a=openpgp; fpr=F18BDC8B6C25F90AA23D5174634DC4F0687046F8 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 (to be clear this is not a regression). This is fixed in [0].
