The Aspeed BMC SoCs typically use the Keyboard-Controller-Style (KCS)
|
|
interfaces on the LPC bus for in-band IPMI communication with their host.

A 2-cell property expressing the LPC SerIRQ number and the interrupt
|
|
level/sense encoding (specified in the standard fashion).
|
|
|
|
Note that the generated interrupt is issued from the BMC to the host, and
|
|
thus the target interrupt controller is not captured by the BMC's
|
|
devicetree.
