Linus Torvalds 5c904c66ed Char/Misc driver update for 5.16-rc1
Here is the big set of char and misc and other tiny driver subsystem
 updates for 5.16-rc1.
 
 Loads of things in here, all of which have been in linux-next for a
 while with no reported problems (except for one called out below.)
 
 Included are:
 	- habanana labs driver updates, including dma_buf usage,
 	  reviewed and acked by the dma_buf maintainers
 	- iio driver update (going through this tree not staging as they
 	  really do not belong going through that tree anymore)
 	- counter driver updates
 	- hwmon driver updates that the counter drivers needed, acked by
 	  the hwmon maintainer
 	- xillybus driver updates
 	- binder driver updates
 	- extcon driver updates
 	- dma_buf module namespaces added (will cause a build error in
 	  arm64 for allmodconfig, but that change is on its way through
 	  the drm tree)
 	- lkdtm driver updates
 	- pvpanic driver updates
 	- phy driver updates
 	- virt acrn and nitr_enclaves driver updates
 	- smaller char and misc driver updates

SC8180X PCIe tables, but used sm8250_qmp_pcie_serdes_tbl as a serdes
table because of the copy paste error. Commit bfccd9a71a ("phy:

by pointing serdes_tbl to sc8180x_qmp_pcie_serdes_tbl, however the
serdes_tbl_num field was not updated to use sc8180x table. So let's now
fix the serdes_tbl_num field too.

This patch adds support of new optional properties to configure the tune
interface of the phys of stm32-usbphyc.
Properties are optional, that's why each property is skipped if not
found (-EINVAL).
Phy tuning is restored on resume because if deep low power state is

Add the tables and constants for init sequences for UFS QMP phy found in
SM4250/6115 SoC. The phy is a variation of the v2 phy, but is mistakenly
labeled as v3-660 in downstream sources.

QSERDES COM, RX, TX registers match fully existing v2 registers, with
a few additions. PCS registers don't have much in common, but there are
no clashes with existing ones so new registers were added to existing v2
PCS pack.

Bjorn Andersson 34633219b8 phy: qmp: Provide unique clock names for DP clocks
The USB/DP combo PHY exposes the "qmp_dp_phy_pll_link_clk" and
"qmp_dp_phy_pll_vco_div_clk" clocks, that are consumed by the display
clock controller. But for boards with multiple enabled QMP USB/DP combo
instances the hard coded names collides - and hence only the first
probed device is allowed to register.

Given that clocks are no longer reference globally by name and it's
possible to replace the hard coded names by something unique, but still
user friendly.

The two new clock names are based on dev_name() and results in names
such as "88ee000.phy::link_clk" and "88ee000.phy::vco_div_clk".

Biju Das b0512a6ec0 phy: renesas: phy-rcar-gen3-usb2: Add USB2.0 PHY support for RZ/G2L
This patch adds USB2.0 PHY support for RZ/G2L SoC.

We need to use a different compatible string due to some differences
with R-Car Gen3 USB2.0 PHY. It uses line ctrl register for OTG_ID
pin changes and different OTG-BC interrupt bit for device recognition.

Tony Lindgren 7481f91f1d phy: phy-twl4030-usb: Disable PHY for suspend
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

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.

JC Kuo c545a90567 phy: tegra: xusb: Add sleepwalk and suspend/resume
This commit adds sleepwalk/wake and suspend/resume interfaces
to Tegra XUSB PHY driver.

Tegra XUSB host controller driver makes use of sleepwalk functions
to enable/disable sleepwalk circuit which is in always-on partition
and can respond to USB resume signals when controller is not powered.
Sleepwalk can be enabled/disabled for any USB UPHY individually.

  - tegra_xusb_padctl_enable_phy_sleepwalk()
  - tegra_xusb_padctl_disable_phy_sleepwalk()

Tegra XUSB host controller driver makes use of wake functions to
enable/disable/query wake circuit which is in always-on partition
can wake system up when USB resume happens.
Wake circuit can be enabled/disabled for any USB PHY individually.

  - tegra_xusb_padctl_enable_phy_wake()
  - tegra_xusb_padctl_disable_phy_wake()
  - tegra_xusb_padctl_remote_wake_detected()

This commit also adds two system suspend stubs that can be used to
save and restore XUSB PADCTL context during system suspend and
resume.
  - tegra_xusb_padctl_suspend_noirq()
  - tegra_xusb_padctl_resume_noirq()

JC Kuo 2352fdb0d3 phy: tegra: xusb: Rearrange UPHY init on Tegra210
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.

