the hwspinlock and the IPC, which works for kicking interrupts between multiple cores in the SoC, are in one bus node but there is no overlapping register. hwspinlock: begin from 0x13240000 + 0x400 IPC: begin from 0x13240000, and end at begin from 0x13240000 + 0x400 - 0x4 ? so i guess we can refine the dts memory region to avoid MFD? > > Regards, > Bjorn -barry -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
