imx412 and imx577 return the same chip-id when interrogated via i2c. I've confirmed this myself by Sakari suggested we should add a new compat which should be reflected in the name of the media entity https://patchwork.kernel.org/project/linux-media/patch/20220607134057.2427663-3-bryan.odonoghue@xxxxxxxxxx/#24894500 Set up the .data parameter of of_device_id to pass a string which we use to set the media entity name. Once done we can add in imx577 as a compatible chips with the media names reflecting the directed compat string.
