Message

QCA8084 is four-port PHY with maximum link capability 2.5G,
which supports the interface mode qusgmii and sgmii mode,
there are two PCSs available to connected with ethernet port.

QCA8084 can work in switch mode or PHY mode.
For switch mode, both PCS0 and PCS1 work on sgmii mode.
For PHY mode, PCS1 works on qusgmii mode.
The fourth PHY connected with PCS0 works on sgmii mode.

Besides this PHY driver patches, the PCS driver is also needed
to bring up the qca8084 device, which mainly configurs PCS
and clocks.

The qca8084 PHY driver depends on the following clock controller
patchset, the initial clocks and resets are provided by the clock
controller driver below.

Changes in v3:
	* pick the two patches to introduce the interface mode
	  10g-qxgmii from Vladimir Oltean([e-mail]).
	* add the function phydev_id_is_qca808x to identify the
	  PHY qca8081 and qca8084.
	* update the interface mode name PHY_INTERFACE_MODE_QUSGMII
	  to PHY_INTERFACE_MODE_10G_QXGMII.

Changes in v4:
	* remove the following patch:
	  <net: phylink: move phylink_pcs_neg_mode() to phylink.c>.
	* split out 10g_qxgmii change of ethernet-controller.yaml.

Changes in v5:
	* update the author of the patch below.
	  <introduce core support for phy-mode = "10g-qxgmii">.

Changes in v6:
	* drop the "inline" keyword.
	* apply the patches with "--max-line-length=80".

Changes in v7:
	* add possible interfaces of phydev
	* customize phy address
	* add initialized clock & reset config
	* add the work mode config
	* update qca,ar803x.yaml for the new added properties

Changes in v7:
	* updated the patcheset based on the latest code
