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> |
