Subject: [PATCH v2 0/5] phy: core: rework phy_set_mode to accept phy mode and submode

Hi Kishon, All,

As was discussed in [1] I'm posting series which introduces rework of
phy_set_mode to accept phy mode and submode. I've dropped TI specific patches as
this change is pretty big by itself.

Patch 1 is cumulative change which refactors PHY framework code to
support dual level PHYs mode configuration - PHY mode and PHY submode. It
extends .set_mode() callback to support additional parameter "int submode"
and converts all corresponding PHY drivers to support new .set_mode()
callback declaration.
The new extended PHY API
 int phy_set_mode_ext(struct phy *phy, enum phy_mode mode, int submode)
is introduced to support dual level PHYs mode configuration and existing
phy_set_mode() API is converted to macros, so PHY framework consumers do
not need to be changed (~21 matches).

Patches 2-4: Add new PHY's mode to be used by Ethernet PHY interface drivers or
multipurpose PHYs like serdes and convert ocelot-serdes and mvebu-cp110-comphy
PHY drivers to use recently introduced PHY_MODE_ETHERNET and phy_set_mode_ext().

Patch 5 - removes unused, ethernet specific phy modes from enum phy_mode.

Testing:
 - series tested on TI am335x/am437x/am5(dra7) paltforms.
 - other driver build tested.

changes in v2:
- marvell PHY and net drivers updated as recommended by Russell King
