There are several different models of N116BGE. According to the commit that added innolux_n116bge_mode [0], this N116BGE is for the eDP variety.

drm/panel: simple: Add Innolux N116BGE panel support
The clock and htotal values from add by that patch are out of spec according to the datasheets I have seen for the eDP N116BGE (-EA2 and -EB2).
This patch changes the values to the "Typ" values on the datasheet.

Thierry,
It is possible that your timings were correct for the panel you are using on the norrin reference board. In that case I'm happy to upload a new patch that creates a new panel entry. However, I'm pretty sure we are using the same N116BGE.

Hi Thierry,
Congratulations! I saw in one thread that you said you are out on paternity leave.
You mentioned that you would be back around v3.17-rc6, which should be soonish, so just a gentle ping on this patch for when you return.
Thanks, -Daniel

I'm back to work starting today but catching up on a lot of email, so it might take me a little to get to the bottom of this.

This patch changes the values to the "Typ" values on the datasheet.
The original patch was based on -E42 of the datasheet. But I can run some tests to see if the timings in this patch work on the panel that I have. If so I guess the easiest would be to apply this.
It shouldn't matter all that much since the panel has EDID if I remember correctly. The modes parsed from EDID should take precedence over the fixed mode. If they don't then that's a bug.

No, I didn't even try with your values, actually. Out of spec just means that the numbers do not fall between Min and Max on the datasheet:
72.6 <= DCLK <= 80.24 vs. 71 1506 <= htotal <= 1716 vs. 1500
This patch changes the values to the "Typ" values on the datasheet.

It shouldn't matter all that much since the panel has EDID if I remember correctly. The modes parsed from EDID should take precedence over the fixed mode. If they don't then that's a bug.
The driver I am testing this with does not yet support reading the EDID over eDP, so I am using the fixed values for now.

Ew... you should get a better driver, then. =)

Took me a while longer to test this than I had expected. Turns out the Tegra132 Norrin board that I have works with the timings you provide in this patch too, so I'm going to apply this patch.
