EDAC: Drop per-memory controller buses

2018-11-13T20:55:24+00:00

... and use the single edac_subsys object returned from
subsys_system_register(). The idea is to have a single bus
and multiple devices on it.

EDAC: Add missing MEM_LRDDR4 entry in edac_mem_types[]

2018-08-17T13:13:34+00:00

The edac_mem_types[] array misses a MEM_LRDDR4 entry, which leads to
NULL pointer dereference when accessed via sysfs or such.

EDAC: Add new memory type for non-volatile DIMMs

2018-03-14T11:32:06+00:00

There are now non-volatile versions of DIMMs. Add a new entry to "enum
mem_type" and a new string in edac_mem_types[].

EDAC: Drop duplicated array of strings for memory type names

2018-03-14T11:20:16+00:00

Somehow we ended up with two separate arrays of strings to describe the
"enum mem_type" values.

In edac_mc.c we have an exported list edac_mem_types[] that is used
by a couple of drivers in debug messaged.

In edac_mc_sysfs.c we have a private list that is used to display
values in:
  /sys/devices/system/edac/mc/mc*/dimm*/dimm_mem_type
  /sys/devices/system/edac/mc/mc*/csrow*/mem_type

This list was missing a value for MEM_LRDDR3.

The string values in the two lists were different :-(

Combining the lists, I kept the values so that the sysfs output
will be unchanged as some scripts may depend on that.

EDAC: Add helper which returns the loaded platform driver

2017-09-25T10:55:59+00:00

Only a single EDAC platform driver can be loaded. When ghes_edac is
enabled, an EDAC platform driver still attempts to register itself and
fails in edac_mc_add_mc().

Add edac_get_owner() so that EDAC platform drivers can check the owner
first.
