Some Qualcomm PMICs integrate an USB Repeater device, used to
convert between eUSB2 and USB 2.0 signaling levels, reachable
in a specific address range over SPMI.
Instead of using the parent SPMI device (the main PMIC) as a kind
of syscon in this driver, register a new SPMI sub-device for EUSB2
and initialize its own regmap with this sub-device's specific base
address, retrieved from the devicetree.
This allows to stop manually adding the register base address to
every R/W call in this driver, as this can be, and is now, handled
by the regmap API instead.

The driver reads the active link mode through
syscon_regmap_lookup_by_phandle_args(). Without CONFIG_MFD_SYSCON the
stub returning -ENOTSUPP is compiled in instead, so probe fails for
every device and no PHY is ever registered.
Nothing in the build catches this: the driver still compiles, and arm64
defconfig happens to enable MFD_SYSCON through an unrelated select.

Add a new MIPI CSI2 driver in DPHY mode initially. The entire set of
existing CAMSS CSI PHY init sequences are imported in order to save time
and effort in later patches.
The following devices are supported in this drop:
"qcom,x1e80100-csi2-phy"
In-line with other PHY drivers the process node is included in the name.
Data-lane and clock lane positioning and polarity selection via newly
amended struct phy_configure_opts_mipi_dphy{} is supported.
The Qualcomm 3PH class of PHYs can do both DPHY and CPHY mode. For now only
DPHY is supported.
In porting some of the logic over from camss-csiphy*.c to here its also
possible to rationalise some of the code.
In particular use of regulator_bulk and clk_bulk as well as dropping the
seemingly useless and unused interrupt handler.
The PHY sequences and a lot of the logic that goes with them are well
proven in CAMSS and mature so the main thing to watch out for here is how
to get the right sequencing of regulators, clocks and register-writes.
The register init sequence table is imported verbatim from the existing
CAMSS csiphy driver. A follow-up series will rework the table to extract
the repetitive per-lane pattern into a loop.

Some QMP PCIe PHY hardware blocks support multiple link topologies (e.g.
x8 or x4+x4) selected via a TCSR register. The existing single-instance
QMP PCIe PHY driver has no way to model this: it assumes a single cfg per
DT node and instantiates exactly one PHY.
Add a dedicated driver for this class of PHY. Match data carries a
per-mode cfg table; qmp_pcie_multiphy_probe() reads the current link
mode from the TCSR register pointed to by "qcom,link-mode", looks up the
corresponding cfg array, and instantiates one qmp_pcie per sub-PHY
required by that link mode, registering the clock and #phy-cells = <1> phy
providers so consumers can address individual sub-PHYs by index.
The driver inherits the phy setting and link-mode programmed by firmware,
so only the no_csr reset is used and no phy setting tables are provided.
Add the first match data and compatible, qcom,glymur-qmp-gen5x8-pcie-phy,
for the Glymur Gen5 PCIe PHY that can bifurcate into two x4 links or
operate as a single x8 link.

SM8750 utilizes an eUSB2 PHY from M31. Add the initialization
sequences to bring it out of reset and into an operational state. This
differs to the M31 USB driver, in that the M31 eUSB2 driver will
require a connection to an eUSB2 repeater. This PHY driver will handle
the initialization of the associated eUSB2 repeater when required.

The QMP combo PHY sits in an of_graph connected between the DisplayPort
controller and a USB Type-C connector (or possibly a redriver).
The TCPM needs to be able to convey the HPD signal to the DisplayPort
controller, but no directly link is provided by DeviceTree so the signal
needs to "pass through" the QMP combo phy.
Handle this by introducing a drm_bridge which upon initialization finds
the next bridge (i.e. the usb-c-connector) and chain this together. This
way HPD changes in the connector will propagate to the DisplayPort
driver.
The connector bridge is resolved lazily, as the TCPM is expected to be
able to resolve the typec mux and switch at probe time, so the QMP combo
phy will probe before the TCPM.

The data lanes of the QMP PHY is swapped in order to handle changing
orientation of the USB Type-C cable. Register a typec_switch device to
allow a TCPM to configure the orientation.
The newly introduced orientation variable is adjusted based on the
request, and the initialized components are brought down and up again.
To keep track of what parts needs to be cycled new variables to keep
track of the individual init_count is introduced.
Both the USB and the DisplayPort altmode signals are properly switched.
For DisplayPort the controller will after the TCPM having established
orientation power on the PHY, so this is not done implicitly, but for
USB the PHY typically is kept initialized across the switch, and must
therefore then be reinitialized.
This is based on initial work by Wesley Cheng.

Introduce a config option for each QMP PHY driver now that the QMP PHY
mega-driver has been split up into different modules. This allows kernel
configurators to limit the binary size of the kernel by only compiling
in the QMP PHY driver that they need.
Leave the old config QCOM_QMP in place and make it into a menuconfig so
that 'make olddefconfig' continues to work. Furthermore, set the default
of the new Kconfig symbols to be QCOM_QMP so that the transition is
smooth.

Many recent Qualcomm platforms comes with native DP and eDP support.
This consists of a controller in the MDSS and a QMP-like PHY.
While similar to the well known QMP block, the eDP PHY only has TX lanes
and the programming sequences are slightly different. Rather than
continuing the trend of parameterize the QMP driver to pieces, this
introduces the support as a new driver.
The registration of link and pixel clocks are borrowed from the QMP
driver. The non-DP link frequencies are omitted for now.
The eDP PHY is very similar to the dedicated (non-USB) DP PHY, but only
the prior is supported for now.

Controls Qualcomm's SS PHY 1.0.0 implemented on various SoCs on both the
20nm and 28nm process nodes.
Based on Sriharsha Allenki's <sallenki@codeaurora.org> original code.
[bod: Removed dependency on extcon.
Switched to gpio-usb-conn to handle VBUS On/Off
Switched to usb-role-switch to bind gpio-usb-conn to DWC3]

Adds Qualcomm 28nm Hi-Speed USB PHY driver support. This PHY is usually
paired with Synopsys DWC3 USB controllers on Qualcomm SoCs.
The PHY can come in two flavours femtoPHY or picoPHY. This commit adds
support for the femtoPHY with the possibility of extending to the picoPHY
with additional future commits. Both PHYs are on a 28 nanometer process
node.
[bod: Updated qcom_snps_hsphy_set_mode to match new method signature
Added disjunct on mode > 0
Removed regulator_set_voltage() in favour of setting floor in dts
Removed 'snps' and from driver name
Extended commit log to mention femtoPHY and picoPHY for future
reference.]

The ATH79 USB phy is very simple, it only have a reset. On some SoC a
second reset is used to force the phy in suspend mode regardless of the
USB controller status.
This driver is added to the qualcom directory as atheros is now part
of qualcom and newer SoC of this familly are marketed under the
qualcom name.
