Hi, Changes since v1: - Fixed issue introduced by the bitops patch: wrong error check, also switch to use find_first_zero_bit() instead of find_next_zero_bit() Cover letter: This series depends on the eDMA work I have done, which has been now applied: https://lkml.org/lkml/2015/10/16/64 DRA7 family of chips have both sDMA and eDMA. Currently only sDMA can be used becasue the old driver stack for eDMA did not allowed integration w/o hacks. Due to the nature of eDMA the crossbar needs to know which eDMA events it can use to map incoming events towards the eDMA. In eDMA a channel is wired to be used with one specific event. For example eDMA event 14 can only be handled by eDMA channel 14. The eDMA itself can be shared by different processors in the system (ARM, DSP, etc) and since ARM/Linux is the master we need to know which channels are used by other cores. Also we need to mask out channels used for memcpy from the events we use for HW triggers.
