You have to set status to okay here.

Sorry, this is actually the job of bootloader, so it's all good.

With that fixed, you can add:

No fixing needed for R-b tag.

Is it really needed? The DE2 HDMI driver can be loaded and make this pretty 
much obsolete.

DE2 and HDMI driver could read current settings from that node and implement 
flicker free transition. However, that's not supported yet. Another use case is 
to optimize kernel size to minimum for storing it in SPI flash by removing DRM 
driver if simplefb is good enough.

Anyway, patch looks good. Thanks!
