df68734101 dt-bindings: phy: Move the Cadence D-PHY bindings
The Cadence D-PHY bindings was defined as part of the DSI block so far.
However, since it's now going to be a separate driver, we need to move the
binding to a file of its own.

6362f0a68d dt-bindings: phy: mvebu-comphy: extend the file to describe a3700 bindings
Current file describe COMPHY bindings for the IP available on the
CP110 of Armada 7k/8k. Bindings are very close (and serve the same
purpose) as the new Armada 3700 COMPHY driver so update this file to
describe both. Also add an example of how to use this second
compatible (same as for the ESPRESSObin).

While doing so, enhance a bit the file by adding upper case where
needed.

d21aafe9a4 dt-bindings: phy-qcom-qmp: Move #clock-cells to child
The phy-qcom-qmp bindings specified #clock-cells as 1. This was never used
because of_clk_add_provider() was never called, so there was no way anybody
could reference these clocks from DT. Furthermore, even if they could be
accessed, the bindings never specified what should go in that additional
cell.

Fix these incomplete and broken bindings. Move the #clock-cells into the
child node, since that is the actual clock provider, and not all
instances of qcom-qmp-phy are clock providers. Also set #clock-cells to
zero, since there's nothing to pass to it.

2517d09b39 dt-bindings: phy-qcom-qmp: Fix register underspecification
Add register regions for the second lane of dual-lane nodes.
This additional specification is needed so that the driver can stop
reaching beyond the tx and rx register allocations to get at the
second lane registers in a dual-lane PHY.

While in there, document #clock-cells as optional for PHYs that don't
provide a pipe clock. Also, document the pcs_misc register region, which
was being quietly supplied and used.

cb96a69072 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.

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 2d66eab183 ("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 8587b220f0 ("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 7f08020741 ("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 99c7c7364b ("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.

 - Work to get rid of direct accesses to struct device_node name and
   type pointers in preparation for removing them. New helpers for
   parsing DT cpu nodes and conversions to use the helpers. printk
   conversions to %pOFn for printing DT node names. Most went thru
   subystem trees, so this is the remainder.
 
 - Fixes to DT child node lookups to actually be restricted to child
   nodes instead of treewide.
 
 - Refactoring of dtb targets out of arch code. This makes the support
   more uniform and enables building all dtbs on c6x, microblaze, and
   powerpc.
 
 - Various DT binding updates for Renesas r8a7744 SoC
 
 - Vendor prefixes for Facebook, OLPC
 
 - Restructuring of some ARM binding docs moving some peripheral bindings
   out of board/SoC binding files
 
 - New "secure-chosen" binding for secure world settings on ARM
 
 - Dual licensing of 2 DT IRQ binding headers

After the commit 8b1087fa3a ("phy: qcom-qmp: Fix dts bindings to
reflect reality") landed there was some review feedback that 'reg'
should have been documented differently.  Fix it as per review
feedback.

As per that feedback:
- Subject should have been 'dt-bindings: phy:' which this patch now
  has.
- We should leave no ambiguity in the ordering of 'reg' ranges even if
  'reg-names' are also specified.
- Normally using reg-names is discouraged unless there's a strong
  reason it's needed (like if there are optional ranges).  In this
  case reg-names wasn't needed but the driver already landed relying
  on reg-names so we'll just document it and move on.

5695d5d197 USB/PHY patches for 4.19-rc1
Here is the big USB and phy driver patch set for 4.19-rc1.
 
 Nothing huge but there was a lot of work that happened this development
 cycle:
 	- lots of type-c work, with drivers graduating out of staging,
 	  and displayport support being added.
 	- new PHY drivers
 	- the normal collection of gadget driver updates and fixes
 	- code churn to work on the urb handling path, using irqsave()
 	  everywhere in anticipation of making this codepath a lot
 	  simpler in the future.
 	- usbserial driver fixes and reworks
 	- other misc changes
 
 Full details are in the shortlog.
 
 All of these have been in linux-next with no reported issues for a
 while.

MIPS: ath79: Fix the USB PHY reset names
The binding for the USB PHY went thru before the driver. However the
new version of the driver now use the PHY core support for reset, and
this expect the reset to be named "phy". So remove the "usb-" prefix

   two new machines based on its older siblings: the H5 based OrangePi
   Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
   we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
   Zero development board (based on H2).
 
 - NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
   development board and p2888 CPU module.
 
 - The Nuvoton npcm750 is a BMC that was newly added, for now we only
   support running on the evaluation board.
 
 - STmicroelectronics stm32 gains support for the stm32mp157c and two
   evaluation boards.
 
 - The Toradex Colibri board family grows a few members based on the
   i.MX6ULL variant.
 
 - The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
   family of chips.
 
 - The Phytec phyBOARD Mira is a family of industrial boards based on
   i.MX6. For now, four models get added.
 
 - TI am335x based PDU-001 is an industrial embedded machine used for
   traffic monitoring
 
 - The Aspeed platform now supports running on the BMC on the Qualcomm
   Centriq 2400 server

The extcon property is used to detect the cable-state but some boards

So the extcon property is not really a required property, move it to be

5d1ebbda03 phy: mapphone-mdm6600: Add USB PHY driver for MDM6600 on Droid 4
Let's add support for the GPIO controlled USB PHY on the MDM6600 modem.
It is used on some Motorola Mapphone series of phones and tablets such
as Droid 4.

The MDM6600 is hardwired to the first OHCI port in the Droid 4 case, and
is controlled by several GPIOs. The USB PHY is integrated into the MDM6600
device it seems. We know this as we get L3 errors from omap-usb-host if
trying to use the PHY before MDM6600 is configured.

The GPIOs controlling MDM6600 are used to power device on and off, to
configure the USB start-up mode (normal mode versus USB flashing), and
they also tell the state of the MDM6600 device.

The two start-up mode GPIOs are dual-purposed and used for out of band
(OOB) wake-up for USB and TS 27.010 serial mux. But we need to configure
the USB start-up mode first to get MDM6600 booted in the right mode to
be usable in the first place.

Note that the Motorola Mapphone Linux kernel tree has a "radio-ctrl"
driver for modems. But it really does not control the radio at all, it
just controls the modem power and start-up mode for USB. So I came to
the conclusion that we're better off having this done in the USB PHY
driver. For adding support for USB flashing mode, we can later on add
a kernel module option for flash_mode=1 or something similar.

Also note that currently there is no PM runtime support for the OHCI
on omap variant SoCs. So for low(er) power idle states, currenty both
ohci-platform and phy-mapphone-mdm6600 must be unloaded or unbound.

For reference here is what I measured for total power consumption on
an idle Droid 4 with and without USB related MDM6600 modules:

idle lcd off	phy-mapphone-mdm6600	ohci-platform
153mW		284mW			344mW

So it seems that MDM6600 is currently not yet idling even with it's
radio turned off, but that's something that is beyond the control of
this USB PHY driver. This patch does get us to the point where modem
data and GPS are usable with libqmi and ModemManager for example.
Voice calls need more audio driver work.

Amlogic Meson GXL SoCs use a dwc3 controller with two (GXM - a variant

peripheral (also called "device") mode.
While the dwc3 controller has no USB3 port enabled we still need the
USB3 PHY to be initialized. Otherwise high-speed USB transfers (for
example with a USB flash drive) may time out (most often seen on boards
with mainline u-boot, where the bootloader does not initialize the USB3
