I will delete node for this clock from DT and send v1 > Sorry for the html reply first of all. That node should never have been actually added since the clock is not suppose to be touched even in low power states. Change log should say something like this ... "MSMC is the coherency interconnect and all the coherent masters are connected to it including devices which are not under Linux OS control. MSMC clock should not be toched even in low power states." So drop the clock node o.w without 'clk_ignore_unused' will disable the clock leading to system stall. I wil try get these in rc's since its a bug fix Regards, Santosh -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
