phy: ti: usb2: Fix logic on -EPROBE_DEFER

2019-02-07T05:40:37+00:00

If clk_get() returns -EPROBE_DEFER then we should just
return instead of falling back to old clock name.

Use clk_prepare_enable() and clk_disable_unprepare() instead
of splitting up prepare/unprepare from enable/disable.

phy: ti: ensure priv is not null before dereferencing it

2019-01-16T12:30:54+00:00

Currently priv is being dereferenced before priv is being null checked.
Fix this by moving the null check on priv before the dereference.

phy: ti: introduce phy-gmii-sel driver

2018-12-12T04:31:40+00:00

TI am335x/am437x/dra7(am5)/dm814x CPSW3G Ethernet Subsystem supports two
10/100/1000 Ethernet ports with selectable G/MII, RMII, and RGMII
interfaces. The interface mode is selected by configuring the MII mode
selection register(s) (GMII_SEL) in the System Control Module chapter
(SCM). GMII_SEL register(s) and bit fields placement in SCM are different
between SoCs while fields meaning is the same.

Historically CPSW external Port's interface mode selection configuration
was introduced using custom API and driver cpsw-phy-sel.c. This leads to
unnecessary driver, DT binding and custom API support effort.

This patch introduces CPSW Port's PHY Interface Mode selection Driver
(phy-gmii-sel) which implements standard Linux PHY interface and used
as a replacement for TI's specific driver cpsw-phy-sel.c and corresponding
custom API.

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).
