This patchset adds support for the Krait L1/L2 cache error detection
hardware. The second patch adds the Krait L2 indirection
register code. This patch is in need of an ACK from ARM folks.
The next two patches add the driver and the binding and
the final patch fixes up the DT nodes to match the binding (this last
one should go through the arm-soc tree).
NOTE: the DT binding patches rely on Lorenzo's cache DT binding document[1]
Changes since v5:
* Don't rely on platform device being created from cpus node
* Get interrupts from L1 cache node
* Rework binding to be in cache document
Changes since v4:
* Prefixed l2 accessors functions with krait_
* Dropped first two patches as Boris says he picked them up
Changes since v3:
* Fixed l1_irq handler to properly dereference dev_id
Changes since v2:
* Picked up acks
* s/an/a/ in DT binding
Stephen Boyd (5):
genirq: export percpu irq functions for module usage
ARM: Add Krait L2 register accessor functions
devicetree: bindings: Document Krait cache error interrupts
edac: Add support for Krait CPU cache error detection
ARM: dts: msm: Fix Krait CPU/L2 nodes
