[PATCH 09/10] media: vpif: use a configurable i2c_adapter_id for vpif display

Bartosz Golaszewski
2017-02-07T16:42:10Z

The vpif display driver uses a static i2c adapter ID of 1 but on the
da850-evm board in DT boot mode the i2c adapter ID is actually 0.

Make the adapter ID configurable like it already is for vpif capture.
