Hello to all, The goal of this WIP set is to provide support for sub-functional hw blocks inside Qualcomm QPNP PMIC chips by creating a new qpnp bus (device-driver modeled). On SPMI interface we attach a so called Slaves. For example one PMIC chip like pm8941 has two slave id's. On every slaveid the PMIC chip has various peripherials. Every peripheral driver should expose qpnp_driver structure and implement the .probe and .remove callbacks. Every peripheral driver will reside on the proper place in /drivers directory. The fisrt patch describes the devicetree binding of the slave devices attached to the SPMI interface. The second patch adds implemetation of the qpnp-bus and a layer connection with the SPMI interface. The third patch adds spmi arbiter and underlying slaveid devicetree nodes for msm8974 SoC. The other patches are example of rtc-qpnp driver and binding documentation. Since this set is a WIP, it will be used as a starting point for future duscussions about implementing QPNP PMIC sub-function hw blocks. Regards, Stan Ivan T.
