Subject: [PATCH]_mbus_config
|
|
ops
|
|
|
|
Upstream https://patchwork.linuxtv.org/patch/64674/
|
|
|
|
Use the new get_mbus_config and set_mbus_config pad operations in place
|
|
of the video operations currently in use.
|
|
|
|
Compared to other drivers where the same conversion has been performed,
|
|
ov6650 proved to be a bit more tricky, as the existing g_mbus_config
|
|
implementation did not report the currently applied configuration but
|
|
the set of all possible configuration options.
|
|
|
|
Adapt the driver to support the semantic of the two newly introduced
|
|
operations:
|
|
- get_mbus_config reports the current media bus configuration
|
|
- set_mbus_config applies only changes explicitly requested and updates
|
|
the provided cfg parameter to report what has actually been applied to
|
|
the hardware.
|
|
|
|
Compile-tested only.
