It is still not clear to me why is not the parsing being done by
the PHY
library helper directly?
Why would we do that for these properties and not any other?
Those properties have a standard name, which makes them suitable for
parsing by the core PHY library.
Unless there is a new precedence being set here by having the PHY
framework do all the dt node parsing for common properties.
You could parse the vendor properties through the driver, let the PHY
library parse the standard properties, and resolve any ordering
precedence within the driver. In general, I would favor standard
properties over vendor properties.
Does this help?
Ok so new precedence then.
Because there are common properties like tx-fifo-depth, rx-fifo-depth,
enet-phy-lane-swap and max_speed that the PHY framework should parse
as well.
I am assuming that the retrieval of the property and getting the index
should be 2 separate APIs?
One API to get the property value and one API to find the index value.
