Make sure modes with crazy big dotclocks are rejected early,
so as to not cause problems for subsequent code via integer
overflows and whatnot.
These would eventually be rejected in intel_crtc_compute_pipe_mode()
but that is now too late as we do the clock computations a bit
earlier than that. And we don't want to just reorder the two since
we still want to check the final computed dotclock against the
hardware limit to make sure we didn't end up above the limit due
to rounding/etc.

Current PSR code is supposed to use TRANSCODER_EDP to force 0 shift for
bits in PSR_IMR/IIR registers:
/*
* gen12+ has registers relative to transcoder and one per transcoder
* using the same bit definition: handle it as TRANSCODER_EDP to force
* 0 shift in bit definition
*/
At the time of writing the code assumption "TRANSCODER_EDP == 0" was made.
This is not the case and all fields in PSR_IMR and PSR_IIR are shifted
incorrectly if DISPLAY_VER >= 12.
Fix this by adding separate register field defines for >=12 and add bit
getter functions to keep code readability.
v4:
- Remove EDP from TGL definitions (José)
- Use REG_BIT and REG_GENMASK (José)
v3:
- Add separate register field defines (José)
- Add bit getter functions (José)
v2:
- Improve commit message (José)

The irqchip->irq_set_type method is called by __irq_set_trigger() under
the desc->lock raw spinlock.
The ls-extirq implementation, ls_extirq_irq_set_type(), uses an MMIO
regmap created by of_syscon_register(), which uses plain spinlocks
(the kind that are sleepable on RT).
Therefore, this is an invalid locking scheme for which we get a kernel
splat stating just that ("[ BUG: Invalid wait context ]"), because the
context in which the plain spinlock may sleep is atomic due to the raw
spinlock. We need to go raw spinlocks all the way.
Make this driver ioremap its INTPCR register on its own, and stop
relying on syscon to provide a regmap.

ASoC: Updates for v6.1
This has been a very quiet release for the core but quite a busy one for
drivers with a big crop of new drivers and lots of feature additions and
fixes to existing ones:
- A new string helper parse_int_array_user().
- Improvements to the SOF IPC4 code, especially around trace.
- Support for AMD Rembrant DSPs, AMD Pink Sardine ACP 6.2, Apple Silcon
systems, Everest ES8326, Intel Sky Lake and Kaby Lake, MediaTek
MT8186 support, NXP i.MX8ULP DSPs, Qualcomm SC8280XP, SM8250 and SM8450
and Texas Instruments SRC4392
There is a conflict with the conversion of I2C remove functions to void
in the cs42l42 driver which is fairly straightforward to resolve but
should be highlighted to Linus.

LoongArch architecture changes for 6.1 depend on the efi changes to

wwan_register_ops calls wwan_create_default_link, which ends up in the
ipc_wwan_newlink callback that locks ipc_wwan->if_mutex. However, this
mutex is not yet initialized by that point. Fix it by moving mutex_init
above the wwan_register_ops call. This also makes the order of
operations in ipc_wwan_init symmetric to ipc_wwan_deinit.

This patch introduces the macsec offload feature to cn10k
PF netdev driver. The macsec offload ops like adding, deleting
and updating SecYs, SCs, SAs and stats are supported. XPN support
will be added in later patches. Some stats use same counter in hardware
which means based on the SecY mode the same counter represents different
stat. Hence when SecY mode/policy is changed then snapshot of current
stats are captured. Also there is no provision to specify the unique
flow-id/SCI per packet to hardware hence different mac address needs to
be set for macsec interfaces.

Hardware triggers an interrupt for events like PN wrap to zero,
PN crosses set threshold. This interrupt is received
by the MCS_AF. MCS AF then finds the PF/VF to which SA is mapped
and notifies them using mcs_intr_notify mbox message.
PF/VF using mcs_intr_cfg mbox can configure the list
of interrupts for which they want to receive the
notification from AF.

CN10K-B and CNF10K-B has macsec block(MCS) to encrypt and
decrypt packets at MAC level. This block is a global resource
with hardware resources like SecYs, SCs and SAs and is in
between NIX block and RPM LMAC. CN10K-B silicon has only one MCS
block which receives packets from all LMACS whereas CNF10K-B has
seven MCS blocks for seven LMACs. Both MCS blocks are
similar in operation except for few register offsets and some
configurations require writing to different registers. Those
differences between IPs are handled using separate ops.
This patch adds basic driver and does the initial hardware
calibration and parser configuration.

