extcon: add Maxim MAX3355 driver

2015-12-21T02:44:00+00:00

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.

extcon: arizona: Update device tree binding for mic detect configurations

2015-12-15T00:57:37+00:00

Update the device tree binding documentation to include documentation for
the wlf,micd-configs property that is used to specify the configurations
for headset polarity detection (CTIA / OTMP).

extcon: arizona: Update naming for second jack detection DT binding

2015-11-23T23:59:11+00:00

extcon: arizona: Update DT binding documentation for jack detection

2015-11-20T01:14:24+00:00

Add additional bindings for both inverting the polarity of the jack
detection pins and allowing the use of a second jack detection pin. Note
that the second jack detection pin is hard wired in the chip so can only
be enabled through the binding, rather than a pin being specified.

extcon: arizona: Add extcon specific device tree binding document

2015-10-30T18:57:37+00:00

Subsystem specific bindings for the Arizona devices are being factored
out of the MFD binding document into separate documents for each
subsystem. This patch adds a binding document that covers the existing
extcon specific bindings.

extcon: palmas: Support GPIO based USB ID detection

2015-08-10T12:26:25+00:00

Some palmas based chip variants do not have OTG based ID logic.
For these variants we rely on GPIO based USB ID detection.

These chips do have VBUS comparator for VBUS detection so we
continue to use the old way of detecting VBUS.

extcon: usb-gpio: Introduce gpio usb extcon driver

2015-02-24T00:00:53+00:00

This driver observes the USB ID pin connected over a GPIO and
updates the USB cable extcon states accordingly.

The existing GPIO extcon driver is not suitable for this purpose
as it needs to be taught to understand USB cable states and it
can't handle more than one cable per instance.

For the USB case we need to handle 2 cable states.
1) USB (attach/detach)
2) USB-HOST (attach/detach)

This driver can be easily updated in the future to handle VBUS
events in case it happens to be available on GPIO for any platform.
