2018-03-22extcon: axp288: Set USB role where necessaryHans de Goede
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>

2018-01-03extcon: axp288: Redo charger type detection a couple of seconds after probe()Hans de Goede

This commit starts a second charger-detection cycle a couple of seconds after the first one finishes, giving the other drivers time to load and do their thing.

2017-10-23extcon: Split out extcon header file for consumer and provider deviceChanwoo Choi
The extcon has two type of extcon devices as following. - 'extcon provider deivce' adds new extcon device and detect the state/properties of external connector. Also, it notifies the state/properties to the extcon consumer device. - 'extcon consumer device' gets the change state/properties from extcon provider device. Prior to that, include/linux/extcon.h contains all exported API for both provider and consumer device driver. To clarify the meaning of header file and to remove the wrong use-case on consumer device, this patch separates into extcon.h and extcon-provider.h. [Description for include/linux/{extcon.h|extcon-provider.h}] - extcon.h includes the extcon API and data structure for extcon consumer device driver. This header file contains the following APIs: : Register/unregister the notifier to catch the change of extcon device : Get the extcon device instance : Get the extcon device name : Get the state of each external connector : Get the property value of each external connector : Get the property capability of each external connector - extcon-provider.h includes the extcon API and data structure for extcon provider device driver.

2017-01-09extcon: axp288: Use vbus-valid instead of -present to determine cable presenceHans de Goede
The vbus-present bit in the power status register also gets set to 1 when a usb-host cable (id-pin shorted to ground) is plugged in and a 5v boost converter is supplying 5v to the otg usb bus. This causes a "disconnect or unknown or ID event" warning in dmesg as well as the extcon device to report the last detected charger cable type as being connected even though none is connected. This commit switches to checking the vbus-valid bit instead, which is only 1 when both vbus is present and the vbus-path is enabled in the vbus-path control register (the vbus-path gets disabled when a usb-host cable is detected, to avoid the pmic drawing power from the 5v boost converter).

So we can simply always do both on each interrupt removing a bunch of somewhat magic looking code from axp288_handle_chrg_det_event.

2017-01-09extcon: axp288: Remove usb_phy notification codeHans de Goede
The usb_phy based intel-usb-phy code never got merged into the mainline kernel, so the devm_usb_get_phy() call will always fail, blocking the driver from loading. Since new drivers should use the generic-phy framework, not the old-style usb_phy stuff, keeping this around is not useful. Therefor this patch removes the usb_phy notification bits, which together with the patch to remove the platform_data dependency, makes this driver actually successfully probe on systems with an axp288 pmic.

2017-01-09extcon: axp288: Remove dependency on non-existing platform_dataHans de Goede
When the extcon_axp288 driver was originally merged, it was merged with a dependency on some other driver providing platform data for it. However such another driver was never merged, so the extcon_axp288 as merged upstream has never worked, its probe method simply always returns -ENODEV. This commit drops the dependency on the pdata always being there, instead it treats not having pdata as the pdata having a NULL gpio_mux_control, something which the code was already prepared to handle. Note that the code for controlling the mux_control gpio is left in place, as this may be necessary to allow the axp288 pmic to properly detect the charger type (instead of assuming 500mA max charge current) on some tablets. This will make it easier for future patches to add support for this gpio by getting the gpio info from somewhere.

2015-05-22extcon: Use the unique id for external connector instead of stringChanwoo Choi
This patch uses the unique id to identify the type of external connector instead of string name. The string name have the many potential issues. So, this patch defines the 'extcon' enumeration which includes all supported external connector on EXTCON subsystem. If new external connector is necessary, the unique id of new connector have to be added in 'extcon' enumeration. There are current supported external connector in 'enum extcon' as following: enum extcon { EXTCON_NONE = 0x0, /* USB external connector */ EXTCON_USB = 0x1, EXTCON_USB_HOST = 0x2, /* Charger external connector */ EXTCON_TA = 0x10, EXTCON_FAST_CHARGER = 0x11, EXTCON_SLOW_CHARGER = 0x12, EXTCON_CHARGE_DOWNSTREAM = 0x13, /* Audio and video external connector */ EXTCON_LINE_IN = 0x20, EXTCON_LINE_OUT = 0x21, EXTCON_MICROPHONE = 0x22, EXTCON_HEADPHONE = 0x23, EXTCON_HDMI = 0x30, EXTCON_MHL = 0x31, EXTCON_DVI = 0x32, EXTCON_VGA = 0x33, EXTCON_SPDIF_IN = 0x34, EXTCON_SPDIF_OUT = 0x35, EXTCON_VIDEO_IN = 0x36, EXTCON_VIDEO_OUT = 0x37, /* Miscellaneous external connector */ EXTCON_DOCK = 0x50, EXTCON_JIG = 0x51, EXTCON_MECHANICAL = 0x52, EXTCON_END, }; For example in extcon-arizona.c: To use unique id removes the potential issue about handling the inconsistent name of external connector with string. - Previously, use the string to register the type of arizona jack connector static const char *arizona_cable[] = { "Mechanical", "Microphone", "Headphone", "Line-out", }; - Newly, use the unique id to register the type of arizona jack connector static const enum extcon arizona_cable[] = { EXTCON_MECHANICAL, EXTCON_MICROPHONE, EXTCON_HEADPHONE, EXTCON_LINE_OUT, EXTCON_NONE, }; And this patch modify the prototype of extcon_{get|set}_cable_state_() which uses the 'enum extcon id' instead of 'cable_index'. Because although one more extcon drivers support USB cable, each extcon driver might has the differnt 'cable_index' for USB cable. All extcon drivers can use the unique id number for same external connector with modified extcon_{get|set}_cable_state_(). - Previously, use 'cable_index' on these functions: extcon_get_cable_state_(struct extcon_dev*, int cable_index) extcon_set_cable_state_(struct extcon_dev*, int cable_index, bool state) -Newly, use 'enum extcon id' on these functions: extcon_get_cable_state_(struct extcon_dev*, enum extcon id) extcon_set_cable_state_(struct extcon_dev*, enum extcon id, bool state) Cc: Arnd Bergmann <arnd@arndb.de> Cc: Felipe Balbi <balbi@ti.com> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com> Acked-by: Roger Quadros <rogerq@ti.com> Acked-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Acked-by: Ramakrishna Pallala <ramakrishna.pallala@intel.com> Reviewed-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> [arnd: Report the build break about drivers/usb/phy/phy-tahvo.c after using the unique id for external connector insteadf of string] Reported-by: Arnd Bergmann <arnd@arndb.de> [dan.carpenter: Report the build warning of extcon_{set|get}_cable_state_()] Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
