1*4882a593Smuzhiyun* Aspeed BT (Block Transfer) IPMI interface
2*4882a593Smuzhiyun
3*4882a593SmuzhiyunThe Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
4*4882a593Smuzhiyun(BaseBoard Management Controllers) and the BT interface can be used to
5*4882a593Smuzhiyunperform in-band IPMI communication with their host.

7*4882a593SmuzhiyunRequired properties:
8*4882a593Smuzhiyun
9*4882a593Smuzhiyun- compatible : should be one of
10*4882a593Smuzhiyun	"aspeed,ast2400-ibt-bmc"
11*4882a593Smuzhiyun	"aspeed,ast2500-ibt-bmc"
12*4882a593Smuzhiyun- reg: physical address and size of the registers
13*4882a593Smuzhiyun
14*4882a593SmuzhiyunOptional properties:
15*4882a593Smuzhiyun
16*4882a593Smuzhiyun- interrupts: interrupt generated by the BT interface. without an
17*4882a593Smuzhiyun  interrupt, the driver will operate in poll mode.
18*4882a593Smuzhiyun
19*4882a593SmuzhiyunExample:
20*4882a593Smuzhiyun
21*4882a593Smuzhiyun	ibt@1e789140 {
22*4882a593Smuzhiyun		compatible = "aspeed,ast2400-ibt-bmc";
23*4882a593Smuzhiyun		reg = <0x1e789140 0x18>;
24*4882a593Smuzhiyun		interrupts = <8>;
