[PATCH v3 1/3] dt-bindings: hwinfo: Add VIA/WonderMedia SoC identification
Posted by Alexey Charkov 9 months, 1 week ago
VIA/WonderMedia SoC's have a chip ID register inside their system
configuration controller space, which can be used to identify
appropriate hardware quirks at runtime. Add binding for it.
