In one of my infotainment project lcd panel interface has been connected as per the attached document. lcd display panel was up individually.

I mean we are getting the RGB data output of a imx287 by disabling the video decoder output and Video decoder RGB output by disabling the imx287 RGB lines.

 

We followed the /dev/fb framework for imx287 and configured the imx287 lcd pins functionality in arch/arm/mach-mx28/mx28evk_pins.c file. Other one we did as per the video decoder datasheet. Now we have to control the pin functionality in run time. i.e when we select video decoder we have to disable the imx287 lcdif pins functionality and vice versa. Please let me know is it feasible, if it is feasible please provide the which apis we have to use to chage the pin funciality on the fly.

 

Thanks and Regards
