Avoid resetting the module-wide i8042_platform_device pointer in
i8042_probe() or i8042_remove(), so that the device can be properly
destroyed by i8042_exit() on module unload.

LoongArch uses ACPI and nearly the same as X86/IA64 for 8042. So modify
i8042-acpipnpio.h slightly and enable it for LoongArch in i8042.h. Then
i8042 driver can work well under the ACPI firmware with PNP typed key-
board and mouse configured in DSDT.

A lot of modern Clevo barebones have touchpad and/or keyboard issues after

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use. No negative effects could be
observed when setting all four.

The list is quite massive as neither the TUXEDO nor the Clevo dmi strings
have been very consistent historically. I tried to keep the list as short
as possible without risking on missing an affected device.

This is revision 3. The Clevo N150CU barebone is still removed as it might
have problems with the fix and needs further investigations. The
SchenkerTechnologiesGmbH System-/Board-Vendor string variations are
added. This is now based in the quirk table refactor. This now also
includes the additional noaux flag for the NS7xMU.

ff946268a0 Input: i8042 - merge quirk tables
Merge i8042 quirk tables to reduce code duplication for devices that need
more than one quirk. Before every quirk had its own table with devices
needing that quirk. If a new quirk needed to be added a new table had to
be created. When a device needed multiple quirks, it appeared in multiple
tables. Now only one table called i8042_dmi_quirk_table exists. In it every
device has one entry and required quirks are coded in the .driver_data
field of the struct dmi_system_id used by this table. Multiple quirks for
one device can be applied by bitwise-or of the new SERIO_QUIRK_* defines.

Also align quirkable options with command line parameters and make vendor
wide quirks per device overwriteable on a per device basis. The first match
is honored while following matches are ignored. So when a vendor wide quirk
is defined in the table, a device can inserted before and therefore
ignoring the vendor wide define.

81b9fd6941 Input: ps2-gpio - don't send rx data before the stop bit
Sending the data before processing the stop bit from the device already
saves the data of the current xfer in case the stop bit is missed.

However, when TX xfers are enabled this introduces a race condition when
a peripheral driver using the bus immediately requests a TX xfer from IRQ
context.

Therefore the data must be send after receiving the stop bit, although
it is possible the data is lost when missing the stop bit.

6283cc9e77 Input: ps2-gpio - remove tx timeout from ps2_gpio_irq_tx()
Actually, there's no extra clock pulse to wait for.

The assumption of an extra clock pulse was mistakenly derived from the
fact that by the time this driver was introduced the GPIO controller of
the test machine (bcm2835) generated spurious interrupts.

Since now spurious interrupts are handled properly this can and must be
removed in order to make TX xfers work properly.

While at it, remove duplicate gpiod_direction_input(). The data gpio
must already be configured to act as input when receiving the ACK bit.

This patch is tested with the original hardware (peripherals and board)
the driver was developed on.

2fa9c57af0 Input: ps2-gpio - use ktime for IRQ timekeeping
Using jiffies for the IRQ timekeeping is not sufficient for two reasons:

(1) Usually jiffies have a resolution of 1ms to 10ms. The IRQ intervals
    based on the clock frequency of PS2 protocol specification (10kHz -
    16.7kHz) are between ~60us and 100us only. Therefore only those IRQ
    intervals can be detected which are either at the end of a transfer
    or are overly delayed. While this is sufficient in most cases, since
    we have quite a lot of ways to detect faulty transfers, it can
    produce false positives in rare cases: When the jiffies value
    changes right between two interrupt that are in time, we wrongly
    assume that we missed one or more clock cycles.

(2) Some gpio controllers (e.g. the one in the bcm283x chips) may generate
    spurious IRQs when processing interrupts in the frequency given by PS2
    devices.

Both issues can be fixed by using ktime resolution for IRQ timekeeping.

However, it is still possible to miss clock cycles without detecting
them. When the PS2 device generates the falling edge of the clock signal
we have between ~30us and 50us to sample the data line, because after
this time we reach the next rising edge at which the device changes the
data signal already. But, the only thing we can detect is whether the
IRQ interval is within the given period. Therefore it is possible to
have an IRQ latency greater than ~30us to 50us, sample the wrong bit on
the data line and still be on time with the next IRQ. However, this can
only happen when within a given transfer the IRQ latency increases
slowly.

9222ba68c3 Input: i8042 - add deferred probe support
We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA.  It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready.  Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module.  However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.

This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above.  When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.

The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry.  As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.

The deferred probe part is based on Fabio's initial work.

87875c1084 parisc: Make struct parisc_driver::remove() return void
The caller of this function (parisc_driver_remove() in
arch/parisc/kernel/drivers.c) ignores the return value, so better don't
return any value at all to not wake wrong expectations in driver authors.

The only function that could return a non-zero value before was
ipmi_parisc_remove() which returns the return value of
ipmi_si_remove_by_dev(). Make this function return void, too, as for all
other callers the value is ignored, too.

Also fold in a small checkpatch fix for:

fc7a6209d5 bus: Make remove callback return void
The driver core ignores the return value of this callback because there
is only little it can do when a device disappears.

This is the final bit of a long lasting cleanup quest where several
buses were converted to also return void from their remove callback.
Additionally some resource leaks were fixed that were caused by drivers
returning an error code in the expectation that the driver won't go
away.

With struct bus_type::remove returning void it's prevented that newly
implemented buses return an ignored error code and so don't anticipate
wrong expectations for driver authors.

7d3370e506 Revert "Input: serio - make write method mandatory"
This reverts commit 81c7c0a350. The idea
to make write method mandatory was flawed as several client drivers
(such as atkbd) check for presence of write() method to adjust behavior
of the driver.

81c7c0a350 Input: serio - make write method mandatory
Given that all serio drivers except one implement write() method
let's make it mandatory to avoid testing for its presence whenever
we attempt to use it.

c932ed0adb TTY / Serial patches for 5.14-rc1
Here is the big set of tty and serial driver patches for 5.14-rc1.
 
 A bit more than normal, but nothing major, lots of cleanups.  Highlights
 are:
 	- lots of tty api cleanups and mxser driver cleanups from Jiri
 	- build warning fixes
 	- various serial driver updates
 	- coding style cleanups
 	- various tty driver minor fixes and updates
 	- removal of broken and disable r3964 line discipline (finally!)
 
 All of these have been in linux-next for a while with no reported
 issues.

f81ee8b8b8 tty: make tty_ldisc_ops a param in tty_unregister_ldisc
Make tty_unregister_ldisc symmetric to tty_register_ldisc by accepting
struct tty_ldisc_ops as a parameter instead of ldisc number. This avoids
checking of the ldisc number bounds in tty_unregister_ldisc.

fbadf70a80 tty: set tty_ldisc_ops::num statically
There is no reason to pass the ldisc number to tty_register_ldisc
separately. Just set it in the already defined tty_ldisc_ops in all the
ldiscs.

This simplifies tty_register_ldisc a bit too (no need to set the num
member there).
