From 89a3ae3d801c0afb3eb97c19972a6451e4233ced Mon Sep 17 00:00:00 2001 From: erin liang Date: Tue, 2 Sep 2025 14:18:44 +0800 Subject: [PATCH] mb/google/trulo/var/pujjolo: Update GPP_D15 setting During the ACPI initialization phase at boot, the driver is pulled, causing the LED of the WFC camera flash. This issue can be resolved by replacing GPP_D15 with GPP_D16 in the mipi settings. BUG=b:434106137 TEST= Build and boot to OS, and check the Chromebook logo will not flash Change-Id: I2fce7f7c9c5c852efbdef3e5ef757cab3433f4c6 Signed-off-by: erin liang Reviewed-on: https://review.coreboot.org/c/coreboot/+/89014 Reviewed-by: Eric Lai Tested-by: build bot (Jenkins) --- .../google/brya/variants/pujjolo/overridetree.cb | 9 +++------ 1 file changed, 3 insertions(+), 6 deletions(-) diff --git a/src/mainboard/google/brya/variants/pujjolo/overridetree.cb b/src/mainboard/google/brya/variants/pujjolo/overridetree.cb index 2b8d56cf10..423b79fa6e 100644 --- a/src/mainboard/google/brya/variants/pujjolo/overridetree.cb +++ b/src/mainboard/google/brya/variants/pujjolo/overridetree.cb @@ -439,18 +439,15 @@ chip soc/intel/alderlake register "max_dstate_for_probe" = "ACPI_DEVICE_SLEEP_D3_COLD" # Controls - register "gpio_panel.gpio[0].gpio_num" = "GPP_D15" # EN_PP2800_WCAM_X - register "gpio_panel.gpio[1].gpio_num" = "GPP_D16" # EN_PP1800_PP1200_WCAM_X + register "gpio_panel.gpio[0].gpio_num" = "GPP_D16" # EN_PP2800_WCAM_X and EN_PP1800_PP1200_WCAM_X # _ON - register "on_seq.ops_cnt" = "2" + register "on_seq.ops_cnt" = "1" register "on_seq.ops[0]" = "SEQ_OPS_GPIO_ENABLE(0, 5)" - register "on_seq.ops[1]" = "SEQ_OPS_GPIO_ENABLE(1, 5)" # _OFF - register "off_seq.ops_cnt" = "2" + register "off_seq.ops_cnt" = "1" register "off_seq.ops[0]" = "SEQ_OPS_GPIO_DISABLE(1, 0)" - register "off_seq.ops[1]" = "SEQ_OPS_GPIO_DISABLE(0, 0)" device i2c 0C on probe WFC WFC_MIPI_OVTI8856
