From: Stephen Warren <swar...@nvidia.com> When tegradrm came along, I chose not to allow HDMI ports to be enabled on boards that had built-in LCDs, since tegradrm had issues when multiple outputs were enabled, and I wanted to bias towards internal LCDs working first. However, that bug has now been squashed, so we can now enable HDMI anywhere it works. In fact, enabling the LCD outputs may be delayed a while, as we sort out power sequences vs. generic panel drivers vs. ...
Note that if you have a bootloader that turns on the LCD, and the kernel doesn't have the LCD output enabled (which is always true right now), the kernel doesn't disable the LCD scanout. I've filed a bug internally for Mark Zhang to look into this. However, the HDMI output should still work fine; the LCD will just display various odd things. In theory, we could enable HDMI on Cardhu, but I haven't in this series because doing so causes memory fetch underflow (at least for some external display resolutions) (since the LCD is enabled too, and not turned off) since we aren't programming the memory controller correctly yet. As such, HDMI doesn't actually work well on Cardhu yet.
