Changes in v2:
- Add more description about pclk clock.
- Change minItems/maxItems to 2 for resets property.
- Better to handle "fsl,imx8ulp-mipi-csi2" variant.
- Move comment to the top of reset_control_deassert().
- Move dts patch as the last one.
- Add "fsl,imx8qxp-mipi-csi2" to compatible string list of csi node.
- Remove patch 5 in v1.
- Link to v1: https://lore.kernel.org/all/20250812081923.1019345-1-guoniu.zhou@oss.nxp.com

[PATCH v2 1/4] media: dt-bindings: nxp,imx8mq-mipi-csi2: Add i.MX8ULP compatible string

[Guoniu Zhou]

The CSI-2 receiver in the i.MX8ULP is almost identical to the version
present in the i.MX8QXP/QM. But have different reset and clock design,
so add a device-specific compatible string for i.MX8ULP to handle the
difference.

I don't see what we asked you for - restrict other variants.

Answer previous review:

"Or explain why old hardware has now 4
clocks. That explanation is missing."

[PATCH v2 3/4] media: imx8mq-mipi-csi2: Explicitly release reset

[Guoniu Zhou]

Call reset_control_deassert() to explicitly release reset to make sure
reset bits are cleared since platform like i.MX8ULP can't clear reset
bits automatically.

[PATCH v2 4/4] arm64: dts: imx8ulp: Add CSI and ISI Nodes

[Guoniu Zhou]

The CSI-2 in the i.MX8ULP is almost identical to the version present
in the i.MX8QXP/QM and is routed to the ISI. Add both the ISI and CSI
nodes and mark them as disabled by default since capture is dependent
on an attached camera.
