Subject: [PATCH v2 0/4] media: omap3isp/et8ek8: Add CCP2 CRC configuration support

This patch series provides support for configuring CRC checksum via device tree
for et8ek8 sensor and OMAP3 ISP receiver.

Previously, CRC was hardcoded to enabled (1) in the sensor driver and ISP
receiver. This series makes it configurable through DT, allowing both
sides to be aligned, as both must use the same CRC setting for proper CCP2
communication.

Changes maintain backward compatibility by defaulting CRC to 1 when the
property is not specified in the device tree.

The series also converts both device tree bindings from TXT to YAML
schema format, as required.

Changes in v2:
- Fixed broken patch threading
- Added receiver support for reading crc from device tree
- Converted both sensor and ISP bindings from TXT to YAML format
- Both sensor and ISP endpoints can now be configured consistently via DT

  media: i2c: et8ek8: et8ek8_driver: add support for crc configuration
    via device tree
  dt-bindings: media: i2c: et8ek8: document missing crc as optional
    property
  media: platform: ti: omap3isp: isp: read crc configuration from device
    tree for CCP2
  dt-bindings: media: omap3isp: document missing crc as optional
    property
