[v1,0/4] Add EDAC driver for QCOM SoCs

Message

Venkata Narendra Kumar Gutta Aug. 1, 2018, 8:33 p.m. UTC

This series implements EDAC driver for QCOM SoCs. As of now, this driver
supports EDAC for Last Level Cache Controller (LLCC). LLCC EDAC driver is
to detect and report single and double bit errors on Last Level Cache
Controller (LLCC) cache. This driver also takes care of dumping registers
and also adding config options to enable and disable panic when these
errors happen in LLCC.

The driver functionality is implemented in:
qcom_edac.c : This platform driver registers to edac framework and
handles the single and double bit errors in cache by registering
interrupt handlers.

llcc-slice.c: It invokes the llcc edac driver and passes platform
data to it.

This patchset depends on the LLCC driver, which is yet to be merged.
