2022-02-01extcon: intel-cht-wc: Support devs with Micro-B / USB-2 only Type-C connectorsHans de Goede1-0/+2
So far the extcon-intel-cht-wc code has only been tested on devices with a Type-C connector with USB-PD, USB3 (superspeed) and DP-altmode support through a FUSB302 Type-C controller. 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.

2021-10-27extcon: extcon-axp288: Use P-Unit semaphore lock for register accessesFabio Aiuto1-1/+1
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.

2021-06-21extcon: sm5502: Add support for SM5504Stephan Gerhold1-1/+1
SM5504 is another MUIC from Silicon Mitus that is fairly similar to SM5502. They seem to use the same register set, but: - SM5504 has some additional bits in SM5502_REG_CONTROL - SM5504 has a quite different set of interrupts - SM5504 reports USB OTG as dev_type1 = BIT(0) instead of BIT(7) Overall it's minor and we can support this by defining a separate struct sm5502_type for SM5504.

2021-03-18ASoC/extcon: arizona: Move arizona jack code to sound/soc/codecs/arizona-jack.cHans de Goede1-8/+0
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.

2018-03-22extcon: axp288: Set USB role where necessaryHans de Goede1-1/+2
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>

2015-12-21extcon: add Maxim MAX3355 driverSergei Shtylyov1-0/+9
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.

Fix up mostly trivial conflicts, with the exception of drivers/usb/host/ehci-omap.c in particular, which had some re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI: centralize controller initialization") that clashed with commit 2761a6394516 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix issues"). In particular, commit 2761a6394516 moved the usb_add_hcd() to the *middle* of the reset sequence, which clashes fairly badly with the reset sequence re-organization (although it could have been done inside the new omap_ehci_init() function).

2012-06-27Extcon: Arizona: Add driver for Wolfson Arizona class devicesMark Brown1-0/+8
Most Wolfson Arizona class audio hub CODECs include a flexible ultra low power accessory detection subsystem. 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. The functionality of the devices is much richer and more flexible than the current driver, future patches will extend the features of the driver to more fully exploit this.

The extcon-max8997 driver is implemented based on 'drivers/misc/ max8997-muic.c' and then use Extcon interface instead of callback function in struct max8997_muic_platform_data to notify cable state of notifee which want to know always newly cable state when external connector(e.g., USB, TA, JIG) is attached or detached. v1 - Use Extcon interface to notify cable state of notifee instead of callback function when external connector is attached or detached. - Bug fix of getting platform_data for irq_base value.
