From 2d2815a7c224195e21e15c3e35c5343381918539 Mon Sep 17 00:00:00 2001 From: Robert Chen Date: Sun, 23 Jul 2023 22:54:55 -0400 Subject: mb/google/nissa/var/yavilla: avoid mipi camera LED blinking during launch Camera LED will blink several times as sensor is being probed during kernel boot. Configure _DSC to ACPI_DEVICE_SLEEP_D3_COLD so that driver skips initial probe during kernel boot and prevent privacy LED blink. BUG=b:292173903 TEST=Build and boot on Yavilly EVT unit. Verify & observe Camera LED blinking behavior.
