Generic helpers for Mediatek SoCs ISP drivers. Mediatek
|
|
SoCs ISP drivers have similar image handling flow. For
|
|
example, Mediatek's ISP IPs may accept multiple input
|
|
buffers of a frame and generate multiple output buffers
|
|
of different format, size and effect. The helpers
|
|
provide the functions to create the common flow.
|
|
|
|
This feature will be removed in the upstream version
|
|
of Mediatek SoCs ISP drivers. It added some
|
|
abstraction implementing V4L2 and VB2 ops using
|
|
MTK-specific ops, which is not a discouraged pattern
|
|
of V4L2 drivers.
|
|
|
|
Choose y if you have drivers using the common utilities.
