-Stratix10 SoCFPGA ECC Manager
+Stratix10 SoCFPGA ECC Manager (ARM64)
The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
-in a shared register similar to the Arria10. However, ECC requires
-access to registers that can only be read from Secure Monitor with
-SMC calls. Therefore the device tree is slightly different.
+in a shared register similar to the Arria10. However, Stratix10 ECC
+requires access to registers that can only be read from Secure Monitor
+with SMC calls. Therefore the device tree is slightly different. Note
+that only 1 interrupt is sent in Stratix10 because the double bit errors
+are treated as SErrors in ARM64 instead of IRQs in ARM32.
Required Properties:
- compatible : Should be "altr,socfpga-s10-ecc-manager"
-- interrupts : Should be single bit error interrupt, then double bit error
- interrupt.
+- altr,sysgr-syscon : phandle to Stratix10 System Manager Block
+ containing the ECC manager registers.
+- interrupts : Should be single bit error interrupt.
- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
- #interrupt-cells : must be set to 2.
+- #address-cells: must be 1
+- #size-cells: must be 1
+- ranges : standard definition, should translate from local addresses
Subcomponents:
SDRAM ECC
Required Properties:
- compatible : Should be "altr,sdram-edac-s10"
-- interrupts : Should be single bit error interrupt, then double bit error
- interrupt, in this order.
+- interrupts : Should be single bit error interrupt.
+
+On-Chip RAM ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-ocram-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent OCRAM node.
+- interrupts : Should be single bit error interrupt.
+
+Ethernet FIFO ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-eth-mac-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent Ethernet node.
+- interrupts : Should be single bit error interrupt.
+
+NAND FIFO ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-nand-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent NAND node.
+- interrupts : Should be single bit error interrupt.
+
+DMA FIFO ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-dma-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent DMA node.
+- interrupts : Should be single bit error interrupt.
+
+USB FIFO ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-usb-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent USB node.
+- interrupts : Should be single bit error interrupt.
+
+SDMMC FIFO ECC
+Required Properties:
+- compatible : Should be "altr,socfpga-s10-sdmmc-ecc"
+- reg : Address and size for ECC block registers.
+- altr,ecc-parent : phandle to parent SD/MMC node.
+- interrupts : Should be single bit error interrupt for port A
+ and then single bit error interrupt for port B.