This patch optimizes the RX buffer management by using the page
pool. The purpose for this change is to prepare for the following
XDP support. The current driver uses one frame per page for easy
management.
Added __maybe_unused attribute to the following functions to avoid
the compiling warning. Those functions will be removed by a separate
patch once this page pool solution is accepted.
- fec_enet_new_rxbdp
- fec_enet_copybreak
The following are the comparing result between page pool implementation
and the original implementation (non page pool).
--- small packet (64 bytes) testing are almost the same
--- no matter what the implementation is
--- on both i.MX8 and i.MX6SX platforms.

bnx2x_tpa_stop() allocates a memory chunk from new_data with
bnx2x_frag_alloc(). The new_data should be freed when gets some error.
But when "pad + len > fp->rx_buf_size" is true, bnx2x_tpa_stop() returns
without releasing the new_data, which will lead to a memory leak.
We should free the new_data with bnx2x_frag_free() when "pad + len >
fp->rx_buf_size" is true.

This adds support for multigig copper SFP modules from RollBall/Hilink.

Some multigig SFPs from RollBall and Hilink do not expose functional
MDIO access to the internal PHY of the SFP via I2C address 0x56
(although there seems to be read-only clause 22 access on this address).
Instead these SFPs PHY can be accessed via I2C via the SFP Enhanced
Digital Diagnostic Interface - I2C address 0x51. The SFP_PAGE has to be
selected to 3 and the password must be filled with 0xff bytes for this
PHY communication to work.
This extends the mdio-i2c driver to support this protocol by adding a
special parameter to mdio_i2c_alloc function via which this RollBall
protocol can be selected.

Instead of configuring the I2C mdiobus when SFP driver is probed,
create/destroy the mdiobus before the PHY is probed for/after it is
released.
This way we can tell the mdio-i2c code which protocol to use for each
SFP transceiver.
Move the code that determines MDIO I2C protocol from
sfp_sm_probe_for_phy() to sfp_sm_mod_probe(), where most of the SFP ID
parsing is done. Don't allocate I2C bus if no PHY is expected.

Select the host interface configuration according to the capabilities of
the host if the host provided them. This is currently provided only when
connecting PHY that is inside a SFP.
The PHY supports several configurations of host communication:
- always communicate with host in 10gbase-r, even if copper speed is
lower (rate matching mode),
- the same as above but use xaui/rxaui instead of 10gbase-r,
- switch host SerDes mode between 10gbase-r, 5gbase-r, 2500base-x and
sgmii according to copper speed,
- the same as above but use xaui/rxaui instead of 10gbase-r.
This mode of host communication, called MACTYPE, is by default selected
by strapping pins, but it can be changed in software.
This adds support for selecting this mode according to which modes are
supported by the host.
This allows the kernel to:
- support SFP modules with 88X33X0 or 88E21X0 inside them
Note: we use mv3310_select_mactype() for both 88X3310 and 88X3340,
although 88X3340 does not support XAUI. This is not a problem because
88X3340 does not declare XAUI in it's supported_interfaces, and so this
function will never choose that MACTYPE.

Pass the supported PHY interface types to phylib if the PHY we are
connecting is inside a SFP, so that the PHY driver can select an
appropriate host configuration mode for their interface according to
the host capabilities.
For example the Marvell 88X3310 PHY inside RollBall SFP modules
defaults to 10gbase-r mode on host's side, and the marvell10g
driver currently does not change this setting. But a host may not
support 10gbase-r. For example Turris Omnia only supports sgmii,
1000base-x and 2500base-x modes. The PHY can be configured to use
those modes, but in order for the PHY driver to do that, it needs
to know which modes are supported.

We currently parse the SFP EEPROM to a bitmap of ethtool link modes,
and then attempt to convert the link modes to a PHY interface mode.
While this works at present, there are cases where this is sub-optimal.
For example, where a module can operate with several different PHY
interface modes.
To start addressing this, arrange for the SFP EEPROM parsing to also
provide a bitmap of the possible PHY interface modes.

On pre-ddi platforms we have slightly different code being
used for HDMI TMDS clock to dotclock conversion between the
state computation and state readout. Both of these need to
round the same way in order to not get a mismatch between
the computed and read out states. Fix up the rounding
direction in the readout path to match what is used during
state computation.
Another option would to just use intel_crtc_dotclock()
in the readout path as well, but I don't really want to
do that as the current code more accurately represents
how the hardware really works; The HDMI port register
defines whether we're actually outputting 8bpc or 12bpc
over HDMI, and the PIPECONF bpc setting just defines what
goes over FDI between the CPU and PCH. The fact that we
try to cram all that into a single pipe_bpp during state
computation is perhaps not entirely great...

Generally, device drivers should just rely on the platform data like
devicetree to supply the clocks required for the functioning of the
peripheral. There is no need to hardcode the clk info in the driver.
So get rid of the static clk info and obtain the platform supplied
clks.
The total number of clocks supplied is obtained using the
devm_clk_bulk_get_all() API and used for the rest of the clk_bulk_ APIs.
