From feb5d10061927639cc691207d4c0f408f5578123 Mon Sep 17 00:00:00 2001 From: Daniel Kang Date: Wed, 1 Jul 2020 16:49:34 -0700 Subject: mb/google/volteer: Fix world-facing camera LED is always on issue Volteer world-facing camera has a privacy LED and it is supposed to be turned on only when the camera is being used. But the LED is always on and this is to fix the issue. RCAM_SNR_PWR_EN (RearCAMera_SeNsoR_PoWeR_ENable) GPIO, which controls the world-facing camera LED, was not in the power-up and power-down sequence definitions and this caused the issue. BUG=b:160341981 BRANCH=none TEST=Build and boot volteer proto 2 board. Start a camera app and check the world-facing camera LED is only turned on only when the camera is working.
