1*4882a593Smuzhiyun* Qualcomm SSBI 2*4882a593Smuzhiyun 3*4882a593SmuzhiyunSome Qualcomm MSM devices contain a point-to-point serial bus used to 4*4882a593Smuzhiyuncommunicate with a limited range of devices (mostly power management 5*4882a593Smuzhiyunchips). 6*4882a593Smuzhiyun 7*4882a593SmuzhiyunThese require the following properties: 8*4882a593Smuzhiyun 9*4882a593Smuzhiyun- compatible: "qcom,ssbi" 10*4882a593Smuzhiyun 11*4882a593Smuzhiyun- qcom,controller-type 12*4882a593Smuzhiyun indicates the SSBI bus variant the controller should use to talk 13*4882a593Smuzhiyun with the slave device. This should be one of "ssbi", "ssbi2", or 14*4882a593Smuzhiyun "pmic-arbiter". The type chosen is determined by the attached 15*4882a593Smuzhiyun slave. 16*4882a593Smuzhiyun 17*4882a593SmuzhiyunThe slave device should be the single child node of the ssbi device 18*4882a593Smuzhiyunwith a compatible field. 19
