* Serial NOR flash controller for MTK MT81xx (and similar)
Required properties:
- compatible: The possible values are:
"mediatek,mt2701-nor"
"mediatek,mt7623-nor"
- compatible: For mt8173, compatible should be "mediatek,mt8173-nor",
and it's the fallback compatible for other Soc.
For every other SoC, should contain both the SoC-specific compatible
string and "mediatek,mt8173-nor".
The possible values are:
"mediatek,mt2701-nor", "mediatek,mt8173-nor"
"mediatek,mt2712-nor", "mediatek,mt8173-nor"
"mediatek,mt7622-nor", "mediatek,mt8173-nor"
"mediatek,mt7623-nor", "mediatek,mt8173-nor"
"mediatek,mt8173-nor"
For mt8173, compatible should be "mediatek,mt8173-nor".
For every other SoC, should contain both the SoC-specific compatible string
and "mediatek,mt8173-nor".
- reg: physical base address and length of the controller's register
- clocks: the phandle of the clocks needed by the nor controller
- clock-names: the names of the clocks
