Hi Esteban,
Usually the used pattern is vendor,ddic+panel-model
novatek,nt37703-motorola-bronco
...but motorola bronco isn't the model of the panel.
My recommendation - look at some video of screen replacement, stop at moment
when FLEX cable from panel is visible and that's where the panel model usually
is.
I somewhat doubt the panel model would be located in the FPC cable.
I did search anyway but didn't find anything of interest. And I'm not
willing to risk damaging the display flex or the battery of my
development device just for a possibility either.
No-one asks you to disassemble the device :)
Sadly, I haven't found any video doing display replacement either.
In worst case such as this I assume it make sense keep the phone model in the
compatible until panel codename is found.
For the compatible pattern I used the implemented pattern for the
NT36523 TDDI, which is also used for other ICs such as the RM69380.
So, I believe it should be okay to leave the compatible as is.
I would like to hear a word from Neil first. In similar cases like this would
make sense to have one way defining these compatible strings used in phones.
bit I missed in the review the part:
+ compatible = "motorola,bronco-tianma-v2-nt37703",
"novatek,nt37703";
Unless the driver is able to auto-detect the connected panel (unlikely),
novatek,nt37703 doesn't make sense. The DDIC without the panel is useless.
For example, in sdm845-oneplus-fajita and enchilada, we have the generic
compatible because it was introduced before, so it's kept for compatibility
reasons. There is no need to do that here.
Thanks
