From 1ee695fab32e25ff188c98a145cc93674f594923 Mon Sep 17 00:00:00 2001 From: "J. German Rivera" Date: Wed, 23 Sep 2015 16:11:03 -0500 Subject: [PATCH] staging: fsl-mc: up-rev dprc binary interface to v4.0 Add cmd_flags parameter to all dprc APIs to comply with the dprc 4.0 MC interface. Updated MC version major number. Pass irq args in struct instead of separate args. dprc 4.0 uses MC-relative offsets to specify object regions, instead of physical addresses. So, translate_mc_addr() and struct fsl_mc_addr_translation_range need to be updated accordingly. Update commands for 4.0: add new commands 'set/get obj irq', 'set obj label', 'get obj descriptor'. Remove 'get portal paddr'. Signed-off-by: J.
