Florian Fainelli 6ec248fed5 phy: brcm-sata: Prepare for doing more tuning
Split the functional code in brcm_stb_sata_init() to a separate function
that actually does configure spread spectrum: brcm_stb_sata_ssc_init()
and make that function return void, since that function cannot fail.

Chanwoo Choi 176aa36012 extcon: Split out extcon header file for consumer and provider device
The extcon has two type of extcon devices as following.
- 'extcon provider deivce' adds new extcon device and detect the
   state/properties of external connector. Also, it notifies the
   state/properties to the extcon consumer device.
- 'extcon consumer device' gets the change state/properties
   from extcon provider device.
Prior to that, include/linux/extcon.h contains all exported API for
both provider and consumer device driver. To clarify the meaning of
header file and to remove the wrong use-case on consumer device,
this patch separates into extcon.h and extcon-provider.h.

[Description for include/linux/{extcon.h|extcon-provider.h}]
- extcon.h includes the extcon API and data structure for extcon consumer
  device driver. This header file contains the following APIs:
  : Register/unregister the notifier to catch the change of extcon device
  : Get the extcon device instance
  : Get the extcon device name
  : Get the state of each external connector
  : Get the property value of each external connector
  : Get the property capability of each external connector

- extcon-provider.h includes the extcon API and data structure for extcon
  provider device driver. This header file contains the following APIs:
  : Include 'include/linux/extcon.h'
  : Allocate the memory for extcon device instance
  : Register/unregister extcon device
  : Set the state of each external connector
  : Set the property value of each external connector
  : Set the property capability of each external connector

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

Linus Torvalds bafb0762cb Char/Misc drivers for 4.14-rc1
Here is the big char/misc driver update for 4.14-rc1.
 
 Lots of different stuff in here, it's been an active development cycle
 for some reason.  Highlights are:
   - updated binder driver, this brings binder up to date with what
     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
   - lots of const code changes all over the driver trees
   - extcon driver updates
   - fmc driver subsystem upadates
   - w1 subsystem minor reworks and new features and drivers added
   - spmi driver updates
 
 Plus a smattering of other minor driver updates and fixes.
 
 All of these have been in linux-next with no reported issues for a
 while.

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".
