Just thinking hypothetically.. what if some future device had two hdmi controllers. Then you'd want two instances of the same display object.
Although it seems this API is just internal to the DRM driver (which I had not realized earlier), so it should be pretty easy to change later if needed.
You are right. I guess we should consider multiple instances to display object because the Exynos hardware has two display controllers and also each display controller needs one display panel with sharing same driver. thank you for your pointing. :)
Two HDMI and two FIMD is different. even though exynos4 supports the two display controller. it has only one HDMI port and now there's no device to use it. Of course if new device uses it. it will support it. I mena currently make it simple and make it TODO list.
yeah.. since it is just an API internal to the driver, and not external (as I initially mistakenly thought), I don't think it is an immediate issue. It should be easy enough to change later if you, for example, later had hw w/ two HDMI ports.
