we made custom board with AM5728 processor with 2.8'' TFT LCD with ILI9341 chip.

LCD is designed with DPI 16bit RGB data.For this i enabled OMAP FB configurations in the kernel.what parameters are used in dts file.

Vijay,

You should make proper device tree configuration for display including resolution, timings and pinmux. You can refer to some existing configuration. Check display config in am437x-gp-evm.dts for example.
