extcon: add Realtek DHC RTD SoC Type-C driver This patch adds the extcon driver for Realtek DHC (digital home center) RTD SoCs type-c module. This can be used to detect whether the port is configured as a downstream or upstream facing port. And notify the status of extcon to listeners.

extcon: sm5502: Add support for SM5703 SM5703 is another MFD from Silicon Mitus which has a very similar MUIC unit to the one in SM5502. The only difference I've noticed is slightly different configuration only enables the interrupts which are exactly the same as on SM5502. If we make use of different interrupts in the future, this can be improved by having a separate struct for SM5703, but the main functionality (detecting cable or OTG adapter) is working properly.

Some devices with the intel-cht-wc PMIC however come with an USB-micro-B connector, or an USB-2 only Type-C connector without USB-PD. Which device-model we are running on can be identified with the new cht_wc_model intel_soc_pmic field. On models without a Type-C controller the extcon code must control the Vbus 5V boost converter and the USB role switch depending on the detected cable-type.

extcon: extcon-axp288: Use P-Unit semaphore lock for register accesses use low level P-Unit semaphore lock for axp288 register accesses directly and for more than one access a time, to reduce the number of times this semaphore is locked and released which is an expensive operation. i2c-bus to the XPower is shared between the kernel and the SoCs P-Unit. The P-Unit has a semaphore wich the kernel must lock for axp288 register accesses. When the P-Unit semaphore is locked CPU and GPU power states cannot change or the system will freeze. The P-Unit semaphore lock is already managed inside the regmap access logic, but for each access the semaphore is locked and released. So use directly iosf_mbi_(un)block_punit_i2c_access(), we are safe in doing so because nested calls to the same semaphore are turned to nops.

ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.c The jack handling for arizona codecs is being refactored so that it is done directly by the codec drivers, instead of having an extcon-driver bind to a separate "arizona-extcon" child-device for this. drivers/mfd/arizona-core.c has already been updated to no longer instantiate an "arizona-extcon" child-device for the arizona codecs. This means that the "arizona-extcon" driver is no longer useful (there are no longer any devices for it to bind to). This commit drops the extcon Kconfig / Makefile bits and moves drivers/extcon/extcon-arizona.c to sound/soc/codecs/arizona-jack.c . This is a preparation patch for converting the arizona extcon-driver into a helper library for letting the arizona codec-drivers directly report jack state through the standard sound/soc/soc-jack.c functions.

extcon: axp288: Set USB role where necessary The AXP288 BC1.2 charger detection / extcon code may seem like a strange place to add code to control the USB role-switch on devices with an AXP288, but there are 2 reasons to do this inside the axp288 extcon code: 1) On many devices the USB role is controlled by ACPI AML code, but the AML code only switches between the host and none roles, because of Windows not really using device mode. To make device mode work we need to toggle between the none/device roles based on Vbus presence, and the axp288 extcon gets interrupts on Vbus insertion / removal. 2) In order for our BC1.2 charger detection to work properly the role mux must be properly set to device mode before we do the detection. Also note the Kconfig help-text / obsolete depends on USB_PHY which are remnants from older never upstreamed code also controlling the mux from the axp288 extcon code. This commit also adds code to get notifications from the INT3496 extcon device, which is used on some devices to notify the kernel about id-pin changes instead of them being handled through AML code. This fixes: -Device mode not working on most CHT devices with an AXP288 -Host mode not working on devices with an INT3496 ACPI device -Charger-type misdetection (always SDP) on devices with an INT3496 when the USB role (always) gets initialized as host Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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: rt8973a: Add Richtek RT8973A extcon driver 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.

This driver exposes initial support for this subsystem via the Extcon framework, implementing support for ultra low power detection of headphone and headset with the ability to detect the polarity of a headset.
