HELP: Porting NEC LCD Driver to DM3730 Custom Board

Hi e2e.ti users,

I need help about porting LCD to Linux. Our custom board is similar to Mistral's OMAP3EVM and has some differences. One of them LCD, we are using NEC's NL8048BC19-02 7" LCD. Main difference between omap3evm's SHARP LS037V7DW01 LCD and our NEC's NL8048BC19-02 LCD is Data Enable type. Mistral's EVM uses HSYNC and VSYNC signas for data enable but NEC's LCD uses ACBIAS Data Enable signal. So if i configure XRES, YRES and Pixel_Clock, The LCD wouldnt run correctly. I searched for a new driver but i couldnt find the correct one, only i found nec nl8048hl11-01b driver. But this ones drives HSYNC and VSYNC signals to. Is there any way to modify this driver for NEC's NL8048BC19-02?  Or where can i found a compatible linux driver with  NEC's NL8048BC19-02 ?

Best regards

Ahmet
