This serie adds support for the GalaxyCore GC2145 sensor.
Initialization is based on scripts provided by GalaxyCore,
allowing 3 fixed configurations supported for the time being.

Minimum controls have been added in order to allow it to
be successfully used with libcamera and dcmipp driver (under
review) on STM32MP13 platform.

The sensor also supports Bayer formats which will be added
later on.

v5: - serie rebased on top of master branch of tree sailus/media_tree.git
      in order to use v4l2_subdev_state_* functions

v4: - bindings: add link-frequencies & correct description
    - driver: add link-frequency ctrl and fix pixelrate
      and check for link-frequency dt properties
    - driver: correct wording / email / add datasheet link

v3: - fix copyright year
    - add more gc2145_ func or variable prefixes
    - removal of colorspace within struct gc2145_format
    - use 1X16 formats since driver is supporting CSI-2 interface only
    - use msleep instead of usleep_range
    - add pm_runtime_ last_busy & autosuspend handling
    - only start streaming AFTER applying ctrls
    - correct RGB565 format to generate _LE instead of _BE
    - perform pm_runtime configuration prior to v4l2_async_register_subdev_sensor
    - remove frame_interval handling and expose HBLANK/VBLANK ctrls
      instead

v2: - split vendor-prefixes update into a separate commit
    - correction into dt-bindings (description, const i2c address,
      lowcase of supplies, node naming
    - correct KConfig (avoid VIDEO_V4L2_SUBDEV_API, V4L2_FWNODE and add
      V4L2_CCI_I2C)
    - usage of v4l2-cci framework for accessing to device registers
    - correction in power-on / power-off sequences and update
      usleep_range delay
    - detail MIPI configuration and stop register access to stop
      streaming
    - removal of SYSTEM_SLEEP_PM_OPS (and streaming variable)
    - various small fixes, typo, oneline functions
    - removal of useless HBLANK control considereing that RAW isn't
      supported for the time being
    - removal of RAW parts
    - usage of dev_err_probe

+description:
+  The Galaxy Core GC2145 is a 2 Megapixel CMOS image sensor, for mobile
+  phone camera applications and digital camera products. GC2145 incorporates a
+  1616V x 1232H active pixel array, on-chip 10-bit ADC, and image signal
+  processor allowing AE/AWB/interpolation/de-noise/color-conversion and
+  gamma correction. Bayer RGB, RGB565 and YCbCr 4:2:2 can be provided by the
+  sensor. It is programmable through an I2C interface. Image data is sent
+  either through a parallel interface or through MIPI CSI-2.

Addition of support for the Galaxy Core GC2145 XVGA sensor.
The sensor supports both DVP and CSI-2 interfaces however for
the time being only CSI-2 is implemented.

Configurations are currently based on initialization scripts
coming from Galaxy Core and so for that purpose only 3 static
resolutions are supported:
 - 640x480
 - 1280x720
 - 1600x1200

Normally tristate would go before select.