The programming sequence in tegra210_usb3_port_enable() is required
for both cold boot and SC7 exit, and must be performed only after
PEX/SATA UPHY is initialized. Therefore, this commit moves the
programming sequence to tegra210_usb3_phy_power_on(). PCIE/SATA phy
.power_on() stub will invoke tegra210_usb3_phy_power_on() if the lane
is assigned for XUSB super-speed.

Manivannan Sadhasivam 952b702bf8 phy: qcom-qmp: Use phy_status field for the status bit offset
In preparation of the support for v4.20 PCIe PHY in SDX55, use a
separate "phy_status" field for the status bit offset. This is needed
because, the v4.20 PHY uses a different offset for the PHY Status.

Rob Herring 8a917813cc phy: Allow a NULL phy name for devm_phy_get()
For a single PHY, there's no reason to have a phy-names entry in DT.
The DT specific get functions allow for this already, but devm_phy_get()
WARNs in this case. Other subsystems also don't warn in their get
functions. Let's drop the WARN for DT case in devm_phy_get().

Linus Torvalds 9d31d23389 Networking changes for 5.13.
Core:
 
  - bpf:
 	- allow bpf programs calling kernel functions (initially to
 	  reuse TCP congestion control implementations)
 	- enable task local storage for tracing programs - remove the
 	  need to store per-task state in hash maps, and allow tracing
 	  programs access to task local storage previously added for
 	  BPF_LSM
 	- add bpf_for_each_map_elem() helper, allowing programs to
 	  walk all map elements in a more robust and easier to verify
 	  fashion
 	- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
 	  redirection
 	- lpm: add support for batched ops in LPM trie
 	- add BTF_KIND_FLOAT support - mostly to allow use of BTF
 	  on s390 which has floats in its headers files
 	- improve BPF syscall documentation and extend the use of kdoc
 	  parsing scripts we already employ for bpf-helpers
 	- libbpf, bpftool: support static linking of BPF ELF files
 	- improve support for encapsulation of L2 packets
 
  - xdp: restructure redirect actions to avoid a runtime lookup,
 	improving performance by 4-8% in microbenchmarks
 
  - xsk: build skb by page (aka generic zerocopy xmit) - improve
 	performance of software AF_XDP path by 33% for devices
 	which don't need headers in the linear skb part (e.g. virtio)
 
  - nexthop: resilient next-hop groups - improve path stability
 	on next-hops group changes (incl. offload for mlxsw)
 
  - ipv6: segment routing: add support for IPv4 decapsulation
 
  - icmp: add support for RFC 8335 extended PROBE messages
 
  - 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
 
  - tcp: reorder tcp_congestion_ops for better cache locality
 
  - mptcp:
 	- add sockopt support for common TCP options
 	- add support for common TCP msg flags
 	- include multiple address ids in RM_ADDR
 	- add reset option support for resetting one subflow
 
  - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
 	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
 
  - veth: allow GRO without XDP - this allows aggregating UDP
 	packets before handing them off to routing, bridge, OvS, etc.
 
  - allow specifing ifindex when device is moved to another namespace

  - add a config knob to turn off per-cpu netdev refcnt to catch
 	underflows in testing
 
 Device APIs:

    -independent APIs
 
  - ethtool:
 	- add interface for reading IEEE MIB stats (incl. mlx5 and
 	  bnxt support)
 	- allow network drivers to dump arbitrary SFP EEPROM data,

 	  which define EEPROM in terms of pages (incl. mlx5 support)
 
  - act_police, flow_offload: add support for packet-per-second
 	policing (incl. offload for nfp)

Yang Yingliang e1723d8b87 phy: phy-twl4030-usb: Fix possible use-after-free in twl4030_usb_remove()
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.

Geert Uytterhoeven 6cb17707aa phy: marvell: ARMADA375_USBCLUSTER_PHY should not default to y, unconditionally
Merely enabling CONFIG_COMPILE_TEST should not enable additional code.
To fix this, restrict the automatic enabling of ARMADA375_USBCLUSTER_PHY
to MACH_ARMADA_375, and ask the user in case of compile-testing.

Sergio Paracuellos 982313c38f phy: ralink: phy-mt7621-pci: fix XTAL bitmask
When this was rewriten to get mainlined and start to
use 'linux/bitfield.h' headers, XTAL_MASK was wrong.
It must mask three bits but only two were used. Hence
properly fix it to make things work.
