Hi,

Re-posting as previous posting was rejected due to length.

Forgot to mention, DPI pins are connected to TDF19988 chip for HDMI conversion.

I have build the driver for it from https://gitorious.org/thierryreding/linux/source/e7792ce2da5ded80861db787ace9b57ecf7bc96c:drivers/gpu/drm/i2c/tda998x_drv.c. Is this the correct driver for it?

Also I am trying to use the generic-dpi-panel driver for this with OMAP5. It seems I also need to add support for TDF19988 somewhere in omapdrm or lcd/panel driver by calling drm_i2c_encoder_init to initialize it. Can I use somecode from ticldc driver or driver itself? Could you please give some inputs, how should I proceed further to adding support for TDF19988 for which the input is coming from DPI interface?

Thanks & Regards,

Vikash

Hi Tomi,

How could I confirm for OMAP5 DPI support apart form enabling CONFIG_OMAP2_DSS_DPI and CONFIG_PANEL_GENERIC_DPI? Enabling mentioned config builds components from Kernel\drivers\video\omap2\dss and kernel\drivers\video\omap2\displays only. Is there any support needs to be available under kernel\arch\arm\mach-omap2?

Regards,
Vikash

Does the kernel have support for OMAP5 DPI? I remember there were some
bits that had to be added to make it work.
