1*c66ec88fSEmmanuel Vadot* Qualcomm SSBI 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotSome Qualcomm MSM devices contain a point-to-point serial bus used to 4*c66ec88fSEmmanuel Vadotcommunicate with a limited range of devices (mostly power management 5*c66ec88fSEmmanuel Vadotchips). 6*c66ec88fSEmmanuel Vadot 7*c66ec88fSEmmanuel VadotThese require the following properties: 8*c66ec88fSEmmanuel Vadot 9*c66ec88fSEmmanuel Vadot- compatible: "qcom,ssbi" 10*c66ec88fSEmmanuel Vadot 11*c66ec88fSEmmanuel Vadot- qcom,controller-type 12*c66ec88fSEmmanuel Vadot indicates the SSBI bus variant the controller should use to talk 13*c66ec88fSEmmanuel Vadot with the slave device. This should be one of "ssbi", "ssbi2", or 14*c66ec88fSEmmanuel Vadot "pmic-arbiter". The type chosen is determined by the attached 15*c66ec88fSEmmanuel Vadot slave. 16*c66ec88fSEmmanuel Vadot 17*c66ec88fSEmmanuel VadotThe slave device should be the single child node of the ssbi device 18*c66ec88fSEmmanuel Vadotwith a compatible field. 19
