* edac, highbank: Moving error injection to sysfs for edacRobert Richter2013-11-041-35/+20
| | | | | | | | | | | | | | | | | | | Always have the error injection i/f available, even if there is no debugfs or EDAC_DEBUG enabled. We need this for testing production kernels and environments. Thus, the entry moves from: /sys/kernel/debug/edac/mc0/inject_ctrl to: /sys/devices/system/edac/mc/mc0/inject_ctrl No other changes of the interface.

* edac, highbank: Improve and unify namingRobert Richter2013-11-041-2/+3
| | | | | | | | | | | | | | | | Assinging correct names of the 'hb_mc_edac' and 'hb_l2_edac' edac modules for module, controller and device. Reported values for Highbank in dmesg are now: EDAC MC0: Giving out device to module hb_mc_edac controller calxeda,hb-ddr-ctrl: DEV fff00000.memory-controller (INTERRUPT) EDAC DEVICE0: Giving out device to module hb_l2_edac controller calxeda,hb-sregs-l2-ecc: DEV fff3c200.sregs (INTERRUPT) Signed-off-by: Robert Richter <robert.richter@linaro.org> Acked-by: Rob Herring <rob.herring@calxeda.com> Signed-off-by: Robert Richter <rric@kernel.org>
* edac, highbank: Add Calxeda ECX-2000 supportRobert Richter2013-11-041-35/+70
| | | | | | | | | | | | | Implement edac support for Calxeda ECX-2000. The ECX-2000 memory controller is similar to Highbank but has different register bases for error and interrupt registers. There is an own device tree name "calxeda,ecx-2000-ddr-ctrl" for identification and initialization of the ECX-2000 and its base addresses.

* Drivers: edac: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

| | | | | | | | | | | | This removes an open coded simple_open() function and replaces file operations references to the function with simple_open() instead. dpatch engine is used to auto generate this patch.
