Upstreaming effort

Free Electrons maintains a number of branches reflecting the in-progress upstream work. They are based on 4.14. Those branches are available in the public Git repository at https://github.com/MISL-EBU-System-SW/mainline-public. The logic is as follows:

  • devel-4.14/<topic> are topic branches for work in progress, not yet merged upstream. Such branches are based on backport-4.14 (there are exceptions), and are rebased as needed
  • devel-4.14/all which is a branch resulting of the merge of all the devel-4.14/<topic> branches

These branches are:

  • backport-4.14 is based on v4.14, with patches backported from upstream, i.e patches that had already been accepted. This branch is not rebased.
  • devel-4.14/comphy contains fixes and improvements for the comphy.
  • devel-4.14/ppv2 contains fixes and improvements in the mvpp2 network driver.
  • devel-4.14/crypto contains fixes and optimizations for the Inside Secure SafeXel cryptographic engine which can be found on Marvell 7k/8k and 3720 SoCs.
  • devel-4.14/nand contains the reworked NAND framework as it has been sent in the RFCv2 and the reworked NAND controller driver (works with 32-bits platforms).
  • devel-4.14/pcie contains improvements for compatibility with PCI devices with aardvark (PCIE host controller on Armada 3700).
  • devel-4.14/cpufreq contains support for CPU frequency scaling on Armada 3700.
  • devel-4.14/thermal contains support for thermal management on Armada SoCs (370,375,XP,38x,7K,8K).
  • devel-4.14/dt contains all the ARM32 Device Tree updates. They are regrouped in a single topic branches to avoid conflicts.
  • devel-4.14/dt64 contains all the ARM64 Device Tree updates. They are regrouped in a single topic branches to avoid conflicts.
  • devel-4.14/defconfig64 contains the ARM64 defconfig specific patches.
  • devel-4.14/custom-defconfig64 contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based on devel-4.14/defconfig64.

Commands used to generate the devel-4.14/all branch (so that topic branches are always merged in the same order) :

git reset --hard backport-4.14
git merge devel-4.14/comphy devel-4.14/ppv2 devel-4.14/crypto devel-4.14/nand devel-4.14/uart devel-4.14/pcie devel-4.14/cpufreq devel-4.14/thermal devel-4.12/dt devel-4.12/dt64 devel-4.12/defconfig64 devel-4.12/custom-defconfig64

Former 4.12 branches

The 4.12 based branches are no more updated and obsolete, but there are currently as is for those who still need it. For the record,

These branches are:

  • backport-4.12 is based on v4.12, with patches backported from upstream, i.e patches that had already been accepted. 'This branch is not rebased.
  • devel-4.12/fixes contains various fixes not merged yet in mainline (and that are not device tree fix as all the device tree related patches are in devel-4.12/dt or devel-4.12/dt64)
  • devel-4.12/ppv2 contains improvements in the mvpp2 network driver.
  • devel-4.12/dt64 contains all the Device Tree updates. They are regrouped in a single topic branches to avoid conflicts
  • devel-4.12/dt contains all the Device Tree updates for ARM32. They are regrouped in a single topic branches to avoid conflicts
  • devel-4.12/defconfig64 contains the ARM64 defconfig specific patches.
  • devel-4.12/custom-defconfig64 contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based on devel-4.12/defconfig64.
  • devel-4.12/misc contains various single improvement that were not part of a series of patches.
  • devel-4.12/xenon contains all Xenon (SD and eMMC controller) fixes and improvement.

Commands used to generate the devel-4.12/all branch (so that topic branches are always merged in the same order) :

git reset --hard backport-4.12
git merge devel-4.12/fixes devel-4.12/ppv2 devel-4.12/misc devel-4.12/xenon devel-4.12/dt64 devel-4.12/dt devel-4.12/defconfig64 devel-4.12/custom-defconfig64
