1	Altera SoCFPGA ECC Manager
2	This driver uses the EDAC framework to implement the SOCFPGA ECC Manager.
3	The ECC Manager counts and corrects single bit errors and counts/handles
4	double bit errors which are uncorrectable.
5	
6	Cyclone5 and Arria5 ECC Manager
7	Required Properties:
8	- compatible : Should be "altr,socfpga-ecc-manager"
9	- #address-cells: must be 1
10	- #size-cells: must be 1
11	- ranges : standard definition, should translate from local addresses
12	
13	Subcomponents:
14	
15	L2 Cache ECC
16	Required Properties:
17	- compatible : Should be "altr,socfpga-l2-ecc"
18	- reg : Address and size for ECC error interrupt clear registers.
19	- interrupts : Should be single bit error interrupt, then double bit error
20		interrupt. Note the rising edge type.
21	
22	On Chip RAM ECC
23	Required Properties:
24	- compatible : Should be "altr,socfpga-ocram-ecc"
25	- reg : Address and size for ECC error interrupt clear registers.
26	- iram : phandle to On-Chip RAM definition.
27	- interrupts : Should be single bit error interrupt, then double bit error
28		interrupt. Note the rising edge type.
29	
30	Example:
31	
32		eccmgr: eccmgr@ffd08140 {
33			compatible = "altr,socfpga-ecc-manager";
34			#address-cells = <1>;
35			#size-cells = <1>;
36			ranges;
37	
38			l2-ecc@ffd08140 {
39				compatible = "altr,socfpga-l2-ecc";
40				reg = <0xffd08140 0x4>;
41				interrupts = <0 36 1>, <0 37 1>;
42			};
43	
44			ocram-ecc@ffd08144 {
45				compatible = "altr,socfpga-ocram-ecc";
46				reg = <0xffd08144 0x4>;
47				iram = <&ocram>;
48				interrupts = <0 178 1>, <0 179 1>;
49			};
50		};
51	
52	Arria10 SoCFPGA ECC Manager
53	The Arria10 SoC ECC Manager handles the IRQs for each peripheral
54	in a shared register instead of individual IRQs like the Cyclone5
55	and Arria5. Therefore the device tree is different as well.
56	
57	Required Properties:
58	- compatible : Should be "altr,socfpga-a10-ecc-manager"
59	- altr,sysgr-syscon : phandle to Arria10 System Manager Block
60		containing the ECC manager registers.
61	- #address-cells: must be 1
62	- #size-cells: must be 1
63	- interrupts : Should be single bit error interrupt, then double bit error
64		interrupt.
65	- interrupt-controller : boolean indicator that ECC Manager is an interrupt controller
66	- #interrupt-cells : must be set to 2.
67	- ranges : standard definition, should translate from local addresses
68	
69	Subcomponents:
