| * EDAC, pci_sysfs: remove unneccessary ifdef around entire fileAndreas Ruprecht2014-11-112-6/+1Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The file edac_pci_sysfs.c is dependent on CONFIG_PCI. This is already modelled in the Makefile, but edac_pci_sysfs.o is still contained in the list of files compiled even without CONFIG_PCI. This change removes edac_pci_sysfs.o from the list of built objects when not having CONFIG_PCI enabled and removes the then-unnecessary ifdef from the source file.

| * ghes_edac: Use snprintf() to silence a static checker warningDan Carpenter2014-11-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My static checker complains because the "e->location" has up to 256 characters but we are copying it into the "pvt->detail_location" which only has space for 240 characters. That's not counting the surrounding text and the "e->other_detail" string which can be over 80 characters long. I am not familiar with this code but presumably it normally works. Let's add a limit though for safety.

| * amd64_edac: Add F15h M60h supportAravind Gopalakrishnan2014-10-302-82/+188
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds support for ECC error decoding for F15h M60h processor. Aside from the usual changes, the patch adds support for some new features in the processor: - DDR4(unbuffered, registered); LRDIMM DDR3 support - relevant debug messages have been modified/added to report these memory types - new dbam_to_cs mappers - if (F15h M60h && LRDIMM); we need a 'multiplier' value to find cs_size. This multiplier value is obtained from the per-dimm DCSM register. So, change the interface to accept a 'cs_mask_nr' value to facilitate this calculation - switch-casing determine_memory_type() - done to cleanse the function of too many if-else statements and improve readability - This is now called early in read_mc_regs() to cache dram_type Misc cleanup: - amd64_pci_table[] is condensed by using PCI_VDEVICE macro. Testing details: Tested the patch by injecting 'ECC' type errors using mce_amd_inj and error decoding works fine.

But it did from the device pm suspend handler while the regulator suspend prepare function iterates over all regulators and not only the one managed by this device so it doesn't seems to be correct to call it from within a device driver. It is better to call the regulator suspend prepare/finish functions from platform code instead so this patch reverts the mentioned commit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a "maxim,max77693-charger" of_compatible to the mfd_cell so the MFD child device (the charger) will have its own of_node set. This will be used by the max77693 charger driver in next patches to obtain battery configuration from DTS.

This way concurrent accesses to the iomem range are handled by the regmap framework, and each subdevice can safely access HLCDC registers.

| * | mfd: core: Fix platform-device id generationJohan Hovold2014-11-251-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make sure to always honour multi-function devices registered with PLATFORM_DEVID_NONE (-1) or PLATFORM_DEVID_AUTO (-2) as id base. In this case it does not make sense to append the cell id to the mfd-id base and potentially change the requested behaviour. Specifically this will allow multi-function devices to be registered with PLATFORM_DEVID_AUTO while still having non-zero cell ids.
