3.5” TFT-LCD with Touch Panel Module Model No : WXCAT35-TG3#001 BBB(DEBIAN)

HI all.

Can any budy tell me about anything i miss out above LCD configuration because my LCD is not working

we are interfacing LCD with beagle bone black

LCD D0 to D15 --------------------------------LCD0 to LCD15
LCD pin 14 /RESET-----------------------P9.25
LCD pin 15 /CS---------------------------P9.28
LCD pin 16 SCL---------------------------P9.31 SPI1_SCLK
LCD pin 17 SDI---------------------------P9.29 SPI1_D0
LCD pin 42 IHS(Horizontal sync)--------P9.19 LCD_HSYNC
LCD pin 43 IVS (Vertical Sync)----------P9.27 LCD_VSYNC
LCD pin 44 CLK (Clock )------------------P9.28 LCD_PCLK
LCD pin 58 DEN (Data Enable)-----------P9.30 LCD_DE

according to that i modified with dts dile for 320x270 (BB-BONE-LCD4-01-00A0.dts)
