Merge tag 'extcon-next-for-7.1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon into char-misc-next
Chanwoo writes: Update extcon next for v7.1 Detailed description for this pull request: - Fix sysfs duplicate filename issue on extcon core : Adjust ida_free timing after device_unregister to prevent duplicate filename error when re-allocating id - Update NXP PTN5150 extcon driver and dt-binding document : Handle pending IRQ events during system resume : Allow "connector" node to present in devicetree : Add Type-C orientation switch support to correctly set orientation of multiplexer according to CC status : Support USB role switch via connector fwnode - Replace use of system_wq with system_percpu_wq on int3496 driver - Make typec-power-opmode optional on usbc-tusb320 driver : Prevent probe error when usb-c connector is configured in the DT without "typec-power-opmode" property * tag 'extcon-next-for-7.1' of ssh://gitolite.kernel.org/pub/scm/linux/kernel/git/chanwoo/extcon: extcon: usbc-tusb320: Make typec-power-opmode optional extcon: ptn5150: Support USB role switch via connector fwnode extcon: ptn5150: Add Type-C orientation switch support dt-bindings: extcon: ptn5150: Allow "connector" node to present extcon: Fixed sysfs duplicate filename issue extcon: int3496: replace use of system_wq with system_percpu_wq extcon: ptn5150: handle pending IRQ events during system resume
