Subject: [PATCH 00/10] Qualcomm 8x16 Camera Subsystem driver
This patchset adds basic support for the Qualcomm Camera Subsystem found
on Qualcomm MSM8916 and APQ8016 processors.
The driver implements V4L2, Media controller and V4L2 subdev interfaces.
Camera sensor using V4L2 subdev interface in the kernel is supported.
The driver is implemented using as a reference the Qualcomm Camera
Subsystem driver for Android as found in Code Aurora [1].
The driver supports raw dump of the input data to memory. ISP processing
is not supported.
The driver is tested on Dragonboard 410C (APQ8016) with one and two
OV5645 camera sensors. media-ctl [2] and yavta [3] applications were
used for testing. Also Gstreamer 1.4.4 with v4l2src plugin is supported.
More information is present in the document added by the third patch.
The patchset depends on:
v4l: Add packed Bayer raw12 pixel formats [4]
media: venus: enable building of Venus video codec driver [5]
V4L2 compliance test result:
root@...aro-alip:~/v4l-utils/utils/v4l2-compliance# ./v4l2-compliance -s -d /dev/video0
