IMX6QP Sabre Auto 1920x720 Resolution Problem

I compile a special kernel supported by yocto for imx6qp. 1920x720 resolution is not defined in this kernel system. The supported resolution values are the below.

U:1280x720p-120 U:1280x720p-100 
U:1920x1080p-30 U:1920x1080p-25 U:1920x1080p-24 U:1920x1080p-50  U:1440x576p-50 U:1440x576p-50 U:1440x288p-50 U:1440x288p-50  U:1280x720p-50 U:720x576p-50 U:720x576p-50 U:1920x1080p-60  U:1440x480p-60 U:1440x480p-60 U:1440x240p-60 U:1440x240p-60  U:1280x720p-60 U:720x480p-60 U:720x480p-60 U:640x480p-60

U-boot parameter:

setenv my_bootargs_sata setenv bootargs console=\${console},\${baudrate} root=/dev/sda2 video=mxcfb0:dev=hdmi,1920x720M@60,if=RGB24

Since the 1920x720 resolution value is not included here, it takes into consideration the nearest value of 1920x1080.

How do I compile a kernel with custom resolution? (1920x720)
