8e84f8aa53 usb: ehci-platform: use reset array API
Generic drivers like this need to control arbitrary number of reset
lines.  Instead of hard-coding the maximum number of resets, use the
reset array API.  It can manage a bunch of resets behind the scene.

69a0c69aab usb: usb251xb: Use GPIO descriptor consumer interface
The driver used to be developed with legacy GPIO API support. It's
better to use descriptor-based interface for several reasons. First
of all the legacy API doesn't support the ACTIVE_LOW/HIGH flag of dts
nodes, which is essential since different hardware may have different
GPIOs connectivity including the logical value inversion. Secondly,
by requesting the reset GPIO descriptor the driver prevent the other
applications from changing its value. And last but not least the
legacy GPIO interface should be avoided in the new code due to it
obsolescence.

287c2bb6e1 usb: usb251xb: Fix property_u32 NULL pointer dereference
The methods like of_property_read_u32 utilizing the specified
pointer permit only the pointer to a preallocated u32 storage as the
third argument. As a result the driver crashes on NULL pointer
dereference in case if "oc-delay-us" or "power-on-time-ms" declared
in dts file.

2818e13ae1 usb: usb251xb: Add USB2517 LED settings
USB2517 supports two LED modes: USB mode and speed (default) indication

Since USB251xb hubs doesn't support LEDs settings, we need to ignore

dd99d106de usb: usb251xb: Add battery enable setting flag
Battery charging settings are supported by USB251xb hubs only.
USB2517i isn't one of them. So we need to reflect it within the
device-specific data structure. The driver doesn't support dts
property changing this setting, but instead defaults it with zero.
So the flag isn't used anywhere in the driver, but still can be helpful
in future, when necessity of the corresponding dts setting arises.

USB electrical signaling drive strength boost bit is also supported

USB251xb as well as USB2517 datasheet states, that all these
hubs differ by number of ports declared as the last digit in the

Such setting must be reflected in the device specific data

it doesn't get out of available ports.

32bf9fd50f usb-storage: make use of srb local variable
Commit 8b52291a07 ("usb-storage: fix deadlock involving host lock
and scsi_done") added a local variable to usb_stor_control_thread() in
the usb-storage driver.  This local variable holds the value of
us->srb, for use after the host lock has been released.

But as long as we have the value in a local variable, we may as well
use it instead of dereferencing the us pointer all over the place.
This patch makes no functional change; it just makes the code a little
shorter and a little neater.

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.
