We want to eventually get rid of the connector->panel.fixed_mode pointer so avoid using it during DSI property setup. Since this all happens during the encoder init we already have the fixed_mode around, just pass that in. Signed-off-by:

Rename the PIPECONF refresh rate select bits to be less cryptic. Also nothing eDP specific about these as they also select between FP0 vs. FP1 for the DPLL and thus can be used to change the refresh rate on other output types as well. Signed-off-by:

Remove the comment specifying the exact formulat for calculating the DPLL frequency from the *_find_best_dpll() functions.

Unify vlv/chv with earlier platforms so that the sturct dpll::dot represents the /5 clock frequency (ie. DP symbol rate or HDMI TMDS rate) rather than the *5 fast clock (/2 of the bitrate). Makes life a little less confusing to get the same number back in .dot which we fed into the DPLL algorithm. v2: Actually just include the 5x in the final P divider Do the same change to the hand rolled gvt code v3: Missed a few *5 in *_find_best_dpll() Reviewed-by: -

When using bigjoiner it's useful to know the offset of each individual pipe in the whole set of joined pipes. Let's include that information in our PIPESRC rectangle. With this we can make the plane clipping code blissfully unaware of bigjoiner usage, as all we have to do is remove the pipe's offset from the final plane destination coordinates. v2: Use intel_bigjoiner_num_pipes() Signed-off-by:

Since we now have the bigjoiner_pipes bitmask the boolean is redundant. Get rid of it. Also, populating bigjoiner_pipes already during encoder->compute_config() allows us to use it much earlier during the state calculation as well.

Now that we track framestart_delay in the crtc state with readout and state checker support we can remove the explicit framestart_delay sanitation code. Also I'm not convinced reprogramming this while the pipe is running is even valid. CHICKEN_TRANS (hsw+) and TRANS_CHICKEN2 (cpt+) docs at least make no mention of double buffering which seems to imply that live reprogramming is not supported. On older platforms PIPECONF and PCH_TRANSCONF (ibx) are double buffered though, so might be that we could do this on the older platforms. But doesn't really make sense to special case old platforms for this. So from now on if the BIOS has misprogrammed this we shall simply do a full modeset at boot to fix it up. Such systems will of course lose fastboot, but I think less code (and less uncertainty what reprogramming this on a running pipe will even do) outweighs that. Signed-off-by:
