235Stratix10 SoCFPGA ECC Manager
236The Stratix10 SoC ECC Manager handles the IRQs for each peripheral
237in a shared register similar to the Arria10. However, ECC requires
238access to registers that can only be read from Secure Monitor with
239SMC calls. Therefore the device tree is slightly different.
240
241Required Properties:
242- compatible : Should be "altr,socfpga-s10-ecc-manager"
243- interrupts : Should be single bit error interrupt, then double bit error
244 interrupt.
245- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
246- #interrupt-cells : must be set to 2.
247
248Subcomponents:
249
250SDRAM ECC
251Required Properties:
252- compatible : Should be "altr,sdram-edac-s10"
253- interrupts : Should be single bit error interrupt, then double bit error
254 interrupt, in this order.
