[libcamera-devel] [PATCH 2/2] android: Update Android headers
Laurent Pinchart
laurent.pinchart at ideasonboard.com
Thu May 27 03:01:49 CEST 2021
Import the latest version of the Android headers from Chrome OS (commit
a30340e77ec8 ("camera: Uprev Android camera headers")). This brings in
the Camera HAL v3.5 support.
The headers are imported verbatim, except for the addition of the SPDX
headers.
