Since commit 88d26136a2 ("PM: Prevent runtime suspend during system
resume"), PM runtime will not let devices idle during system suspend.
This is because of the pm_runtime_get_noresume() call done in
device_prepare() that is not released until at device_complete() after
resume.
We must now disable the USB PHY in suspend if no USB cable is connected.

The current driver uses a value from register TEST_O as the original
value for register TEST_I, though, the value is overwritten by "param",
so there is a bug that the original value isn't no longer used.
The value of TEST_O[7:0] should be masked with "mask", replaced with
"param", and placed in the bitfield TESTI_DAT_MASK as new TEST_I value.

The driver adds support for generic CAN transceivers. Currently
the modes supported by this driver are standby and normal modes for TI
TCAN1042 and TCAN1043 CAN transceivers.
The transceiver is modelled as a phy with pins controlled by gpios, to put
the transceiver in various device functional modes. It also gets the phy
attribute max_link_rate for the usage of CAN drivers.

To support XUSB host controller ELPG, this commit moves VBUS control
.phy_power_on()/.phy_power_off() to .phy_init()/.phy_exit().
When XUSB host controller enters ELPG, host driver invokes
.phy_power_off(), VBUS should remain ON so that USB devices will not
disconnect. VBUS can be turned OFF when host driver invokes
.phy_exit() which indicates disabling a USB port.

This commit is a preparation for enabling XUSB SC7 support.
It rearranges Tegra210 XUSB PADCTL UPHY initialization sequence,
for the following reasons:
1. PLLE hardware power sequencer has to be enabled only after both
PEX UPHY PLL and SATA UPHY PLL are initialized.
tegra210_uphy_init() -> tegra210_pex_uphy_enable()
-> tegra210_sata_uphy_enable()
-> tegra210_plle_hw_sequence_start()
-> tegra210_aux_mux_lp0_clamp_disable()
2. At cold boot and SC7 exit, the following bits must be cleared after
PEX/SATA lanes are out of IDDQ (IDDQ_DISABLE=1).
a. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN,
b. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_CLAMP_EN_EARLY
c. XUSB_PADCTL_ELPG_PROGRAM1_AUX_MUX_LP0_VCORE_DOWN
tegra210_pex_uphy_enable() and tegra210_sata_uphy_enable() are in
charge of bringing lanes out of IDDQ, and then AUX_MUX_LP0_* bits
will be cleared by tegra210_aux_mux_lp0_clamp_disable().
3. Once UPHY PLL hardware power sequencer is enabled, do not assert
reset to PEX/SATA PLLs, otherwise UPHY PLL operation will be broken.

walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection

- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original

- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR

accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs

current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)

policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)

programs access to task local storage previously added for
BPF_LSM

parsing scripts we already employ for bpf-helpers

- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks

performance of software AF_XDP path by 33% for devices which don't
need headers in the linear skb part (e.g. virtio)

- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is slow in
reporting that it completed transmitting the original

- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR

co-existence with UDP tunnel GRO, allowing the first to take place
correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls

before handing them off to routing, bridge, OvS, etc.

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.

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. Model this derived reference clock as a "clock" so that
platforms like AM642 EVM can enable it.
This is used by PCIe to use the same refclk both in local SERDES
and remote device. Add support here to drive refclk out.

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.

port configuration independently from the boot loader setup.
The CP110/CP115 dies have 2 UTMI PHYs that could be connected
to two USB host controllers or to single USB device controller.
Since there is only one USB device controller on die, only one
of the UTMI PHYs could work in USB device mode.

USBPHYC has a register per phy to control and monitor the debug interface
of the HS PHY through a digital debug access.
With this register, it is possible to know if PLL Lock input to phy is
high. That means the PLL is ready for HS operation.
Instead of using an hard-coded delay after PLL enable and PLL disable, use
this bit to ensure good operating of the HS PHY.
Also use an atomic counter (n_pll_cons) to count the actual number of PLL
consumers and get rid of stm32_usbphyc_has_one_phy_active.
The boolean active in the usbphyc_phy structure is kept, because we need to
know in remove if a phy_exit is required to properly disable the PLL.
