During the introduction of the Allwinner SoC platforms, sunxi was initially meant as a generic name for all the variants of the Allwinner SoC. It was ok at the time of the support of only the A10 and A13 that looks pretty much the same, but it's beginning to be troublesome with the future addition of the Allwinner A31 (sun6i) that is quite different, and would introduce some weird logic, where sunxi would actually mean in some case sun4i and sun5i but without sun6i... Moreover, it makes the compatible strings naming scheme not consistent with other architectures, where usually for this kind of compability, we just use the oldest SoC name that has this IP, so let's do just this.

Allwinner Sunxi Interrupt Controller
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "allwinner,sun4i-ic"
|
|
- reg : Specifies base physical address and size of the registers.
|
|
- interrupt-controller : Identifies the node as an interrupt controller
|
|
- #interrupt-cells : Specifies the number of cells needed to encode an
|
|
interrupt source. The value shall be 1.
|
