The RENESAS FemtoClock3 Wireless is a high-performance jitter attenuator,
frequency translator, and clock synthesizer. The device is comprised of 3
digital PLLs (DPLL) to track CLKIN inputs and three independent low phase
noise fractional output dividers (FOD) that output low phase noise clocks.
FemtoClock3 supports one Time Synchronization (Time Sync) channel to enable
an external processor to control the phase and frequency of the Time Sync
channel and to take phase measurements using the TDC. Intended applications
are synchronization using the precision time protocol (PTP) and
synchronization with 0.5 Hz and 1 Hz signals from GNSS.

This change is for the PHC devices that can measure the phase offset
between PHC signal and the external signal, such as the 1PPS signal of
GNSS. Reporting PTP_CLOCK_EXTOFF to user space will be piggy-backed to
the existing ptp_extts_event so that application such as ts2phc can
poll the external offset the same way as extts. Hence, ts2phc can use
the offset to achieve the alignment between PHC and the external signal
by the help of either SW or HW filters.

If a GPIO driver returns a positive integer from one of the direction
setter callbacks, we'll end up propagating it to user-space. Whether we
should sanitize the values returned by callbacks is a different question
but let's first improve the documentation and fortify the contract with
GPIO providers.

If CONFIG_SERIAL_8250_HP300=y and CONFIG_SERIAL_8250_CONSOLE=y (e.g.

Fix this by moving the existing prototype in arch/m68k/hp300/config.c to

receive_buf() is called from ttyport_receive_buf() that expects values
">= 0" from serdev_controller_receive_buf(), change its return type from
ssize_t to size_t.
The need for this clean-up was noticed while fixing a warning, see
commit 94d053942544 ("Bluetooth: btnxpuart: fix recv_buf() return value").
Changing the callback prototype to return an unsigned seems the best way
to document the API and ensure that is properly used.
GNSS drivers implementation of serdev receive_buf() callback return
directly the return value of gnss_insert_raw(). gnss_insert_raw()
returns a signed int, however this is not an issue since the value
returned is always positive, because of the kfifo_in() implementation.
gnss_insert_raw() could be changed to return also an unsigned, however
this is not implemented here as request by the GNSS maintainer Johan
Hovold.

selection.c and vt.c still uses tabs in the kernel-doc. This misrenders the
functions in the output -- sphinx misinterprets the description. So
remove these tabs, incl. those around dashes.
'enum' keyword is needed before enum names. Fix that.
Superfluous \n after the comments are also removed. They are not
completely faulty, but this unifies all the kernel-doc in the files.
Finally fix up the cross references.

There are currently two places with VESA blanking constants definitions:
fb.h and console.h. Extract/unify the two to a separate header (vesa.h).
Given the fb's is in an uapi header, create the common header in uapi
too.
Note that instead of macros, an enum (vesa_blank_mode) is created. But
the macros are kept too (they now expand to the enum constants), just in
case someone in userspace performs some #ifdeffery.

In consw::con_clear():
* Height is always 1, so drop it.
* Offsets and width are always unsigned values, so re-type them as such.
This needs a new __fbcon_clear() in the fbcon code to still handle
height which might not be 1 when called internally.

It is pretty unfortunate to set vc_data::vc_resize_user in two callers
of vc_do_resize(). vc_resize_user is immediately reset there (while
remembering it). So instead of this back and forth, pass 'from_user' as
a parameter.
Notes on 'int user':
* The name changes from 'user' to 'from_user' on some places to be
consistent.
* The type is bool now as 'int user' might evoke user's uid or whatever.
Provided vc_resize() is called on many places and they need not to care
about this parameter, its prototype is kept unchanged. Instead, it is
now an inline calling a new __vc_resize() which implements the above.
This patch makes the situation much more obvious.

Pass proper types and proper pointers (the data with an offset) to the
TIOCL_* handlers. So that they need not to cast or add anything to the
passed pointer.
This makes obvious what is passed/consumed.

Since commit 74d58cd48a8f ("USB: sisusbvga: remove console support"),
vgacon_scrolldelta() is the only user of vc_scrolldelta_helper().
Inline the helper into vgacon_scrolldelta() and drop it.

Add data message handling and Discover Identity SVDM over SOP'
This patch contains the following changes:
1. pd_vdo
Add VDO indices for active and passive cables, documentation to reflect
expected number of objects depending on PD Revision, and macro to indicate
port parter is data host capable.
2. tcpm
Add typec_cable and typec_plug to tcpm_port to maintain cable and plug
information. tcpm_port also adds send_discover_prime to indicate that
Discover Identity should be sent out of the ready state.
tcpm_queue_vdm and tcpm_send_vdm now take the SOP* type when transmitting
messages. tcpm_handle_vdm_request and tcpm_pd_svdm also use the SOP* type.
tcpm_pd_svdm handles Discover Identity messages for SOP and SOP'. In the
SOP case, the port uses tcpm_attempt_vconn_swap_discovery to determine if
a Vconn swap is needed for cable communication. Otherwise, the port will
send Discover Identity on SOP' if it can, or default to Discover SVIDs.
svdm_consume_identity_sop_prime consumes the result of Discover Identity
on SOP'. It fills out cable identity and description, and it registers
the cable. The SOP' plug is registered as well.
The VDM state machine is adjusted to construct messages based on the SOP*
type. If a transmission error occurs after the max number of retries for
Discover Identity over SOP', then the port will send Discover SVIDs over
SOP.

