The Snapdragon Lenovo T14s Gen6 can be bought with a number of different panels. This patch series adds support for the OLED model which has a Samsung ATNA40YK20 panel.
With this patch series, the backlight of the OLED eDP panel does not illuminate since the brightness is incorrectly read from the eDP panel as 0 (to be clear this is not a regression). This will be fixed in a follow-up patch series as it does not block the device tree patches.
