SPMI obsoletes a number of legacy, custom point-to-point interfaces and provides a low pin count, high-speed control bus for up to 4 Master and 16 Slave devices. SPMI is specified by the MIPI (Mobile Industry Process Interface) Alliance [1]. Introduced in this patchset are the core SPMI bus components, as well an implementation of an SPMI controller, the "PMIC arbiter", which is used on several Qualcomm SoCs to communicate with off-chip Power Management ICs (PMICs). Notably missing from this patchset is an implementation of a spmi device/slave driver, which is still forthcoming. With this patchset in it's current state, it is possible to perform register accesses to a slave via debugfs.
