Commit b64a85fb8f ("phy: ti: phy-j721e-wiz.c: Add usxgmii support in
wiz driver") added support for USXGMII mode. In doing so, P0_REFCLK_SEL
was set to "pcs_mac_clk_divx1_ln_0" (0x3) and P0_STANDARD_MODE was set to
LANE_MODE_GEN1, which results in a data rate of 5.15625 Gbps. However,
since the USXGMII mode can support up to 10.3125 Gbps data rate, the
aforementioned fields should be set to "pcs_mac_clk_divx0_ln_0" (0x2) and
LANE_MODE_GEN2 respectively. The signal corresponding to the USXGMII lane
of the SERDES has been measured as 5 Gbps without the change and 10 Gbps
with the change. Hence, fix the configuration accordingly to support
USXGMII up to 10G.

The bit_types array just hold a list of valid enum power_supply_usb_type
values which map to 0 - 9. This can easily be represented as a bitmap.
This reduces the size of struct power_supply_desc and further reduces
the data section size by drivers no longer needing to store the array.
This also unifies how usb_types are handled with charge_behaviours,
which allows power_supply_show_usb_type() to be removed.

Runtime PM is not supported while USB PHY can be turned off from
register accesses.
Add runtime PM for the USB2.0 PHY. The PHY is entirely shut down to save
as much power as possible. This means that gadgets will not be discovered
once suspend state is entered, and suspend state can not be left without
an explicit user intervention (through sysfs). That's why runtime PM is
disabled by default.

The power_supply frame-work is not really designed for there to be
long living in kernel references to power_supply devices.
Specifically unregistering a power_supply while some other code has
a reference to it triggers a WARN in power_supply_unregister():
WARN_ON(atomic_dec_return(&psy->use_cnt));
Folllowed by the power_supply still getting removed and the
backing data freed anyway, leaving the tusb1210 charger-detect code
with a dangling reference, resulting in a crash the next time
tusb1210_get_online() is called.
Fix this by only holding the reference in tusb1210_get_online()
freeing it at the end of the function. Note this still leaves
a theoretical race window, but it avoids the issue when manually
rmmod-ing the charger chip driver during development.

When the node for this phy selector is a child node of a syscon node then the
property 'reg' is used as an offset into the parent regmap. When the node
is standalone and gets its own regmap this offset is pre-applied. So we need
to track which method was used to get the regmap and not apply the offset
in the standalone case.

As part of that merge prepping Arm DT support 13 years ago, they

The TI J721e Wiz clock implements a mux with a set_parent
hook, but doesn't provide a determine_rate implementation.
This is a bit odd, since set_parent() is there to, as its name implies,
change the parent of a clock. However, the most likely candidate to
trigger that parent change is a call to clk_set_rate(), with
determine_rate() figuring out which parent is the best suited for a
given rate.
The other trigger would be a call to clk_set_parent(), but it's far less
used, and it doesn't look like there's any obvious user for that clock.
So, the set_parent hook is effectively unused, possibly because of an
oversight. However, it could also be an explicit decision by the
original author to avoid any reparenting but through an explicit call to
clk_set_parent().
The latter case would be equivalent to setting the flag
CLK_SET_RATE_NO_REPARENT, together with setting our determine_rate hook
to __clk_mux_determine_rate(). Indeed, if no determine_rate
implementation is provided, clk_round_rate() (through
clk_core_round_rate_nolock()) will call itself on the parent if
CLK_SET_RATE_PARENT is set, and will not change the clock rate
otherwise.
And if it was an oversight, then we are at least explicit about our
behavior now and it can be further refined down the line.
Since the CLK_SET_RATE_NO_REPARENT flag was already set though, it seems
unlikely.

TI's J721E SoC supports SGMII mode with the CPSW9G instance of the CPSW
Ethernet Switch. Thus, enable it by adding SGMII mode to the list of the
corresponding extra_modes member.

Add support to configure the CPSW MAC's PHY in SGMII mode if the SoC
supports it. The extra_modes member of the phy_gmii_sel_soc_data struct
corresponding to the SoC is used to determine whether or not the SoC
supports SGMII mode.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Merge tag 'phy-fixes-6.2' into next
Merge fixes tag pulled into mainline by Linus into phy/next due to
dependency on amlogic patches
The WIZ acts as a wrapper for SerDes and has Lanes 0 and 2 reserved
for USB for type-C lane swap if Lane 1 and Lane 3 are linked to the
USB PHY that is integrated into the SerDes IP. The WIZ control register
has to be configured to support this lane swap feature.
The support for swapping lanes 2 and 3 is missing and therefore
add support to configure the control register to swap between
lanes 2 and 3 if PHY type is USB.

It's possible that the Type-C plug orientation on the DIR line will be
implemented through hardware design. In that situation, there won't be
an external GPIO line available, but the driver still needs to address
this since the DT won't use the typec-dir-gpios property.
Add code to handle LN10 Type-C swap if typec-dir-gpios property is not
specified in DT.
