charset=UTF-8 Content-Transfer-Encoding: 8bit Hi Tin, I tested this series on a Microsoft Surface Laptop 1, which has the same OV9734 behind an IPU3 CIO2. There an INT3472 discrete device provides the clock enable and the reset GPIO, and the _PR0 power resource of the sensor does nothing. I used 6.19.8-surface-3 with patches 1 and 2 applied (they apply with one-line offsets). Patch 3 does not apply there because the sensor list differs, so I added the same entry by hand. - the sensor probes and the chip ID reads back; - libcamera master with the OV9734 fixes from series 6330 [1] (IPU3 pipeline) streams 1280x704 NV12 at 30 fps; - the sensor is runtime suspended when idle; - unloading and reloading the module gives no kernel warnings; - v4l2-compliance 1.32.0 on the subdev: 45/46, only the known SUBSCRIBE_EVENT failure. Not tested: probe deferral at boot with these exact patches, and system suspend. Tested-by: Afonso Figuinha # Surface Laptop 1 (IPU3) I posted a duplicate series by mistake before I saw yours, and I have withdrawn it. Its patch 4 sets V4L2_SUBDEV_FL_HAS_EVENTS and uses the control event helpers, which fixes the SUBSCRIBE_EVENT failure. I can send it on top of your series, or you can fold it in, as you prefer.
