extcon: max77843: Use correct size for reading the interrupt register

2016-05-04T21:49:16+00:00

commit c4924e92442d7218bd725e47fa3988c73aae84c9 upstream.

The info->status[] array has 3 elements.  We are using size
MAX77843_MUIC_IRQ_NUM (16) instead of MAX77843_MUIC_STATUS_NUM (3) as
intended.

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: max77843: fix handling return value of regmap_irq_get_virq

2015-12-15T01:02:34+00:00

The function can return negative values, so its result should
be assigned to signed variable.

The problem has been detected using proposed semantic patch
scripts/coccinelle/tests/assign_signed_to_unsigned.cocci [1].

extcon: arizona: Add device bindings for the micd configurations

2015-12-15T00:57:36+00:00

Add device bindings to support configuring the jack detection
configurations. Each configuration needs to specify the connection of
the mic det pins, which micbias should be used and the value of the
micd polarity GPIO required to activate that configuration.

extcon: arizona: Add device binding for second jack detect pin on GPIO5

2015-11-20T01:14:23+00:00

Some Arizona devices have the option to use the GPIO5 pin as a second
jack detection pin. This patch adds device bindings to specify to the
driver that it should use this 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.
