extcon: adc-jack: Cleanup wakeup source only if it was enabled

2025-11-13T20:34:41+00:00

commit 92bac7d4de9c07933f6b76d8f1c7f8240f911f4f upstream. Driver in the probe enables wakeup source conditionally, so the cleanup path should do the same - do not release the wakeup source memory if it was not allocated.

extcon: adc-jack: Fix wakeup source leaks on device unbind

2025-11-13T20:34:15+00:00

[ Upstream commit 78b6a991eb6c6f19ed7d0ac91cda3b3b117fda8f ] Device can be unbound, so driver must also release memory for the wakeup source. Do not use devm interface, because it would change the order of cleanup.

Immutable branch for usb_types change for v6.12 Changing usb_types type from array to bitmap in the power_supply_desc struct requires updating power-supply drivers living in different subsystem, so it is handled via an immutable branch.

extcon: Add LC824206XA microUSB switch driver

2024-09-04T15:43:08+00:00

Add a new driver for the ON Semiconductor LC824206XA microUSB switch and accessory detector chip. ON Semiconductor has an "Advance Information" datasheet available (ENA2222-D.PDF), but no full datasheet. So there is no documentation available for the registers. This driver is based on the register info from the extcon-fsa9285.c driver, from the Lollipop Android sources for the Lenovo Yoga Tablet 2 (Pro) 830 / 1050 / 1380 models. Note despite the name this is actually a driver for the LC824206XA not the FSA9285. This has only been tested on a Lenovo Yoga Tablet 2 Pro 1380 and using the driver on other setups may require additional work. So far this driver is only used on x86/ACPI (non devicetree) devs. Therefor there is no devicetree bindings documentation for this driver's "onnn,enable-miclr-for-dcp" property since this is not used in actual devicetree files and the dt bindings maintainers have requested properties with no actual dt users to _not_ be added to the dt bindings.

power: supply: Change usb_types from an array into a bitmask

2024-09-03T21:20:28+00:00

The bit_types array just hold a list of valid enum power_supply_usb_type values which map to 0 - 9. This can easily be represented as a bitmap. This reduces the size of struct power_supply_desc and further reduces the data section size by drivers no longer needing to store the array. This also unifies how usb_types are handled with charge_behaviours, which allows power_supply_show_usb_type() to be removed.
