| description: | |
| Hisilicon HiP06 SoCs implement a Low Pin Count (LPC) controller, which |
| provides I/O access to some legacy ISA devices. |
| HiP06 is based on arm64 architecture where there is no I/O space. So, the |
| I/O ports here are not CPU addresses, and there is no 'ranges' property in |
| LPC device node. |
| |
| properties: |
| $nodename: |
| pattern: '^isa@[0-9a-f]+$' |
| description: | |
| The node name before '@' must be "isa" to represent the binding stick |
| to the ISA/EISA binding specification. |
