Hi all,
Is there support for hdmi display for sabresd ( or sabrelite) in linux kernel 3.14? I have enabled drm hdmi support in kernel 3.14 configuration but still i cannot see anything on HDMI display. [ The fbset command shows all the clock values (hsync, vsync and pixel rate) as zero]
Solved! Go to Solution.
You should use this kernel, which is based on 3.15-rc1:
https://git.kernel.org/cgit/linux/kernel/git/shawnguo/linux.git/log/?h=for-next
It has HDMI support for sabresd since last week.

Thanks Fabio. I tested the kernel (3.14-rc3) with the above patch for hdmi in sabresd and hdmi is working (though it is not working when the hdmi cable is connected when the system boots). Also I can see "lvds" display driver "ldb" is inserted in the dmesg, but no log for LCD display driver. Is there support for LCD display in the above kernel?
For parallel display to work you would need to add support for it in the dts file.
Take a look at arch/arm/boot/dts/imx53-qsb.dts for reference (Search for compatible = "fsl,imx-parallel-display";)
If it works for you, please send the patch for linux-arm-kernel list.
