Update extcon for 4.15

Detailed description for this pull request:
1. 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.
- include/linux/extcon-provider.h includes API for the provider device driver.
- include/linux/extcon.h includes the API for the consumer device driver.

2. Support the SmartDock accessory on extcon-max77843.c device driver
- Support the SmartDock accessory which detects following connectors
 at the same time.
 : USB host throught USB hub for mouse, keyboard and so on.
 : MHL connector for video output.
 : Charger connector for battery charging.
- It tested with Unitek Y-2165 MHL+OTG Hub Smart Phone Dock.

3. Fix the minor issue of extcon driver
- Delete the unneeded initialization in extcon-max14577.
- Make extcon_info static const in order to fix the warning.

extcon: Split out extcon header file for consumer and provider device

2017-10-23T05:07:58+00:00

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

phy: sun4i-usb: Support A83T USB PHYs

2017-08-22T04:41:18+00:00

The A83T has 3 USB PHYs, 1 for OTG, 1 for standard USB, 1 for USB HSIC.
The phy initialization procedure is very different from other SoCs, but
the PMU bits are the same, with additional bits for HSIC.

phy: sun4i-usb: Support secondary clock for HSIC PHY

2017-08-22T04:41:17+00:00

On the Allwinner A83T SoC, the last USB PHY is an HSIC PHY. It requires
two clocks instead of one.

On all Allwinner SoCs that share the common USB PHY design supported by
the phy-sun4i-usb driver, the first PHY is always tied to OTG, and there
is at most one HSIC PHY, typically the last.

In this patch we take advantage of these known constraints and store an
index in the compatible-string-related config structure describing which
PHY is HSIC, needing the extra hsic_12M clock.

phy: allwinner: phy-sun4i-usb: Add log when probing

2017-07-21T07:36:30+00:00

When phy-sun4i-usb's probing fails, it does not print the reason in
kernel log, forcing the developer to edit this driver to add info logs.
This commit makes the kernel print the reason of phy-sun4i-usb's probing
failure or a success message.

phy: Group vendor specific phy drivers

2017-06-01T09:58:33+00:00

Adding vendor specific directories in phy to group
phy drivers under their respective vendor umbrella.

Also updated the MAINTAINERS file to reflect the correct
directory structure for phy drivers.
