[PATCH v3 1/3] net: phy: Remove TI DP83822 from DP83848 driver

[Dan Murphy]

Removing the DP83822 device from the DP83848 to
support the TI DP83822 dedicated driver that will
initially support WoL settings.

[PATCH v3 2/3] net: phy: DP83822 initial driver submission

[Dan Murphy]

Add support for the TI  DP83822 10/100Mbit ethernet phy.

The DP83822 provides flexibility to connect to a MAC through a
standard MII, RMII or RGMII interface.

v3 - Fixed WoL indication bit and removed mutex for suspend/resume - 
https://www.mail-archive.com/netdev@vger.kernel.org/msg191891.html and
https://www.mail-archive.com/netdev@vger.kernel.org/msg191665.html

v2 - Updated per comments.  Removed unnessary parantheis, called genphy_suspend/
resume routines and then performing WoL changes, reworked sopass storage and reduced
the number of phy reads, and moved WOL_SECURE_ON -

Hi Dan,

The ordering of patch 1 and 2 may have to be reversed, otherwise you are
leaving people with the Generic PHY driver matching the DP83822 PHY
after applying patch 1, and without proper interrupt management again
unless they apply patch 2.

It may even be better to combine patch 1 and 2 actually to have a
cleaner transition.

Sorry for noticing this so late in the series...

No worries I will squash patch 1 and 2.
