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.
