Li Jun 1bfcaa5700 extcon: ptn5150: Add usb role class support
Some usb controller drivers may not support extcon but use
usb role class as it's the preferred approach, so to support
usb dual role switch with usb role class, add usb role class
consumer support.

Markuss Broks a84df1c7dd extcon: sm5502: Add support for SM5703
SM5703 is another MFD from Silicon Mitus which has a very similar MUIC
unit to the one in SM5502. The only difference I've noticed is slightly different
configuration only enables the interrupts which are exactly the same as on SM5502.
If we make use of different interrupts in the future, this can be improved by having
a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter)
is working properly.

Hans de Goede b7fa2cd357 extcon: intel-cht-wc: Support devs with Micro-B / USB-2 only Type-C connectors
So far the extcon-intel-cht-wc code has only been tested on devices with
a Type-C connector with USB-PD, USB3 (superspeed) and DP-altmode support
through a FUSB302 Type-C controller.

Some devices with the intel-cht-wc PMIC however come with an USB-micro-B
connector, or an USB-2 only Type-C connector without USB-PD.

Which device-model we are running on can be identified with the new
cht_wc_model intel_soc_pmic field. On models without a Type-C controller
the extcon code must control the Vbus 5V boost converter and the USB role
switch depending on the detected cable-type.

Fabio Aiuto 968bd3f038 extcon: extcon-axp288: Use P-Unit semaphore lock for register accesses
use low level P-Unit semaphore lock for axp288 register
accesses directly and for more than one access a time,
to reduce the number of times this semaphore is locked
and released which is an expensive operation.

i2c-bus to the XPower is shared between the kernel and the
SoCs P-Unit. The P-Unit has a semaphore wich the kernel must
lock for axp288 register accesses. When the P-Unit semaphore
is locked CPU and GPU power states cannot change or the system
will freeze.

The P-Unit semaphore lock is already managed inside the regmap
access logic, but for each access the semaphore is locked and
released. So use directly iosf_mbi_(un)block_punit_i2c_access(),
we are safe in doing so because nested calls to the same
semaphore are turned to nops.

Stephan Gerhold d97c0ff5a1 extcon: sm5502: Add support for SM5504
SM5504 is another MUIC from Silicon Mitus that is fairly similar
to SM5502. They seem to use the same register set, but:

  - SM5504 has some additional bits in SM5502_REG_CONTROL
  - SM5504 has a quite different set of interrupts
  - SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7)

Overall it's minor and we can support this by defining a separate
struct sm5502_type for SM5504.

Hans de Goede a908a71669 ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c
The jack handling for arizona codecs is being refactored so that it is
done directly by the codec drivers, instead of having an extcon-driver
bind to a separate "arizona-extcon" child-device for this.

drivers/mfd/arizona-core.c has already been updated to no longer
instantiate an "arizona-extcon" child-device for the arizona codecs.

This means that the "arizona-extcon" driver is no longer useful
(there are no longer any devices for it to bind to).

This commit drops the extcon Kconfig / Makefile bits and moves
drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c .

This is a preparation patch for converting the arizona extcon-driver into
a helper library for letting the arizona codec-drivers directly report jack
state through the standard sound/soc/soc-jack.c functions.

Hans de Goede d54f063cdb extcon: axp288: Set USB role where necessary
The AXP288 BC1.2 charger detection / extcon code may seem like a strange
place to add code to control the USB role-switch on devices with an AXP288,
but there are 2 reasons to do this inside the axp288 extcon code:

1) On many devices the USB role is controlled by ACPI AML code, but the AML
   code only switches between the host and none roles, because of Windows
   not really using device mode. To make device mode work we need to toggle
   between the none/device roles based on Vbus presence, and the axp288
   extcon gets interrupts on Vbus insertion / removal.

2) In order for our BC1.2 charger detection to work properly the role
   mux must be properly set to device mode before we do the detection.

Also note the Kconfig help-text / obsolete depends on USB_PHY which are
remnants from older never upstreamed code also controlling the mux from
the axp288 extcon code.

This commit also adds code to get notifications from the INT3496 extcon
device, which is used on some devices to notify the kernel about id-pin
changes instead of them being handled through AML code.

This fixes:
-Device mode not working on most CHT devices with an AXP288
-Host mode not working on devices with an INT3496 ACPI device
-Charger-type misdetection (always SDP) on devices with an INT3496 when the
 USB role (always) gets initialized as host

Sergei Shtylyov 08a0a4f987 extcon: add Maxim MAX3355 driver
Maxim Integrated MAX3355E chip integrates a charge pump and comparators to
enable a system with an integrated USB OTG dual-role transceiver to
function as an USB OTG dual-role device. In addition to sensing/controlling
Vbus, the chip also passes thru the ID signal from the USB OTG connector.
On some Renesas boards, this signal is just fed into the SoC thru a GPIO
pin -- there's no real OTG controller, only host and gadget USB controllers
sharing the same USB bus; however, we'd like to allow host or gadget
drivers to be loaded depending on the cable type, hence the need for the
MAX3355 extcon driver. The Vbus status signals are also wired to GPIOs
(however, we aren't currently interested in them), the OFFVBUS# signal is
controlled by the host controllers, there's also the SHDN# signal wired to
a GPIO, it should be driven high for the normal operation.

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

Most Wolfson Arizona class audio hub CODECs include a flexible ultra low
power accessory detection subsystem. This driver exposes initial support
for this subsystem via the Extcon framework, implementing support for
ultra low power detection of headphone and headset with the ability to
detect the polarity of a headset.

The functionality of the devices is much richer and more flexible than
the current driver, future patches will extend the features of the
driver to more fully exploit this.

The extcon-max8997 driver is implemented based on 'drivers/misc/

function in struct max8997_muic_platform_data to notify cable state
of notifee which want to know always newly cable state when external
connector(e.g., USB, TA, JIG) is attached or detached.

v1
- Use Extcon interface to notify cable state of notifee instead of
 callback function when external connector is attached or detached.
- Bug fix of getting platform_data for irq_base value.
