The error reported is on the wrong patch. Not sure why, but the problem
is here. With 'additionalProperties: false', this property is not
factored in and is considered unknown. That can be fixed using
'unevaluatedProperties', but instead, move this to the top level
'properties'.

The first example is enough.
Hi Marijn, thanks for your patch!

Samsung S0FEF01-M AMS605DK01? I would more expect the compatible strings to be excluding the DDIC name, like: samsung,ams605dk01 ...but it's not like the vendor is helping us here, so I'm practically fine either way. They are clearly using the S0FEF01-M display controller. Yours, Linus Walleij

Unfortunately I'm not that familiar with display manufacturers and panel assemblies. Most of the what I presume to be panel names were gleaned from online screen replacement photos; those don't ever include the DDIC name. Those mostly come from the DTS though isn't mentioned exactly for every phone (only the first two in the DTS name). > They are clearly using the S0FEF01-M display controller. So you're implying or certain that these panel names here are always bundled with exactly the same controller (making the SOFEF01 part "redundant" in the compatible)? Also, divergence of the driver commands got significant with the last two panels / three phones, though that might be down to vendor configuration/calibration. - Marijn > Yours, > Linus Walleij

Yes that's what I suspect. See my comment in the driver that all s6e* panels are suspected to be some s0fef00/1 variant. > Also, divergence of the driver commands got significant with the last two panels > / three phones, though that might be down to vendor configuration/calibration. That's kind of normal. The defaults suffice for a while, then engineers want to start poking at different voltages to the display to improve and tweak things. Yours, Linus Walleij

Do you still want me to drop it from the compatible, but definitely keep it in the driver filename unless we unify all of the drivers (hopefully in a later patch)? > > Also, divergence of the driver commands got significant with the last two panels > > / three phones, though that might be down to vendor configuration/calibration. > > That's kind of normal.

Makes one wonder if the changes are down to the panel used, or vendor tuning when they started using these panels in their phones. To note, I think I booted all these phones on the "original" SOFEF01 driver without problems, before ultimately implementing all diverging commands because I don't know if they're defaults, related to color tuning, timings, thermals, manufacturer tolerances or anything else. - Marijn

The compatible should be as precise as possible, so indicate the assembled display with display controller, typically samsung,ams605dk01 etc, then the Linux driver is basically a Linux intrinsic matter, but we would name that after the display controller so as to make the basis of code sharing obvious between the compatibles. > > > Also, divergence of the driver commands got significant with the last two panels > > > / three phones, though that might be down to vendor configuration/calibration. > > > > That's kind of normal.

Yeah a datasheet would really help :/ Samsung, if you're reading this, you know what to do: give us the datasheets, pretty please with sugar on top. Yours, Linus Walleij
