Returning an error when a read/write is not implemented makes no
sense, especially on read where no return value makes sense.
Change the logic to directly fallback to mmio. If a platform truly
wants other read/writes that are not plain vanilla mmio, it needs to
implement its own routines.

Some delay occurs between each bursts, thus the default delay is wrong

Not all Dekel PHY registers have a lane instance, so having to specify
this when using them is awkward. It makes more sense to define each PHY
register with its full internal PHY offset where bits 15:12 is the lane
for lane-instanced PHY registers and just a register bank index for other
PHY registers. This way lane-instanced registers can be referred to with
the (tc_port, lane) parameters, while other registers just with a tc_port
parameter.
An additional benefit of this change is to prevent passing a Dekel
register to a generic MMIO access function or vice versa.

Accessing the TypeC DKL PHY registers during modeset-commit,
-verification, DP link-retraining and AUX power well toggling is racy
due to these code paths being concurrent and the PHY register bank
selection register (HIP_INDEX_REG) being shared between PHY instances

PHY register access.
Add the required locking around each PHY register bank selection->

The channel-subsystem-driver scans for newly available devices whenever
device-IDs are removed from the cio_ignore list using a command such as:
echo free >/proc/cio_ignore
Since an I/O device scan might interfer with running I/Os, commit
172da89ed0 ("s390/cio: avoid excessive path-verification requests")
introduced an optimization to exclude online devices from the scan.
The newly added check for online devices incorrectly assumes that
an I/O-subchannel's drvdata points to a struct io_subchannel_private.
For devices that are bound to a non-default I/O subchannel driver, such
as the vfio_ccw driver, this results in an out-of-bounds read access
during each scan.
Fix this by changing the scan logic to rely on a driver-independent
online indication. For this we can use struct subchannel->config.ena,
which is the driver's requested subchannel-enabled state. Since I/Os
can only be started on enabled subchannels, this matches the intent
of the original optimization of not scanning devices where I/O might
be running.

Using z/VM the 3270 terminal emulator also emulates an IBM 3215 console
which outputs line by line. When the screen is full, the console enters
the MORE... state and waits for the operator to confirm the data
on the screen by pressing a clear key. If this does not happen in the
default time frame (currently 50 seconds) the console enters the HOLDING
state.
It then waits another time frame (currently 10 seconds) before the output
continues on the next screen. When the operator presses the clear key
during these wait times, the output continues immediately.
This may lead to a very long boot time when the console
has to print many messages, also the system may hang because of the
console's limited buffer space and the system waits for the console
output to drain and finally to finish. This problem can only occur
when a terminal emulator is actually connected to the 3215 console
driver. If not z/VM simply drops console output.
Remedy this rare situation and add a kernel boot command line parameter
con3215_drop. It can be set to 0 (do not drop) or 1 (do drop) which is
the default. This instructs the kernel drop console data when the
console buffer is full. This speeds up the boot time considerable and
also does not hang the system anymore.
Add a sysfs attribute file for console IBM 3215 named con_drop.
This allows for changing the behavior after the boot, for example when
during interactive debugging a panic/crash is expected.
Here is a test of the new behavior using the following test program:
#/bin/bash
declare -i cnt=4
mode=$(cat /sys/bus/ccw/drivers/3215/con_drop)
[ $mode = yes ] && cnt=25
echo "cons_drop $(cat /sys/bus/ccw/drivers/3215/con_drop)"
echo "vmcp term more 5 2"
vmcp term more 5 2

echo "$i. command 'echo t > /proc/sysrq-trigger' at $(date +%F,%T)"

sleep 1
done
echo "droptest done" > /dev/kmsg
#
Output with sysfs attribute con_drop set to 1:
# ./droptest.sh

Details:
Enable function raw3215_write() to handle tab expansion and newlines
and feed it with input not larger than the console buffer of 65536
bytes. Function raw3125_putchar() just forwards its character for
output to raw3215_write().
This moves tab to blank conversion to one function raw3215_write()
which also does call raw3215_make_room() to wait for enough free
buffer space.
Function handle_write() loops over all its input and segments input
into chunks of console buffer size (should the input be larger).
Rework tab expansion handling logic to avoid code duplication.

Define a common COMMUNITY macro and supply a variant to it.
This removes some verbosity in macros.

Some x86/ACPI laptops with MIPI cameras have a LATT2021 ACPI device
in the _DEP dependency list of the ACPI devices for the camera-sensors
(which have flags.honor_deps set).
The _DDN for the LATT2021 device is "Lattice FW Update Client Driver",
suggesting that this is used for firmware updates of something. There
is no Linux driver for this and if Linux gets support for updates it
will likely be in userspace through fwupd.
For now add the LATT2021 HID to acpi_ignore_dep_ids[] so that
acpi_dev_ready_for_enumeration() will return true once the other _DEP
dependencies are met.

Like the Asus Vivobook K3402ZA/K3502ZA/S5402ZA Asus Vivobook S5602ZA
has an ACPI DSDT table the describes IRQ 1 as ActiveLow while the kernel
overrides it to Edge_High. This prevents the keyboard on this laptop
from working. To fix this add this laptop to the skip_override_table so
that the kernel does not override IRQ 1.

Platforms can provide the information about the availability of each
idle states via status flag. Platforms may have to disable one or more
idle states for various reasons like broken firmware or other unmet
dependencies.
Fix handling of such unavailable/disabled idle states by ignoring them
while parsing the states.

Add the module clock used by the SPI Multi I/O Bus Controller (RPC-IF)
on the Renesas R-Car V4H (R8A779G0) SoC.
While at it, fix table alignment in the definition of the related
RPCSRC internal clock.
