extcon: add Maxim MAX3355 driver

2015-12-21T02:44:00Z

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

2015-12-15T01:02:34Z

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

2015-12-15T00:57:36Z

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

2015-11-20T01:14:23Z

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.

extcon: arizona: Add device binding for jack detect polarity inversion

2015-11-20T01:14:23Z

By default the driver expects the jackdet pin to be pulled low when a jack is inserted. This patch adds a device binding that allows the user to specify that the jackdet pin will be pulled high when a jack is inserted. Signed-off-by: Charles Keepax Acked-by: Chanwoo Choi Signed-off-by: Chanwoo Choi
