This driver handles the MAX96717 serializer in tunnel mode.
All incoming CSI traffic will be tunneled through the GMSL2
link.
The MAX96717 driver can handle MAX96717 and MAX96717F variants
with the same "maxim,max96717f" compatible.

Change since v5:
- set the driver compatible back to MAX96717F that can be used as a fallback for MAX96717
Change since v4:
- make the driver compatible with MAX96717 instead of MAX96717F
- Add the device id for the MAX96717
- remove hw_data structure for now, it can be usefull later for handling different serializers e.g max9295
Change since v3:
- Maintainers: align to the new binding path
- Kconfig: better describe the symbol
- store the v4l2_mbus_config_mipi_csi2 structure instead of the full endpoint in the driver private structure
- use MAX96717_PAD_SINK/SOURCE instead of 0/1 for pad intialization
- Removed incorrect call to fwnode_handle_put(priv->sd.fwnode)
- Use unsigned int instead of u8
- Allocate clk name out of the clk struct initialization
- fixed multiline comment
- Removed one unnecessary goto at the end of the probe function
Change since v2:
- Use CCI helpers instead of recoding register access
- add missing bitfield header

You are right, will be fixed in v7.
