3  * In some cases UART attached devices which require an in kernel driver,
4  * e.g. UART attached Bluetooth HCIs are described in the ACPI tables
7  * This causes the kernel to create a /dev/ttyS# char-device for the UART
8  * instead of creating an in kernel serdev-controller + serdev-device pair
12  * create a serdev-controller device for these UARTs instead of a /dev/ttyS#.
14  * Instantiating the actual serdev-device to bind to is up to pdx86 code,
15  * this header provides a helper for getting the serdev-controller device.
