Current DW HDMI PHY code never prepares and enables PHY clock after it is created. It's just used as it is. This may work in some cases, but it's clearly wrong.

Current "old" method to find engine worked pretty well for DE2. However, it doesn't work when TCON TOP is between mixer (engine) and TCON. TCON TOP has multiple input ports, but current engine search algorithm expects only one. This can be fixed by first looking for output port id and selecting matching input by subtracting 1 for the next round. This work even if there is only one input and output.

The meaning of the mode_config max_width/height fields has not been entirely clear. They are used both as the max framebuffer dimensions, and they are also used by drm_mode_getconnector() to filter out any mode whose hdisplay/vdisplay exceed those limits. Let's put it in writing that max_width/height only refrer to the max framebuffer dimensions, and should those be higher than the hardware limits for display timings the driver must validate the latter using some other means. We'll keep the max_width/height usage in drm_mode_getconnector() because setcrtc treats hdisplay/vdisplay also as the primary plane width, and having a plane bigger than the max fb size doesn't make much sense (if we ignore scaling that is). It all works out fine as long as the max fb dimensions are at least equal to the max timing limits. If the opposite were true we may want to rethink what drm_mode_getconnector() does. Maybe do the mode filtering only for non-atomic userspace?