Add attempt_vconn_swap_discovery callback to determine whether the TCPM
should perform a Vconn swap following Discover Identity on SOP. The tcpci
will return false unless chip level drivers implement the callback.
Maxim based TCPCs will return true unless the last connection resulted in
a Vconn Over Current Fault, which may be the result of the Vconn swap. In
addition to the port resetting, the TCPCI will veto the next Vconn swap
from occurring.

Add tx_sop_type to tcpm_pd_send_control and rx_sop_type to
tcpm_pd_ctrl_request. TCPC_TX_SOP is added to all pd_send_control calls,
but TCPC_TX_SOP_PRIME is added to pd_send_control for a SOFT_RESET message
sent after a Vconn swap that makes the Port the Vconn source. Likewise,
tcpm_pd_ctrl_request resets the proper protocol layer depending on
rx_sop_type for SOFT_RESET.
VCONN_SWAP_TURN_ON_VCONN now moves to a new state,
VCONN_SWAP_SEND_SOFT_RESET. This state sends SOFT_RESET over SOP' before
transitioning to the ready state if applicable. It transitions after
PD_T_VCONN_STABLE, definied in pd.h as the time required for Vconn to be
on before transmitting messages.

tcpm_pd_receive adds the SOP type as a parameter, and passes it within the
pd_rx_event struct for tcpm_pd_rx_handler to use. For now, the handler
drops all SOP' messages.
Maxim based tcpci drivers are capable of SOP' communication, so process_rx
now takes the SOP type into account and passes the value to
tcpm_pd_receive.
tcpci_set_pd_rx now utilizes the cable_comm_capable flag to determine if
TCPC_RX_DETECT_SOP1 should be added to the bitfield when enabling PD
message reception.
For all other consumers of tcpm_pd_receive, default the new field to
TCPC_TX_SOP.

Add cable_comm_capable to tcpci_data for tcpci drivers to indicate that
the port tcpc is capable of communicating to cables over SOP. A
corresponding tcpci callback tcpci_cable_comm_capable returns this value.
The tcpm will primarily use this in later patches to determine if the port
can transmit and receive SOP' messages.
Maxim based tcpci drivers are capable of SOP' communication, so the
cable_comm_capable flag is set to true.

Add typec_cable_set_svdm_version and typec_get_cable_svdm version symbols.
Cables can operate under a lower PD revision than the port partner, and the
max SVDM version is tied to the PD revision. So, typec_cable maintains its
own svdm_version.
Add typec_altmode_get_cable_svdm_version to return the cable's negotiated
svdm_version for altmode drivers to use.

Add typec_cable_ops struct for enter, exit, and vdm. The struct is added
to typec_altmode so port alt modes can have access to partner and cable
specific callbacks, and alt mode drivers can specify operations over SOP'

typec_port_register_cable_ops is added as a new symbol for port drivers
to use to register cable operations to their registered port alt modes.

====================
pull-request: bpf-next 2024-01-26
We've added 107 non-merge commits during the last 4 day(s) which contain
a total of 101 files changed, 6009 insertions(+), 1260 deletions(-).
The main changes are:
1) Add BPF token support to delegate a subset of BPF subsystem
functionality from privileged system-wide daemons such as systemd
through special mount options for userns-bound BPF fs to a trusted
& unprivileged application. With addressed changes from Christian
and Linus' reviews, from Andrii Nakryiko.
2) Support registration of struct_ops types from modules which helps
projects like fuse-bpf that seeks to implement a new struct_ops type,
from Kui-Feng Lee.
3) Add support for retrieval of cookies for perf/kprobe multi links,
from Jiri Olsa.
4) Bigger batch of prep-work for the BPF verifier to eventually support
preserving boundaries and tracking scalars on narrowing fills,
from Maxim Mikityanskiy.
5) Extend the tc BPF flavor to support arbitrary TCP SYN cookies to help
with the scenario of SYN floods, from Kuniyuki Iwashima.
6) Add code generation to inline the bpf_kptr_xchg() helper which
improves performance when stashing/popping the allocated BPF objects,
from Hou Tao.
7) Extend BPF verifier to track aligned ST stores as imprecise spilled
registers, from Yonghong Song.
8) Several fixes to BPF selftests around inline asm constraints and
unsupported VLA code generation, from Jose E. Marchesi.
9) Various updates to the BPF IETF instruction set draft document such
as the introduction of conformance groups for instructions,
from Dave Thaler.
10) Fix BPF verifier to make infinite loop detection in is_state_visited()
exact to catch some too lax spill/fill corner cases,
from Eduard Zingerman.
11) Refactor the BPF verifier pointer ALU check to allow ALU explicitly
instead of implicitly for various register types, from Hao Sun.
12) Fix the flaky tc_redirect_dtime BPF selftest due to slowness
in neighbor advertisement at setup time, from Martin KaFai Lau.
13) Change BPF selftests to skip callback tests for the case when the
JIT is disabled, from Tiezhu Yang.
14) Add a small extension to libbpf which allows to auto create
a map-in-map's inner map, from Andrey Grafin.
