Each of the CPSW5G ports in J7200 support additional modes like QSGMII.
Add a new compatible for J7200 to support the additional modes.
In TI's J7200, each of the CPSW5G ethernet interfaces can act as a
QSGMII or QSGMII-SUB port. The QSGMII interface is responsible for
performing auto-negotiation between the MAC and the PHY while the rest of
the interfaces are designated as QSGMII-SUB interfaces, indicating that
they will not be taking part in the auto-negotiation process.
To indicate the interface which will serve as the main QSGMII interface,
add a property "ti,qsgmii-main-ports", whose value indicates the
port number of the interface which shall serve as the main QSGMII
interface. The rest of the interfaces are then assigned QSGMII-SUB mode by
default. The property "ti,qsgmii-main-ports" is used to configure the
CTRLMMR_ENETx_CTRL register.
Depending on the device, it is possible for more than one QSGMII main port
to exist. Thus, the property "ti,qsgmii-main-ports" is defined as an array
of values in order to reuse the property for other devices.

For J7200-SR2.0 and AM64 we don't model Common refclock divider as
a clock divider as the divisor rate is fixed based on operating
reference clock frequency. We just program the recommended value
into the register. This simplifies the device tree and implementation
a lot.

Some Android x86 tablets with a Bay Trail (BYT) SoC and a Crystal Cove
PMIC, which does not support charger-detection, rely on a TUSB1211
phy for charger-detection.
Add support for charger detection on TUSB1211 phy-s and export
the information about the detected charger through the standard
power_supply class interface. power_supply class charger IC drivers
like the bq24190_charger.c driver will then pick this up and set
their input_current_limit based on this.
Note the "linux,phy_charger_detect" property used to enable this is
a special kernel-internal (so not part of the dt-bindings) property
used by dwc3 platform code to indicate that the phy needs to do
charger-detection.
Changes by Hans de Goede:
- Use "linux,phy_charger_detect" property to enable charger-detect
- Switch from a linear flow to a state-machine, with retries on
ulpi communication errors
- Use SW_CONTROL bit to disable the FSM when detection is finished
- Do a phy-reset on disconnect to work around the phy often refusing
ulpi_read()/_write() commands after a disconnect
- Use power_supply_reg_notifier() for Vbus monitoring
- Export the detection result through a power_supply class device

This driver's remove path calls cancel_delayed_work(). However, that
function does not wait until the work function finishes. This means
that the callback function may still be running after the driver's
remove function has finished, which would result in a use-after-free.
Fix by calling cancel_delayed_work_sync(), which ensures that
the work is properly cancelled, no longer running, and unable
to re-schedule itself.

Serdes lanes might be shared between multiple cores in some usecases
and its not possible to lock PLLs for both the lanes independently
by the two cores. This requires a bootloader to configure both the
lanes at early boot time.
To handle this case, skip all configuration if any of the lanes has
already been enabled.

"serdes" node (child node of WIZ) can have sub-nodes for representing links
or it can have sub-nodes for representing the various clocks within the
serdes. Instead of trying to read "reg" from every child node used for
assigning "lane_phy_type", read only if the child node's name is "phy"
or "link" subnode.
Ideally all PHY dt nodes should have node name as "phy", however
existing devicetree used "link" as subnode. So in order to maintain old
DT compatibility get PHY properties for "phy" or "link" subnode.

Invoke wiz_init() before configuring anything else in Sierra/Torrent
(invoked as part of of_platform_device_create()). wiz_init() resets the
SERDES device and any configuration done in the probe() of
Sierra/Torrent will be lost. In order to prevent SERDES configuration
from getting reset, invoke wiz_init() immediately before invoking
of_platform_device_create().

cmn_refclk_<p/m> lines in Torrent SERDES is used for connecting external
reference clock. cmn_refclk_<p/m> can also be configured to output the
reference clock. In order to drive the refclk out from the SERDES
(Cadence Torrent), PHY_EN_REFCLK should be set in SERDES_RST of WIZ.
Model PHY_EN_REFCLK as a clock, so that platforms like AM642 EVM can
enable it.

commit 091876cc35 ("phy: ti: j721e-wiz: Add support for WIZ module
present in TI J721E SoC") modeled the internal clocks depending on the
subnodes that are populated in device tree. However recent discussions
in the mailing list [1] suggested to just add #clock cells in the parent
DT node and model the clocks within the driver.
Model the mux clocks without device tree input for AM64x SoC. Don't
remove the earlier design since DT nodes for J7200 and J721e are already
upstreamed.

Both "struct wiz_clk_div_sel" and "struct wiz_clk_mux_sel" are static
data that is common for all wiz instances. Including
"struct regmap_field" for each of the wiz instances can yield undesirable
results. Move "struct regmap_field" out of "struct wiz_clk_div_sel" and
"struct wiz_clk_mux_sel" and make them point to constant data.
So far no issues are observed since both these structures are not
accessed outside the probe.

Start by reading the content of the VENDOR_SPECIFIC2 register and update
each bit field based on device properties when defined.
The use of bit masks prevents fields from overriding each other and
enables users to clear bits which are set by default, like datapolarity
in this instance.
