Public bug reported:
Title: Built-in camera not working on MSI Prestige 13 AI+ Ukiyoe Edition A2VMG
(int3472-tps68470: No board-data found for this model)
Hardware:
- sys_vendor: Micro-Star International Co., Ltd.
- product_name: Prestige 13 AI+ Ukiyoe Edition A2VMG
- board_name: MS-13Q3
- CPU: Intel Core Ultra 9 288V (Lunar Lake), IPU7 (0x645d)
- Camera sensor: OV5675 (OVTI5675:00), PMIC INT3472:06 (TPS68470)
Software:
- Ubuntu 26.04.1 LTS, kernel 7.0.0-34-generic
Problem:
The camera does not work. dmesg shows:
int3472-tps68470 i2c-INT3472:06: TPS68470 REVID: 0x21
int3472-tps68470 i2c-INT3472:06: error -ENODEV: No board-data found for this
model
intel-ipu7 0000:00:05.0: no subdev found in graph
The IPU7 firmware loads correctly. The TPS68470 and OV5675 drivers are built
as modules (CONFIG_GPIO_TPS68470=m, CONFIG_REGULATOR_TPS68470=m,
CONFIG_COMMON_CLK_TPS68470=m, CONFIG_VIDEO_OV5675=m), but they never bind
because the PMIC probe fails.
Analysis:
Upstream has board data for "Prestige 13 AI+ Evo A2VMG" (MS-13Q3) in
drivers/platform/x86/intel/int3472/tps68470_board_data.c, matched with
DMI_EXACT_MATCH on the product name. My machine reports the product name
"Prestige 13 AI+ Ukiyoe Edition A2VMG" with the same board name MS-13Q3,
so the DMI match fails.
Request:
Please add a DMI match entry for "Prestige 13 AI+ Ukiyoe Edition A2VMG"
(board MS-13Q3) using the same board data as the Evo A2VMG, or relax the
match so both variants are covered.
Note: the system was installed from Ubuntu 24.04.3 and is being upgraded
to 26.04 LTS. The dmesg output above is from kernel 7.0.0-34-generic
(linux-hwe-7.0).
