Re: [PATCH v10 3/4] dt-bindings: clock: imx95-blk-ctl: Define formatter child node schema

From: Guoniu Zhou <redacted>

The Camera CSR contains control registers for multiple CSI formatter IPs
at different register offsets. Each formatter is an independent hardware
block with its own clock input and media pipeline connection.

Define schema to allow formatter child nodes under nxp,imx95-camera-csr,
with 'reg' property specifying the formatter's register offset within the
CSR address space.

Signed-off-by: Guoniu Zhou <redacted>

- Add formatter subnode binding and camera-csr syscon example
- Update commit title and message
