2016-06-30extcon: link devres into core moduleArnd Bergmann1-1/+2
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.

2016-06-10extcon: Remove the deprecated extcon functionsChanwoo Choi1-177/+24
This patch removes the deprecated extcon functions using string type to identify the type of external connector. The Commit 2a9de9c0f08d61 ("extcon: Use the unique id for external connector instead of string) uses the unique id to separate the type of external connector instead of string name. - extcon_register_interest() - extcon_unregister_interest() - extcon_set_cable_state() - extcon_get_cable_state() And, extcon_register_interest() finds the first extcon device to include the requested external connector from extcon client device and then register the notifier if extcon device argument is NULL. Instead, extcon_register_notifier() supports this feature. But, this patch remains the deprecatd function definition to prevent the build break. Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>

2015-12-21extcon: add Maxim MAX3355 driverSergei Shtylyov3-0/+156
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.

2015-09-29extcon: Export OF module alias information in missing driversJavier Martinez Canillas2-0/+2
The I2C core always reports the MODALIAS uevent as "i2c:<modalias>" regardless of the mechanism that was used to register the device (i.e: OF or board code) and the table that is used later to match the driver with the device (i.e: I2C id table or OF match table). So drivers needs to export the I2C id table and this be built into the module or udev won't have the necessary information to autoload the needed driver module when the device is added. But this means that OF-only drivers needs to have both OF and I2C id tables that have to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. Which can lead to issues if two vendors use the same I2C device name for example. To avoid the above, the I2C core behavior may be changed in the future to not require an SPI device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table even when is unused now to prevent breaking module loading when the core changes.

2015-09-22extcon: arizona: Don't disable debounce for inverted jacksCharles Keepax1-3/+5
Whilst the jack is connected we disable the jack detection debounce to ensure as quick as possible a detection of jack removal. However, it is only safe to disable the jack debounce whilst the jack is connected if using the micd clamp or the jack is not inverted. Otherwise spurious interrupts might be generated when we re-enable the debounce.

2015-09-22extcon: arizona: Use the micd_clamp for interrupts if it is availableCharles Keepax1-3/+3
Currently we only use the microphone clamp IRQ if GPIO5 is being used as a second jack detection pin. But we should be using it on any system where the clamp is available. This patch updates the driver to do so. Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
2015-09-22extcon: arizona: Ignore jd_invert for MICD_CLAMP_STSNariman Poushin1-4/+1
The polarity of MICD_CLAMP_STS does not change when different clamp modes are used, this patch corrects this issue.
