Linux Kernel 4.7 was released this week with a total of 36 contributions from five Collabora engineers. It includes the first contributions from Helen as Collaboran and the first ever contributions on the kernel from Robert Foss. Here are some of the highlights of the work Collabora have done on Linux Kernel 4.7.

Enric added support for the Analogix anx78xx DRM Bridge and fixed two SD Card related issues on OMAP igep00x0: fix remove/insert detection and enable support to read the write-protect pin.

Gustavo de-staged the sync_file framework (Android Sync framework) that will be used to add explicit fencing support to the graphics pipeline and started a work to clean up usage of legacy vblank helpers.

Helen Koike created a separated module for the V4L2 Test Pattern Generator and fixed return errors on the pipeline validation code while Robert Foss improved the DRM documentation and fixed drm/vc4 (Raspberry Pi) when there is already a pending update when calling atomic_commit.

Tomeu fixed two Rockchip issues while working on the intel-gpu-tools support for other platforms.
