Here is the big staging and IIO driver update for 4.18-rc1.
It was delayed as I wanted to make sure the final driver deletions did
not cause any major merge issues, and all now looks good.
There are a lot of patches here, just over 1000. The diffstat summary
shows the major changes here:
1007 files changed, 16828 insertions(+), 227770 deletions(-)
Because of this, we might be close to shrinking the overall kernel
source code size for two releases in a row.
There was loads of work in this release cycle, primarily:
- tons of ks7010 driver cleanups
- lots of mt7621 driver fixes and cleanups
- most driver cleanups
- wilc1000 fixes and cleanups
- lots and lots of IIO driver cleanups and new additions
- debugfs cleanups for all staging drivers
- lots of other staging driver cleanups and fixes, the shortlog
has the full details.
but the big user-visable things here are the removal of 3 chunks of
code:
- ncpfs and ipx were removed on schedule, no one has cared about
this code since it moved to staging last year, and if it needs
to come back, it can be reverted.
- lustre file system is removed. I've ranted at the lustre
developers about once a year for the past 5 years, with no
real forward progress at all to clean things up and get the
code into the "real" part of the kernel. Given that the
lustre developers continue to work on an external tree and try
to port those changes to the in-kernel tree every once in a
while, this whole thing really really is not working out at
all. So I'm deleting it so that the developers can spend the
time working in their out-of-tree location and get things
cleaned up properly to get merged into the tree correctly at a
later date.
Because of these file removals, you will have merge issues on some of
these files (2 in the ipx code, 1 in the ncpfs code, and 1 in the
atomisp driver). Just delete those files, it's a simple merge :)
All of this has been in linux-next for a while with no reported
problems.

DPAA2 Ethernet Switch driver

Features
Supported Platforms
===================
This driver provides networking support for Freescale LS2085A, LS2088A
DPAA2 SoCs.
Architecture Overview
=====================
The Ethernet Switch in the DPAA2 architecture consists of several hardware
resources that provide the functionality. These are allocated and
configured via the Management Complex (MC) portals. MC abstracts most of
these resources as DPAA2 objects and exposes ABIs through which they can
be configured and controlled.
For a more detailed description of the DPAA2 architecture and its object
abstractions see:
drivers/staging/fsl-mc/README.txt
The Ethernet Switch is built on top of a Datapath Switch (DPSW) object.

Driver uses the switch device driver model and exposes each switch port as
a network interface, which can be included in a bridge. Traffic switched
between ports is offloaded into the hardware. Exposed network interfaces
are not used for I/O, they are used just for configuration. This
limitation is going to be addressed in the future.
The DPSW can have ports connected to DPNIs or to PHYs via DPMACs.

Creating an Ethernet Switch
===========================
A device is created for the switch objects probed on the MC bus. Each DPSW
has a number of properties which determine the configuration options and
associated hardware resources.
A DPSW object (and the other DPAA2 objects needed for a DPAA2 switch) can
be added to a container on the MC bus in one of two ways: statically,
through a Datapath Layout Binary file (DPL) that is parsed by MC at boot
time; or created dynamically at runtime, via the DPAA2 objects APIs.
Features
========
Driver configures DPSW to perform hardware switching offload of
unicast/multicast/broadcast (VLAN tagged or untagged) traffic between its
ports.
It allows configuration of hardware learning, flooding, multicast groups,
port VLAN configuration and STP state.
Static entries can be added/removed from the FDB.
Hardware statistics for each port are provided through ethtool -S option.
