Here is the big set of USB and PHY driver updates for 4.15-rc1. There is the usual amount of gadget and xhci driver updates, along with phy and chipidea enhancements. There's also a lot of SPDX tags and license boilerplate cleanups as well, which provide some churn in the diffstat. Other major thing is the typec code that moved out of staging and into the "real" part of the drivers/usb/ tree, which was nice to see happen. All of these have been in linux-next with no reported issues for a while.

/**
|
|
* struct extcon_dev - An extcon device represents one external connector.
|
|
* @name: The name of this extcon device. Parent device name is
|
|
* used if NULL.
|
|
* @supported_cable: Array of supported cable names ending with EXTCON_NONE.
|
|
* If supported_cable is NULL, cable name related APIs
|
|
* are disabled.
|
|
* @mutually_exclusive: Array of mutually exclusive set of cables that cannot
|
|
* be attached simultaneously. The array should be
|
|
* ending with NULL or be NULL (no mutually exclusive
|
|
* cables). For example, if it is { 0x7, 0x30, 0}, then,
|
|
* {0, 1}, {0, 1, 2}, {0, 2}, {1, 2}, or {4, 5} cannot
|
|
* be attached simulataneously. {0x7, 0} is equivalent to
|
|
* {0x3, 0x6, 0x5, 0}. If it is {0xFFFFFFFF, 0}, there
|
|
* can be no simultaneous connections.
|
|
* @dev: Device of this extcon.
|
|
* @state: Attach/detach state of this extcon. Do not provide at
|
|
* register-time.
|
|
* @nh_all: Notifier for the state change events for all supported
|
|
* external connectors from this extcon.
|
|
* @nh: Notifier for the state change events from this extcon
|
|
* @entry: To support list of extcon devices so that users can
|
|
* search for extcon devices based on the extcon name.
|
|
* @lock:
|
|
* @max_supported: Internal value to store the number of cables.
|
|
* @extcon_dev_type: Device_type struct to provide attribute_groups
|
|
* customized for each extcon device.
|
|
* @cables: Sysfs subdirectories. Each represents one cable.
|
|
*
|
|
* In most cases, users only need to provide "User initializing data" of
|
|
* this struct when registering an extcon. In some exceptional cases,
|
|
* optional callbacks may be needed. However, the values in "internal data"
|
|
* are overwritten by register function.
