The space is typically meant to be +owned by platform management software, and this space is accessible only when +the platform management software grants the access. Thus, this dt binding only +works in such configuration, and in case the platform locks the access, +the non-secure software fails to access the device. + +This is a temporary solution to allow direct access to NPI space. + +Required properties: + +- compatible: Must be "xlnx,ai-engine-npi" +- reg: Physical base address and length of the registers set for the device. + +Example: + + aie-npi@f70a0000 { + compatible = "xlnx,ai-engine-npi"; + reg = <0x0 0xf70a0000 0x0 0x1000>; + }; |
