From 1ac84feab8ace4b147023e36867dadb6e6e9a082 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 27 May 2021 03:46:34 +0300 Subject: android: Update Android headers 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.
