this configuration and resolution on the i.MX8MM platform?

Thanks.
