From 2c307a0bedfeecd932531387efcc4f66381f6d56 Mon Sep 17 00:00:00 2001 From: Hung-Te Lin Date: Wed, 20 Feb 2019 14:31:23 +0800 Subject: mb/google/kukui: Initialize display Many devices in Kukui family will be using MIPI panels, which needs hard-coded EDID and initialization commands. And because each device may have its own layout and ID, there should be very few devices sharing same panel configuration. As a result, we want to put panel data (EDID and init commands) into board-specific modules, provided by `get_panel_description` function. The panel numeric ID is identified by ADC 2, and is currently available as higher 4 bits of sku_id(). After ID is retrieved, the get_panel_description should return a reference to the EDID and table of init commands. The default implementation is to simply return NULL, and the data for real devices should be provided by panel_*.c in further commits.
