ARM: dts: Add Altera L2 Cache and OCRAM EDAC entries
Add the device tree entries and bindings needed to support the Altera L2 cache and On-Chip RAM EDAC. This patch relies upon an earlier patch to declare and setup On-chip RAM properly: 8b907c8b62ac ("arm: dts: socfpga: Add OCRAM node") Signed-off-by: Thor Thayer <tthayer@opensource.altera.com> Acked-by: Rob Herring <robh@kernel.org> Cc: devicetree@vger.kernel.org Cc: Dinh Nguyen <dinguyen@opensource.altera.com> Cc: galak@codeaurora.org Cc: grant.likely@linaro.org Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: ijc+devicetree@hellion.org.uk Cc: Kumar Gala <galak@codeaurora.org> Cc: linux-arm-kernel@lists.infradead.org Cc: linux@arm.linux.org.uk Cc: linux-doc@vger.kernel.org Cc: linux-edac <linux-edac@vger.kernel.org> Cc: Mark Rutland <mark.rutland@arm.com> Cc: m.chehab@samsung.com Cc: Pawel Moll <pawel.moll@arm.com> Cc: Rob Herring <robh+dt@kernel.org> Cc: Russell King <linux@arm.linux.org.uk> Link: http://lkml.kernel.org/r/1455132384-17108-2-git-send-email-tthayer@opensource.altera.com Signed-off-by: Borislav Petkov <bp@suse.de>

+Altera SoCFPGA ECC Manager
+This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
+The ECC Manager counts and corrects single bit errors and counts/handles
+double bit errors which are uncorrectable.
+
+Required Properties:
+- compatible : Should be "altr,socfpga-ecc-manager"
+- #address-cells: must be 1
+- #size-cells: must be 1
+- ranges : standard definition, should translate from local addresses
+
+Subcomponents:
+
+L2 Cache ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-l2-ecc"
+- reg : Address and size for ECC error interrupt clear registers.
+- interrupts : Should be single bit error interrupt, then double bit error
+ interrupt. Note the rising edge type.
+
+On Chip RAM ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-ocram-ecc"
+- reg : Address and size for ECC error interrupt clear registers.
+- iram : phandle to On-Chip RAM definition.
+- interrupts : Should be single bit error interrupt, then double bit error
+ interrupt. Note the rising edge type.
+
+Example:
+
+ eccmgr: eccmgr@ffd08140 {
+ compatible = "altr,socfpga-ecc-manager";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ l2-ecc@ffd08140 {
+ compatible = "altr,socfpga-l2-ecc";
+ reg = <0xffd08140 0x4>;
+ interrupts = <0 36 1>, <0 37 1>;
+ };
+
+ ocram-ecc@ffd08144 {
+ compatible = "altr,socfpga-ocram-ecc";
+ reg = <0xffd08144 0x4>;
+ iram = <&ocram>;
+ interrupts = <0 178 1>, <0 179 1>;
+ };
+ };
