Al Cooper 0aa0c12262 phy: phy-brcm-usb-init: DRD mode can cause crash on startup
This is caused by a bug in the BDC core. When the BDC core comes
out of reset and it's not selected, it gets a backup clock. When
the BDC core is selected, it get's the main clock. If HOST mode
is then selected the BDC core has the main clock shut off but
the backup clock is not restored.

The failure scenario and cause are as follows:
- DRD mode is active
- Device mode is selected first in bootloader
- When host mode is now selected, the clock to the BDC is cut off.
- BDC registers are inaccessible and therefore the BDC driver
  crashes upon Linux boot.

The fix is to have the phy driver always force a BDC reset on
startup.

Greg Kroah-Hartman b24413180f License cleanup: add SPDX GPL-2.0 license identifier to files with no license
Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.

By default all files without license information are under the default
license of the kernel, which is GPL version 2.

Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier.  The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.

This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.

How this work was done:

Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
 - file had no licensing information it it.
 - file was a */uapi/* one with no licensing information in it,
 - file was a */uapi/* one with existing licensing information,

Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.

The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne.  Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.

The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed.  Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.

Criteria used to select files for SPDX license identifier tagging was:
 - Files considered eligible had to be source code files.
 - Make and config files were included as candidates if they contained >5
   lines of source
 - File already had some variant of a license header in it (even if <5
   lines).

All documentation files were explicitly excluded.

The following heuristics were used to determine which SPDX license
identifiers to apply.

 - when both scanners couldn't find any license traces, file was
   considered to have no license information in it, and the top level
   COPYING file license applied.

   For non */uapi/* files that summary was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0                                              11139

   and resulted in the first patch in this series.

   If that file was a */uapi/* path one, it was "GPL-2.0 WITH
   Linux-syscall-note" otherwise it was "GPL-2.0".  Results of that was:

   SPDX license identifier                            # files
   ---------------------------------------------------|-------
   GPL-2.0 WITH Linux-syscall-note                        930

   and resulted in the second patch in this series.

 - if a file had some form of licensing information in it, and was one
   of the */uapi/* ones, it was denoted with the Linux-syscall-note if
   any GPL family license was found in the file or had no licensing in
   it (per prior point).  Results summary:

   SPDX license identifier                            # files
   ---------------------------------------------------|------
   GPL-2.0 WITH Linux-syscall-note                       270
   GPL-2.0+ WITH Linux-syscall-note                      169
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause)    21
   ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause)    17
   LGPL-2.1+ WITH Linux-syscall-note                      15
   GPL-1.0+ WITH Linux-syscall-note                       14
   ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause)    5
   LGPL-2.0+ WITH Linux-syscall-note                       4
   LGPL-2.1 WITH Linux-syscall-note                        3
   ((GPL-2.0 WITH Linux-syscall-note) OR MIT)              3
   ((GPL-2.0 WITH Linux-syscall-note) AND MIT)             1

   and that resulted in the third patch in this series.

 - when the two scanners agreed on the detected license(s), that became
   the concluded license(s).

 - when there was disagreement between the two scanners (one detected a
   license but the other didn't, or they both detected different
   licenses) a manual inspection of the file occurred.

 - In most cases a manual inspection of the information in the file
   resulted in a clear resolution of the license that should apply (and
   which scanner probably needed to revisit its heuristics).

 - When it was not immediately clear, the license identifier was
   confirmed with lawyers working with the Linux Foundation.

 - If there was any question as to the appropriate license identifier,
   the file was flagged for further research and to be revisited later
   in time.

In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.

Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights.  The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.

Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.

In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.

Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
 - a full scancode scan run, collecting the matched texts, detected
   license ids and scores
 - reviewing anything where there was a license detected (about 500+
   files) to ensure that the applied SPDX license was correct
 - reviewing anything where there was no detection but the patch license
   was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
   SPDX license was correct

This produced a worksheet with 20 files needing minor correction.  This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.

These .csv files were then reviewed by Greg.  Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected.  This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.)  Finally Greg ran the script using the .csv files to
generate the patches.

Al Cooper 415060b21f phy: usb: phy-brcm-usb: Add ability to force DRD mode to host or device
When the usb phy device mode is set to "drd", the USB port will
switch between device and host modes depending on what's plugged
into the port. Customers have asked for the ability to force
host or device mode from software. This commit adds sysfs
entries to the phy device that allow this. The sysfs for the phy
device can be found at:
/sys/bus/platform/drivers/brcmstb-usb-phy/*.usb-phy

The following sysfs entries were added:
- "dr_mode" (RO) - The current phy "dr_mode" setting.
  It will be set to one of the following values:
  - "host" - host mode
  - "peripheral " - device mode
  - "drd" - switch between device and host mode based on
    installed device
  - "typec-pd" - device/host mode is controller by the USB
    Type-C PD protocol.

If "dr_mode" is "drd"
- "drd_select" (RW) -
  It will be set to one of the following values:
  - "host" - force host mode
  - "device" - force device mode
  - "auto" - allow normal auto selection of host/device based on
    inserted USB device

     shipped in the Android O release, plus some more changes that
     happened since then that are in the Android development trees.
   - coresight updates and fixes
   - mux driver file renames to be a bit "nicer"
   - intel_th driver updates
   - normal set of hyper-v updates and changes
   - small fpga subsystem and driver updates

Greg Kroah-Hartman 9f57ed095f Update extcon for 4.14
Detailed description for this pull request:
 1. Add new 'extcon-usbc-cros-ec.c' driver
 - ChromeOS Embedded Controller extcon driver supports
   the detection of the Display Port (EXTCON_DISP_DP)
   through USB C-type and contol it.
 
 2. Update extcon core
 - Modify the description for both functions and structures
   in order to improve the readability and give the more correct
   guide about the role of functions because there are different
   explanation even if the same arguments.
 
 - Keep the indentation with tab instead of space
 
 - Remove the following deprecated extcon API. The deprecated API
   are exchanged on all of linux tree.
   : extcon_get_cable_state_() -> extcon_get_state()
   : extcon_set_cable_state_() -> extcon_set_state_sync()
 
 3. Include the two immutable branch as following:
 - ib-extcon-mfd-4.14 for the 'extcon-ubsc-cros-ec.c' driver
   because the patches of 'extcon-ubsc-cros-ec.c' touch the MFD directory.
 - ib-extcon-usb-phy-4.14 for removing the deprecated extcon API
   because the usb/phy driver usese the deprecated extcon API.
   So, this immutable branch alters the extcon API and then
   remove them from extcon.
 
 4. Fix minor issue of extcon driver
 - Fix the MHL detection on extcon-max77693.c
 - Convert to using %pOF instead of full_name on extcon.c
 - Add 'const' kerywod for acpi_device_id on extcon-intel-int3496.c

Rafał Miłecki af850e14a7 phy: bcm-ns-usb3: add MDIO driver using proper bus layer
As USB 3.0 PHY is attached to the MDIO bus this module should provide a
MDIO driver and use a proper bus layer. This is a proper (cleaner)
solution which doesn't require code to know this specific MDIO bus
details. It also allows reusing the driver with other MDIO buses.

For now keep platform device support in place. We may consider dropping
it once MDIO bindings gets used "everywhere".
