Subject: [PATCH v3 0/2] i.MX8MQ EVK: Enable dual OV5640 cameras
Date: Fri, 29 May 2026 21:23:32 +0800 [thread overview]
Message-ID: <20260529132334.3333294-1-robby.cai@nxp.com> (raw)
This series enables dual OV5640 camera support on the i.MX8MQ EVK.
The DT describes two sensors connected to different MIPI CSI-2
interfaces, while both sensors share a common reset GPIO.
To properly handle the shared reset line, the OV5640 driver is updated
to use the reset control framework instead of directly controlling the
GPIO.
Changes in v3:
- Add OV5640 driver changes to use reset control framework for shared reset
- Drop GPIO hog for reset in DTS
Link to v2: https://lore.kernel.org/imx/20260515111143.2980956-1-robby.cai@nxp.com/
Changes in v2:
- Address comments on MIPI clock configuration (Frank, Sebastian):
drop the first patch and consolidate the correct clock configuration
into the second patch
- Address comments from sashiko:
* Use MEDIA_BUS_TYPE_CSI2_DPHY instead of a literal value
* Fix a probe-order dependency related to reset handling. Switch to
software reset, as the shared hardware reset line prevents
independent reset when both cameras are enabled due to a board
design limitation
* Fix incorrect voltage value in the reg_2v8 node
