Linux 3.19 was released last week and this version again contains contributions made by Collabora engineers as a part of our current projects.

In total 60 patches were contributed to the 3.19 release. These were for:

• Work in the Intel i915 DRM driver to support atomic plane updates.
• Fixes and removal of unnecessary layers in the Exynos DRM driver as a preparation to add atomic mode settings support.
• Add support to the regulator framework to define regulators initial and suspend operating modes.
• Changes to the max77802 regulator driver to support regulator operating modes changes.
• Fix the Real-Time-Clock in the Snow, Peach Pit and Pi Chromebooks.
• Enable kernel config options to have display panel working on Exynos boards.
• Allow the regulator drivers to be enabled and disabled when Exynos system enters and leave suspend states.
• Many cleanup and fixes to the common clock framework and clock drivers as a preparation for the per-user clock API change.
