Hi Andrew,
and where (into which directory) should this serdes.yaml file go?
My idea was to put the properties into common PHY and then refer to
them from other places, so for example this would be put into ethernet
PHY binding:
serdes-tx-amplitude-microvolt:
$ref: '/schemas/phy/phy.yaml#/properties/tx-amplitude-microvolt'
