Hi All! I am working with Qualcomm Snapdragon820 Board and try to port a new display. My board is APS8096 Dev Board with Android 8.1 on it. There is a Display Porting Guide by Qualcomm however for Snapdragon410. Still very useful, easy to adapt for SnapD.820.
Still there are things that make me confuse : *1.* Display/ Panel / Display controller ... They , all , are used interchangeably or in a confusing way.Not only in the guide but in some other document by other vendors also . As I understand from the point of hardware Display = Panel + Display controller + Backlight Module (opt) + Touch screen controller(opt) Is it right ? Are they also mentioned with these names in the software-level /AOSP Level ? Is there a standart naming convention i have missed or am I right to be confused ? *2*. *The main question* : *how to port display controller and touch contrtoller * It is clear that how panel settings (resolution ,color depth etc..) are imported/introduced to the system (via device tree and header for bootloader) . However , also related to the first question , there is no clue how *display controller* or *touch controller* (it is relativly reasonable not to be mentioned while it is not a mandatory part of display.) should be ported . I have dived into the device trees and the kernel for existing display related setting and find some entries and drivers for display controller and also touch controller. They shoud be also introduced to the system , right ? Any clue would be appreciated .
