^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) The Intel INT3496 ACPI device extcon driver is a driver for ACPI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) devices with an acpi-id of INT3496, such as found for example on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) Intel Baytrail and Cherrytrail tablets.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) This ACPI device describes how the OS can read the id-pin of the devices'
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) USB-otg port, as well as how it optionally can enable Vbus output on the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) otg port and how it can optionally control the muxing of the data pins
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) between an USB host and an USB peripheral controller.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) The ACPI devices exposes this functionality by returning an array with up
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) to 3 gpio descriptors from its ACPI _CRS (Current Resource Settings) call:

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) =======  =====================================================================
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) Index 0  The input gpio for the id-pin, this is always present and valid
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) Index 1  The output gpio for enabling Vbus output from the device to the otg
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20)          port, write 1 to enable the Vbus output (this gpio descriptor may
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21)          be absent or invalid)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) Index 2  The output gpio for muxing of the data pins between the USB host and
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23)          the USB peripheral controller, write 1 to mux to the peripheral

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) There is a mapping between indices and GPIO connection IDs as follows
