The tc358775 bridge is pin compatible with earlier tc358765 according to
the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the
tc358765, the tc358775 supports a STBY GPIO and higher data rates.
The tc358765 has a register bit for video event mode vs video pulse mode.
We must set it to video event mode for the LCD output to work, and on the
tc358775, this bit no longer exists.
Looks like the registers seem to match otherwise based on a quick glance
comparing the defines to the earlier Android kernel tc358765 driver.

The current code assumes the data-lanes property is configured on the
DSI host side instead of the bridge side, and assumes DSI host endpoint 1.
Let's standardize on what the other bridge drivers are doing and parse the
data-lanes property for the bridge. Only if data-lanes property is not found,
let's be nice and also check the DSI host for old dtb in use and warn.
And as Dmitry pointed out, the lanes for the host and the bridge may be
different because the lanes may be swapped on the host side.

The stby pin is optional. It is only needed for power-up and down

The bridge always uses 24bpp internally. Therefore, for jeida-18
mapping we need to discard the lowest two bits for each channel and thus
starting with LV_[RGB]2. jeida-24 has the same mapping but uses four
lanes instead of three, with the forth pair transmitting the lowest two
bits of each channel. Thus, the mapping between jeida-18 and jeida-24
is actually the same, except that one channel is turned off (by
selecting the RGB666 format in VPCTRL).
While at it, remove the bogus comment about the hardware default because
the default is overwritten in any case.
Tested with a jeida-18 display (Evervision VGG644804).

The tc358765 is similar to tc358775. The tc358765 just an earlier version
of the hardware, and it's pin and register compatible with tc358775 for
most part.
From the binding point of view the only difference is that the tc358765
does not have stdby-gpios.

The device uses a clock lane, and 1 to 4 DSI data lanes. Let's add the
data-lanes property starting at 1 similar to what the other bridge
bindings are doing.
Let's also drop the data-lanes properties in the example for the DSI host
controller to avoid confusion. The configuration of the DSI host depends
on the controller used and is unrelated to the bridge binding.

Stop relying on the dev_priv local variable in the DSI register
macros. Pass struct intel_display pointer to the macros. Move the MIPI
DSI MMIO base selection to a different level, passing it to _MMIO_MIPI()
and doing the addition there.
Start using the local display variable for all intel_de_* usage, and
opportunistically use it for other things than display registers as
well.

When KUnit tests are enabled, under very big kernel configurations
(e.g. `allyesconfig`), we can trigger a `rustdoc` ICE [1]:
RUSTDOC TK rust/kernel/lib.rs
error: the compiler unexpectedly panicked. this is a bug.
The reason is that this build step has a duplicated `@rustc_cfg` argument,
which contains the kernel configuration, and thus a lot of arguments. The
factor 2 happens to be enough to reach the ICE.
Thus remove the unneeded `@rustc_cfg`. By doing so, we clean up the
command and workaround the ICE.
The ICE has been fixed in the upcoming Rust 1.79 [2].

The thread that calls the module initialisation code when a module is
loaded is not guaranteed [in fact, it is unlikely] to be the same one
that calls the module cleanup code on module unload, therefore, `Module`
implementations must be `Send` to account for them moving from one
thread to another implicitly.

During module probe, regulator 'vin' and 'vdd-io' are used and enabled,
but the vdd-io regulator overwrites the 'vin' regulator pointer. During
remove, only the vdd-io is disabled, as the vin regulator pointer is not
available anymore. When regulator_put() is called during resource
cleanup a kernel warning is given, as the regulator is still enabled.
Store the two regulators in separate pointers and disable both the
regulators on module remove.

mv88e6250_phylink_get_caps()
With the recent PHYLINK changes requiring supported_interfaces to be set,
MV88E6250 family switches like the 88E6020 fail to probe - cmode is
never initialized on these devices, so mv88e6250_phylink_get_caps() does
not set any supported_interfaces flags.
Instead of a cmode, on 88E6250 we have a read-only port mode value that
encodes similar information. There is no reason to bother mapping port
mode to the cmodes of other switch models; instead we introduce a
mv88e6250_setup_supported_interfaces() that is called directly from
mv88e6250_phylink_get_caps().
