99e45e29b6 New boards are the Radxa Rock Pi N10 using the VMARC SOM and Dalang
carrier board, separate versions for the two rockpro64 hardware revisions
 which switched a pin between revisions. The rockpro64 also got
 bluetooth support now.
 
 The px30 got a lot of attention with dsi, gpu and thermal support.
 Similarly the rk3399-roc-pc board also got attention with mtd flash,
 sdr104 mode, hdmi sound, gpu and a lot of other smaller improvements.
 
 Other than that there is a new gpu-cooling device for rk3399 a cpu
 idle-state for rk3328 and more small improvements across a number
 of boards.

Jacob Keller says:

====================
devlink documentation refactor

This series updates the devlink documentation, with a few primary goals

 * move all of the devlink documentation into a dedicated subfolder
 * convert that documentation to the reStructuredText format
 * merge driver-specific documentations into a single file per driver
 * add missing documentation, including per-driver and devlink generally

For each driver, I took the time to review the code and add further
documentation on the various features it currently supports. Additionally, I
added new documentation files for some of the features such as
devlink-dpipe, devlink-resource, and devlink-regions.

Note for the region snapshot triggering, I kept that as a separate patch as
that is based on work that has not yet been merged to net-next, and may
change.

I also improved the existing documentation for devlink-info and
devlink-param by adding a bit more of an introduction when converting it to
the rst format.

6c39e015f8 devlink: convert driver-specific files to reStructuredText
Several drivers document what parameters they support in
a devlink-params-*.txt file. This file is supposed to contain both the
list of generic parameters implemented by the driver, as well as a list
of driver-specific parameters and their descriptions.

It would also be good if the driver documentation included other
driver-specific implementations, such as info versions, devlink
regions, and so forth.

Convert all of these documentation files to reStructuredText, and rename
them to just the driver name. Future changes will include other
driver-specific implementations. Each file will contain a table for the
generic parameters implemented, as well as a separate table for the
driver-specific parameters.

Future sections such as for devlink info versions will be added to these
files. This avoids creating additional devlink-<feature>-<driver> files
for each devlink feature, reducing clutter in the documentation folder.

4c582234ab devlink: Wait longer before warning about unset port type
The commit cited below causes devlink to emit a warning if a type was
not set on a devlink port for longer than 30 seconds to "prevent
misbehavior of drivers". This proved to be problematic when
unregistering the backing netdev. The flow is always:

devlink_port_type_clear()	// schedules the warning
unregister_netdev()		// blocking
devlink_port_unregister()	// cancels the warning

The call to unregister_netdev() can block for long periods of time for
various reasons: RTNL lock is contended, large amounts of configuration
to unroll following dismantle of the netdev, etc. This results in
devlink emitting a warning despite the driver behaving correctly.

In emulated environments (of future hardware) which are usually very
slow, the warning can also be emitted during port creation as more than
30 seconds can pass between the time the devlink port is registered and
when its type is set.

In addition, syzbot has hit this warning [1] 1974 times since 07/11/19
without being able to produce a reproducer. Probably because
reproduction depends on the load or other bugs (e.g., RTNL not being
released).

To prevent bogus warnings, increase the timeout to 1 hour.

In preperation of factoring out the PHY configuration to a separate

- avoids accessing rtl8169_private internals by passing the phy_device

- renames rtl_hw_phy_config to r8169_hw_phy_config to avoid namespace
  clashes with other drivers for Realtek hardware

platform/chrome: wilco_ec: Fix keyboard backlight probing

the keyboard backlight on the absence of a keyboard backlight module.
This change allows the EC driver to continue loading even if the
backlight module is not present.
