Thunderbolt hotplug is supposed to be handled by the firmware. But Apple decided to implement thunderbolt at the operating system level. The firmare only initializes thunderbolt devices that are present at boot time. This driver enables hotplug of thunderbolt of non-chained thunderbolt devices on Apple systems with a cactus ridge controller. This first patch adds the Kconfig file as well the parts of the driver which talk directly to the hardware (that is pci device setup, interrupt handling and RX/TX ring management).

Cactus Ridge Thunderbolt Controller driver
|
|
This driver is required if you want to hotplug Thunderbolt devices on
|
|
Apple hardware.
|
|
|
|
Device chaining is currently not supported.
|
|
|
|
To compile this driver a module, choose M here. The module will be
|
|
called thunderbolt.
