Adds support for the error notification. Currently 20 errors has been tested. This driver is receiving events over rpmsg. It does not access the registers by itself instead the NMC reads and sends the info by rpmsg Also we register the edac once and it reports the errors for all the events including the 8 DDRMC controllers. So while registering we give the particulars of the 1st controller. Changes in v3: make remove void Changes in v2: - Remove the dwidth, rank and channel number the same is read from the RpMsg. - rename EDAC to memory controller - update the compatible name - Add remote proc handle - remove reset - Add the remote proc requests - remove probe_once - reorder the rpmsg registration - Export the symbols for module compilation Shubhrajyoti Datta (5): cdx: export the symbols ras: export the log_non_standard_event cdx: add DDRMC commands dt-bindings: memory-controllers: Add support for Versal NET EDAC EDAC: Versal NET: Add support for error notification .../amd,versalnet-ddrmc.yaml | 40 + drivers/cdx/controller/mc_cdx_pcol.h | 16 + drivers/cdx/controller/mcdi.c | 3 + drivers/edac/Kconfig | 9 + drivers/edac/Makefile | 1 + drivers/edac/versalnet_rpmsg_edac.c | 1326 +++++++++++++++++ drivers/ras/ras.c | 1 + 7 files changed, 1396 insertions(+) create mode 100644 Documentation/devicetree/bindings/memory-controllers/amd,versalnet-ddrmc.yaml create mode 100644 drivers/edac/versalnet_rpmsg_edac.c -- 2.17.1
