extcon: Add support for qcom SPMI PMIC USB id detection hardware

2016-09-13T02:26:26Z

Some Qualcomm PMICs have a misc device that performs USB id pin detection via an interrupt. When the interrupt triggers, we should read the interrupt line to see if it has gone high or low. If the interrupt is low then the ID pin is grounded, and if the interrupt is high then the ID pin is being held high.

extcon: link devres into core module

2016-06-30T13:18:40Z

Splitting the resource-managed functions into a separate module means that the extcon core now fails to build because the internal "extcon_dev_allocate" symbol is not exported: ERROR: extcon_dev_allocate [drivers/extcon/devres.ko] undefined! My guess is that the intention was not to have two separate modules (which could be fixed by adding an export, plus the normal MODULE_AUTHOR/MODULE_LICENSE/... fields), but have two source files in the same module. This fixes the Makefile accordingly, making the name of the module extcon_core.ko, which is created from building both extcon.c and devres.c.

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: axp288: Add axp288 extcon driver support

2015-05-19T07:39:04Z

This patch adds the extcon support for AXP288 PMIC which has the BC1.2 charger detection capability. Additionally it also adds the USB mux switching support b/w SOC and PMIC based on GPIO control.

extcon: Rename extcon core driver

2015-03-07T13:58:10Z

This patch renames the extcon core driver from extcon-class.c to extcon.c because '-class' postfix is not necessary. Signed-off-by: Chanwoo Choi

extcon: max77843: Add max77843 MUIC driver

extcon: usb-gpio: Introduce gpio usb extcon driver

2015-02-24T00:00:53Z

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.

extcon: rt8973a: Add Richtek RT8973A extcon driver

2014-09-22T02:43:08Z

This patch add support for Richtek RT8973A which is Micro USB Switch OVP and i2c interface. The RT8973A is a USB port accessory detector and switch that is optimized to protect low voltage system from abnormal high input voltage (up to 28V) and supports high speed USB operation. Also, RT8973A support 'auto-configuration' mode. If auto-configuration mode is enabled, RT8973A would control internal h/w patch for USB D-/D+ switching.

extcon: sm5502: Add support new SM5502 extcon device driver

2014-07-23T01:22:30Z

This patch add new SM5502 MUIC(Micro-USB Interface Controller) device by using EXTCON subsystem. The extcon-sm5502 driver is capable of identifying the type of the external power source and attached accessory. An external power sources, such as Deticated Charger or a standard USB port, are able to charge the battery in the smart phone via the connector. Signed-off-by: Chanwoo Choi
