[PATCH v2 0/3] media: i2c: imx412: Modernize driver with CCI and streams API

[Elgin Perumbilly]

This series modernizes the imx412 driver by:

1. Converting to the common CCI (Camera Control Interface) register
   access helpers, which simplifies the code by removing custom I2C
   register access functions.

2. Switching to use the V4L2 sub-device state lock instead of a
   private mutex, improving integration with the V4L2 framework.

3. Migrating from the legacy s_stream callback to the modern
   enable_streams/disable_streams callbacks, providing better support
   for multiplexed streams.

These changes reduce code complexity, improve maintainability, and
align the driver with current V4L2 best practices.

v1 -> v2

In Patch 2/3:
