[PATCH v3 1/2] media: staging: rkisp1: remove mbus field from rkisp1_sensor_async

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

'struct v4l2_mbus_config' is a legacy struct that should not be used
in new drivers. So replace it with the fields:

enum v4l2_mbus_type mbus_type;
unsigned int mbus_flags;

Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@xxxxxxxxxxxxx>
---
no changes since v1.

changes since v2:
- rename the field 'parallel_bus_flags' to 'mbus_flags'
and set it to vep->bus.mipi_csi2.flags instead of 0.
change the commit log accordingly.
