Now that we have some infrastructure for it, allow the MIPI D-PHY phy's to
be configured through the generic functions through a custom structure
added to the generic union.The parameters added here are the ones defined in the MIPI D-PHY spec, plus
the number of lanes in use. The current set of parameters should cover all
the potential users.Signed-off-by: Maxime Ripard

The phy framework is only allowing to configure the power state of the PHY
using the init and power_on hooks, and their power_off and exit
counterparts.While it works for most, simple, PHYs supported so far, some more advanced
PHYs need some configuration depending on runtime parameters. These PHYs
have been supported by a number of means already, often by using ad-hoc
drivers in their consumer drivers.That doesn't work too well however, when a consumer device needs to deal
with multiple PHYs, or when multiple consumers need to deal with the same
PHY (a DSI driver and a CSI driver for example).So we'll add a new interface, through two funtions, phy_validate and
phy_configure. The first one will allow to check that a current
configuration, for a given mode, is applicable. It will also allow the PHY
driver to tune the settings given as parameters as it sees fit.phy_configure will actually apply that configuration in the phy itself.

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based

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.Cc: Kishon Vijay Abraham I

I noticed that phy_pm_runtime_get_sync() and phy_pm_runtime_put() are not
currently doing anything for phy-mapphone-mdm6600, only the sysfs interface
for works for "auto" and "on".This is because of the shared GPIO pins between mdm6600 USB port and n_gsm
port. We have not enabled runtime PM for the phy driver until after we've
booted up mdm6600 properly to the USB mode. Otherwise phy_create() would
have called pm_runtime_enable() and pm_runtime_no_callbacks() automatically
on init.Let's fix this by registering the phy a bit later after we've powered up
the mdm6600 USB port.And as the PM runtime support is only needed for the n_gsm mode and not for
USB, we can allow the device to idle between phy_mdm6600_power_on() and
phy_mdm6600_power_off(). Note that for suspend, runtime_pm is already
disabled for the phy so we need to check for pm_runtime_enabled().Cc: Johan Hovold

Add a Sierra PHY driver with PCIe and USB support.
The PHY has multiple lanes, which can be configured into
groups, and a generic PHY device is created for each group.There are two resets controlling the overall PHY block, one
to enable the APB interface for programming registers, and
another to enable the PHY itself. Additionally there are
resets for each PHY lane.The PHY can be configured in hardware to read register
settings from ROM, or they can be written by the driver.The sequence of operation on startup is to enable the APB
bus, write the PHY registers (if required) for each lane
group, and then enable the PHY. Each group of lanes
can then be individually controlled using the power_on()/
power_off() function for that generic PHYSigned-off-by: Alan Douglas

Add DT binding documentation for Sierra PHY. The PHY supports
a number of different protocols, including PCIe and USB.The PHY lanes may be configured as single or multi-lane links.
Each link is treated as a separate sub-node. For example, if
there are 4 lanes in total the first 2 might be configured as
a multi-lane PCIe link while the other two are single lane
USB links, and in this case there would be 3 sub-nodes.There are two resets for the PHY block (one for APB register
access, one for the PHY link) and separate resets for each
link. For multi-lane links, the reset corresponds to the
reset line on the master lane, the resets on other lanes
have no effect.Signed-off-by: Alan Douglas

Add new PHY's mode to be used by Ethernet PHY interface drivers or

Signed-off-by: Kishon Vijay Abraham I -
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).[1] http://lkml.kernel.org/r/d63588f6-9ab0-848a-5ad4-8073143bd95d@ti.com

Digging through the "phy-qcom-qmp" showed me many inconsistencies
between the bindings and the reality of the driver. Let's fix them
all.* In commit 2d66eab18375 ("dt-bindings: phy: qmp: Add support for QMP
phy in IPQ8074") we probably should have explicitly listed that
there are no clocks for this PHY and also added the reset names in
alphabetical order. You can see that there are no clocks in the
driver where "clk_list" is NULL.* In commit 8587b220f05e ("dt-bindings: phy-qcom-qmp: Update bindings
for QMP V3 USB PHY") we probably should have listed the resets for
this new PHY and also removed the "(Optional)" marking for the "cfg"
reset since PHYs that need "cfg" really do need it. It's just that
not all PHYs need it.* In commit 7f0802074120 ("dt-bindings: phy-qcom-qmp: Update bindings
for sdm845") we forgot to update one instance of the string
"qcom,qmp-v3-usb3-phy" to be "qcom,sdm845-qmp-usb3-phy". Let's fix
that. We should also have added "qcom,sdm845-qmp-usb3-uni-phy" to
the clock-names and reset-names lists.* In commit 99c7c7364b71 ("dt-bindings: phy-qcom-qmp: Add UFS phy
compatible string for sdm845") we should have added the set of
clocks and resets for "qcom,sdm845-qmp-ufs-phy". These were taken
from the driver.* Cleanup the wording for what properties child nodes have to make it
more obvious which types of PHYs need clocks and resets. This was
sorta implicit in the "-names" description but I found myself
confused.* As per the code not all "pcie qmp phys" have resets. Specifically
note that the "has_lane_rst" property in the driver is false for
"ipq8074-qmp-pcie-phy". Thus make it clear exactly which PHYs need
child nodes with resets.Signed-off-by: Douglas Anderson
