From a21d0a1073907b5a87fd31fa195456523d616165 Mon Sep 17 00:00:00 2001 From: Matt DeVillier Date: Fri, 1 Sep 2017 14:15:08 -0500 Subject: google/lulu,gandof: set kb backlight on boot Set keyboard backlight to 75% on boot, except when resuming from S3. This enables the backlight at a reasonable level prior to the OS driver taking over, providing early proof-of-life and enhanced usability in grub etc. Uses same method as other google boards with a keyboard backlight (chell, link, samus). 75% value determined based on user feedback. TEST: boot google/lulu,gandof boards, observe keyboard backlight enabled in pre-OS environment.
