Subject: [PATCH 0/8] GPIO extcon modernization

Like with the GPIO mouse input, I found that this driver has no in-tree
users at all.

I *could* just propose to delete it. But the driver seems generally useful,
so I made a patch series shaping it up to get configuration from device
tree or ACPI DSDT using device properties instead.

We start off the series by defining a set of device tree bindings for it.

It would be great to have some input from the initial authors on this
rewrite. I think we would not merge any board file using the platform
data anymore, so making it an all-in device property (device tree || ACPI)
driver seems reasonable.

Linus Walleij (8):
  extcon: gpio: Add DT bindings
  extcon: gpio: Localize platform data
  extcon: gpio: Move platform data into state container
  extcon: gpio: Convert to fully use GPIO descriptor
  extcon: gpio: Request reasonable interrupts
  extcon: gpio: Get debounce setting from device property
  extcon: gpio: Get connector type from device property
  extcon: gpio: Always check state on resume
