Linux 4.0 was released a couple of weeks ago and like previous kernel releases, this version again contains contributions made by Collabora engineers as a part of our current projects.

In total 59 patches were contributed to the 4.0 release. These were for:

  • Fix graphics DP and HDMI display for Exynos DRM.
  • More preparation work to add Atomic Mode Settings support to the Exynos DRM driver.
  • Add support for Power, Lid keys and built-in USB camera to Peach Pi/Pit and Snow Chromebooks.
  • Configure regulators operating modes on suspend for Peach Pi/Pit Chromebooks to reduce power consumption.
  • Add DISP1 power domain and related clocks to have proper display support on Exynos5420 machines.
  • Extend the MMC simple power sequencing provider to support a reference clock and more than one reset GPIO.
  • Fix various regressions in the common clock framework exposed by the per-user clock changes.
  • Fix S3C Real-Time-Clock that was not working on many Exynos SoCs.
  • Fix a bug in the regulator framework that tried to enable regulators that were already enabled.
  • Fix a reboot and poweroff hang on Exynos machines cause by a hang in the samsung serial driver.
  • Various fixes to the Samsung MFC driver.
  • Add support for the Exynos5422 Odroid XU3 board.
  • Enable needed Kconfig symbols on the exynos, omap2plus and multi_v7 defconfigs.
  • Add a devfreq driver for the Tegra Activity Monitor

Following is the complete list of patches merged in this kernel release:
