Upstreaming effort
Free Electrons maintains a number of branches reflecting the in-progress upstream work. They are based on the current 4.14-rc. 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 in-progress work, not yet merged upstream. Such branches are based on the current 4.14-rc (they are exceptions), and are rebased as neededdevel-4.14/all
which is a branch resulting of the merge of all thedevel-4.14/<topic>
branches
These branches are:
devel-4.14/comphy
adds support for the comphy.devel-4.14/ppv2
contains improvements in the mvpp2 network driver.devel-4.14/dt64
contains all the Device Tree updates. They are regrouped in a single topic branches to avoid conflictsdevel-4.14/defconfig64
contains the ARM64 defconfig specific patchesdevel-4.14/custom-defconfig64
contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based ondevel-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 v4.14-rc2 git merge devel-4.14/comphy devel-4.14/ppv2 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, 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 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/custom-defconfig64
contains out of tree patches to enable Marvell EBU specific drivers in the ARM64 defconfig. Based ondevel-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
