Hi m.c.

adv7535 mipi-hdmi bridge is used for i.MX8M Mini EVK

fsl-imx8mm-evk.dts\freescale\dts\boot\arm64\arch - linux-imx - i.MX Linux kernel 

its driver checks supported resolutions in struct fb_videomode (mxc_edid.c)

adv7535.c\mxc\fbdev\video\drivers - linux-imx - i.MX Linux kernel 

mxc_edid.c\mxc\fbdev\video\drivers - linux-imx - i.MX Linux kernel 

Best regards
igor
