Upstreaming effort
Free Electrons maintains a number of branches reflecting the in-progress upstream work. For historical reasons, they are based on 4.12. Those branches are available in the public Git repository at https://github.com/MISL-EBU-System-SW/mainline-public. The logic is as follows:
backport-4.12
is based on v4.12, with patches backported from upstream, i.e patches that have already been accepted. This branch is not rebased.devel-4.12/<topic>
are topic branches for in-progress work, not yet merged upstream. Such branches are based onbackport-4.12
(they are exceptions), and are rebased as neededdevel-4.12/all
which is a branch resulting of the merge of all thedevel-4.12/<topic>
branches
The current topic branches are:
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 the improvements in the mvpp2 network driver to support 10G, dynamic PHY reconfiguration and the GoP link interrupts.devel-4.12/dt64
contains all the Device Tree updates. They are regrouped in a single topic branches to avoid conflictsdevel-4.12/dt
contains all the Device Tree updates for ARM32. They are regrouped in a single topic branches to avoid conflictsdevel-4.12/defconfig64
contains the ARM64 defconfig specific patches.devel-4.12/misc
contains various single improvement that were not part of a series of patches.
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-tso devel-4.12/comphy devel-4.12/ppv2-dynamic-phy devel-4.12/misc devel-4.12/dt64 devel-4.12/dt
