phy: fix build breakage: add PHY_MODE_SATA

2019-01-13T05:07:14+00:00

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.

Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.

Fix the build by:

    1) Renaming Marvell's defined value to a more scoped name,
       in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.

    2) Adding the missing enum, which was going to be added anyway as part
       of [1].

phy: mvebu-cp110-comphy: fix spelling in structure name

2018-12-12T04:31:39+00:00

Rename the mvebu_comhy_conf structure to be mvebu_comphy_conf, which is
probably what the original author meant.

Convert mvebu-cp110-comphy PHY driver to use recently introduced
PHY_MODE_ETHERNET and phy_set_mode_ext().

phy: core: rework phy_set_mode to accept phy mode and submode

2018-12-12T04:31:33+00:00

Currently the attempt to add support for Ethernet interface mode PHY
(MII/GMII/RGMII) will lead to the necessity of extending enum phy_mode and
duplicate there values from phy_interface_t enum (or introduce more PHY
callbacks) [1]. Both approaches are ineffective and would lead to fast
bloating of enum phy_mode or struct phy_ops in the process of adding more
PHYs for different subsystems which will make them unmaintainable.

As discussed in [1] the solution could be to introduce dual level PHYs mode
configuration - PHY mode and PHY submode. The PHY mode will define generic
PHY type (subsystem - PCIE/ETHERNET/USB_) while the PHY submode - subsystem
specific interface mode. The last is usually already defined in
corresponding subsystem headers (phy_interface_t for Ethernet, enum
usb_device_speed for USB).

This patch 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).

phy: berlin-usb: adjust USB_PHY_RX_CTRL init flags

2018-03-16T08:10:43+00:00

Make the value written into the USB_PHY_RX_CTRL configuration register
match 0xAA79 value written by manufacturer-supplied kernels for Sony
NSZ-GS7 (Berlin2 SoC), Google Chromecast and Valve Steam Link (BG2CD).

This fixes timeouts communicating to the internal hub on Steam Link.
