f0001f5877 dt-bindings: phy: Document cadence Sierra PHY bindings
Add DT binding documentation for Sierra PHY.  The PHY supports
a number of different protocols, including PCIe and USB.

The PHY lanes may be configured as single or multi-lane links.
Each link is treated as a separate sub-node.  For example, if
there are 4 lanes in total the first 2 might be configured as
a multi-lane PCIe link while the other two are single lane
USB links, and in this case there would be 3 sub-nodes.

There are two resets for the PHY block (one for APB register
access, one for the PHY link) and separate resets for each
link.  For multi-lane links, the reset corresponds to the
reset line on the master lane, the resets on other lanes
have no effect.

fc381bb235 drm/panel: Augment the TPO TPG110 bindings
The TPO TPG110 bindings were using the DPI bindings (popular
in the fbdev subsystem) but this misses the finer points
learned in the DRM subsystem.

We need to augment the bindings for proper DRM integration:
the timings are expressed by the hardware, not put into the
device tree. I.e. this hardware is self-describing and can
report the resolutions and timings needed. It should not
be described in the device tree.

Further the device was incorrectly modeled with GPIO lines
instead of an SPI child, even though the device was using
SPI.

No known deployments of the device using device tree
exist, so it should be fine to augment the bindings.

====================
pull-request: can 2018-11-09

this is a pull request of 20 patches for net/master.

First we have a patch by Oliver Hartkopp which changes the raw socket's
raw_sendmsg() to return an error value if the user tries to send a CANFD
frame to a CAN-2.0 device.

The next two patches are by Jimmy Assarsson and fix potential problems
in the kvaser_usb driver.

YueHaibing's patches for the ucan driver fix a compile time warning and
remove a duplicate include.

Eugeniu Rosca patch adds more binding documentation to the rcar_can
driver bindings. The next two patches are by Fabrizio Castro for the
rcar_can driver and fixes a problem in the driver's probe function and
document the r8a774a1 binding.

Lukas Wunner's patch fixes a recpetion problem in hi311x driver by
switching from edge to level triggered interruts.

The next three patches all target the flexcan driver. Pankaj Bansal's
patch unconditionally unlocks the last mailbox used for RX. Alexander
Stein provides a better workaround for a hardware limitation when
sending RTR frames, by using the last mailbox for TX, resulting in fewer
lost frames. The patch by me simplyfies the driver, by making a runtime
value a compile time constant.

The following 4 patches are by me and provide the groundwork for the
next patches by Oleksij Rempel. To avoid code duplication common code in
the common CAN driver infrastructure is factured out and error handling
is cleaned up.

The next 4 patches are by Oleksij Rempel and fix the problem in the
flexcan driver that other processes see TX frames arrive out of order
with ragards to a RX'ed frame (which are send by a different system on
the CAN bus as the result of our TX frame).

7243ec72b9 dt-bindings: phy-qcom-qmp: Fix several mistakes from prior commits
Digging through the "phy-qcom-qmp" showed me many inconsistencies
between the bindings and the reality of the driver.  Let's fix them
all.

* In commit 2d66eab18375 ("dt-bindings: phy: qmp: Add support for QMP
  phy in IPQ8074") we probably should have explicitly listed that
  there are no clocks for this PHY and also added the reset names in
  alphabetical order.  You can see that there are no clocks in the
  driver where "clk_list" is NULL.

* In commit 8587b220f05e ("dt-bindings: phy-qcom-qmp: Update bindings
  for QMP V3 USB PHY") we probably should have listed the resets for
  this new PHY and also removed the "(Optional)" marking for the "cfg"
  reset since PHYs that need "cfg" really do need it.  It's just that
  not all PHYs need it.

* In commit 7f0802074120 ("dt-bindings: phy-qcom-qmp: Update bindings
  for sdm845") we forgot to update one instance of the string
  "qcom,qmp-v3-usb3-phy" to be "qcom,sdm845-qmp-usb3-phy".  Let's fix
  that.  We should also have added "qcom,sdm845-qmp-usb3-uni-phy" to
  the clock-names and reset-names lists.

* In commit 99c7c7364b71 ("dt-bindings: phy-qcom-qmp: Add UFS phy
  compatible string for sdm845") we should have added the set of
  clocks and resets for "qcom,sdm845-qmp-ufs-phy".  These were taken
  from the driver.

* Cleanup the wording for what properties child nodes have to make it
  more obvious which types of PHYs need clocks and resets.  This was
  sorta implicit in the "-names" description but I found myself
  confused.

* As per the code not all "pcie qmp phys" have resets.  Specifically
  note that the "has_lane_rst" property in the driver is false for
  "ipq8074-qmp-pcie-phy".  Thus make it clear exactly which PHYs need
  child nodes with resets.

ab214c4838 dt-bindings: i2c: omap: Add new compatible for AM654 SoCs
AM654 SoCs have same I2C IP as OMAP SoCs. Add new compatible to
handle AM654 SoCs. While at that reformat the existing compatible list
for older SoCs to list one valid compatible per line.

f164d0204b can: hi311x: Use level-triggered interrupt
If the hi3110 shares the SPI bus with another traffic-intensive device
and packets are received in high volume (by a separate machine sending
with "cangen -g 0 -i -x"), reception stops after a few minutes and the
counter in /proc/interrupts stops incrementing.  Bus state is "active".
Bringing the interface down and back up reconvenes the reception.  The
issue is not observed when the hi3110 is the sole device on the SPI bus.

Using a level-triggered interrupt makes the issue go away and lets the
hi3110 successfully receive 2 GByte over the course of 5 days while a
ks8851 Ethernet chip on the same SPI bus handles 6 GByte of traffic.

Unfortunately the hi3110 datasheet is mum on the trigger type.  The pin
description on page 3 only specifies the polarity (active high):

Commit f174e49e4906 (cpufreq: remove unused arm_big_little_dt driver)
removed the driver supporting this binding, but the binding was left
unnoticed, so let's get rid of it now.

7.1.5 Response to Hard Resets
Device operation during and after a Hard Reset is defined as follows:
Self-powered devices Should Not disconnect from USB during a Hard Reset
(see Section 9.1.2).
Bus powered devices will disconnect from USB during a Hard Reset due to the
loss of their power source.

Therefore it is necessary to know whether the port belongs to
a device which is self powered or bus powered. This change
adds "self-powered" flag to the connector class which present indicates
that the port belongs to a device that is self powered. Else it is
bus powered usb device.
