Subject: [net-next RFC PATCH 0/6] net: phy: support multi PHY in phy_driver Was: net: phy: detach PHY driver OPs from phy_driver struct
This is an alternative implementation of "net: phy: detach PHY driver OPs
from phy_driver struct" with the same object in mind.
As was pointed out in the previous series, deatching OPs is a way too big
change (although IMHO needed, but I understand the problem with downstream
and ugly code). As suggested and was already an idea discussed privately,
a more easier approach is introduce an alternative way in phy_driver
struct to declare PHY with the use of an array of IDs.
Some small changes were needed to mod_devicetable to make mdio_device_id
more suitable for the task.
This implementation keep the single way to declare PHY ID in phy_driver
but also indotruce .ids where a table of mdio_device_id can be defined.
Each entry can optionally have a .name variable to define a more specific
PHY name (for phydev_info/err.. usage) that if detected will overwrite
the dev name.
An example of this name is a phy_driver with a .name "Aquantia 107/102"
and .ids with single mdio_device_id with "Aquantia 107" and "Aquantia 102"
"Aquantia 107/102" will be used for early PHY driver probe and the more
specific name will be used as soon as the phydev dev_id is populated.
Aquantia driver is reworked to this implementation and BCM7xxx driver
table is rewritten to greatly benefits from this implementation.
While at it I also notice a strange problem with detected PHY ID and
C45 PHYs. Probably i will have to drop it, but including in this series
just to make someone aware and maybe discuss about it too?
Christian Marangi (6):
net: phy: add support for defining multiple PHY IDs in PHY driver
net: phy: fill phy_id with C45 PHY
mod_devicetable: permit to define a name for an mdio_device_id
net: phy: support named mdio_device_id PHY IDs
net: phy: aquantia: group common OPs for PHYs where possible
net: phy: bcm7xxx: rework phy_driver table to new multiple PHY ID
