[U-Boot] [PATCH] powerpc/t1040qds: Remove Video - HDMI support
From: Wang Dongsheng dongsheng.wang@freescale.com
We should remove this support. First, there is not any documents to say we need to support this feature, and kernel also not support this feature. Second, Kerneal not support this on T1040QDS, so if we open it in u-boot, FPGA will be changed and that will affect deep sleep feature.

Hello Dongsheng,
We do have requirement to support this that's why code development was done. Also , what is the dependency of deep-sleep on this. Please elaborate And if something is broken, we should fix it. Instead of removing the feature.
If we have, why kernel doesn't support DIU on T1040QDS? That I must remove it reason.

Hello Dongsheng,
We do have requirement to support this that's why code development was done. Also , what is the dependency of deep-sleep on this. Please elaborate And if something is broken, we should fix it. Instead of removing the feature.
If we have, why kernel doesn't support DIU on T1040QDS? That I must remove it reason.
Guys,
Do we have an agreement if this feature should be kept or removed?

Hi York,
Sorry for late response. We don't need to remove this patch. Please keep this patch.

Hi York,
Sorry, I'm wrong. Please drop the "powerpc/t1040qds: Remove Video - HDMI support" patch.
Cause of we need to keep u-boot support to QDS-DIU feature.

Because no one added that support yet. You should finish the job by fixing the kernel.

We should remove this support. First, there is not any documents to say we need to support this feature, and kernel also not support this feature. Second, Kerneal not support this on T1040QDS, so if we open it in u-boot, FPGA will be changed and that will affect deep sleep feature.

Hold on this. Let's sort it out before removing this feature. It was developed for a reason.
