The Pavilion 13 x360 PC has a chassis-type which does not indicate it is
a convertible, while it is actually a convertible. Add it to the
dmi_switches_allow_list.

The commit 78429e55e4057 ("platform/x86: toshiba_acpi: Clean up
variable declaration") cleans up variable declaration in
video_proc_write(). Seems it does the variable assignment in the
wrong place, this results in dead code and changes the source code
logic. Fix it by doing the assignment at the beginning of the funciton.

The lid state may change while the machine is suspended. As such, we may
need to re-check the state at wake-up time (at least when waking up from
hibernation).
Add the appropriate call to the resume handler in order to sync the
SW_TABLET_MODE switch state with the hardware state.

Yoga 11e 4th gen
The Thinkpad Yoga 11e 4th gen with the N3450 / Celeron CPU only has
one battery which is named BAT1 instead of the expected BAT0, add a
quirk for this. This fixes not being able to set the charging tresholds
on this model; and this alsoe fixes the following errors in dmesg:
ACPI: \_SB_.PCI0.LPCB.EC__.HKEY: BCTG evaluated but flagged as error
thinkpad_acpi: Error probing battery 2
battery: extension failed to load: ThinkPad Battery Extension
battery: extension unregistered: ThinkPad Battery Extension
Note that the added quirk is for the "R0K" BIOS versions which are
used on the Thinkpad Yoga 11e 4th gen's with a Celeron CPU, there
is a separate "R0L" BIOS for the i3/i5 based versions. This may also
need the same quirk, but if that really is necessary is unknown.

The Yoga 11e series has 2 accelerometers described by a BOSC0200 ACPI node.
This setup relies on a Windows service which reads both accelerometers and
then calculates the angle between the 2 halves to determine laptop / tent /
tablet mode and then reports the calculated mode back to the EC by calling
special ACPI methods on the BOSC0200 node.
The bmc150 iio driver does not support this (it involves double
calculations requiring sqrt and arccos so this really needs to be done
in userspace), as a result of this on the Yoga 11e the thinkpad_acpi
code always reports SW_TABLET_MODE=0, starting with GNOME 3.38 reporting
SW_TABLET_MODE=0 causes GNOME to:
1. Not show the onscreen keyboard when a text-input field is focussed
with the touchscreen.
2. Disable accelerometer based auto display-rotation.
This makes sense when in laptop-mode but not when in tablet-mode. But
since for the Yoga 11e the thinkpad_acpi code always reports
SW_TABLET_MODE=0, GNOME does not know when the device is in tablet-mode.
Stop reporting the broken (always 0) SW_TABLET_MODE on Yoga 11e models
to fix this.
Note there are plans for userspace to support 360 degree hinges style
2-in-1s with 2 accelerometers and figure out the mode by itself, see:

This patch is to support Armv8.3 extension for SPE, it adds alignment
field in the Events packet and it supports the Scalable Vector Extension
(SVE) for Operation packet and Events packet with two additions:
- The vector length for SVE operations in the Operation Type packet;
- The incomplete predicate and empty predicate fields in the Events
packet.

For the operation type packet payload with load/store class, it misses
to support these sub classes:
- A load/store targeting the general-purpose registers;
- A load/store targeting unspecified registers;
- The ARMv8.4 nested virtualisation extension can redirect system
register accesses to a memory page controlled by the hypervisor.
The SPE profiling feature in newer implementations can tag those
memory accesses accordingly.
Add the bit pattern describing load/store sub classes, so that the perf
tool can decode it properly.
Inspired by Andre Przywara, refined the commit log and code for more
clear description.

In the Armv8 ARM (ARM DDI 0487F.c), chapter "D10.2.6 Events packet", it
describes the event bit is valid with specific payload requirement. For
example, the Last Level cache access event, the bit is defined as:
E[8], byte 1 bit [0], when SZ == 0b01 , when SZ == 0b10 ,
or when SZ == 0b11
It requires the payload size is at least 2 bytes, when byte 1 (start
counting from 0) is valid, E[8] (bit 0 in byte 1) can be used for LLC
access event type. For safety, the code checks the condition for
payload size firstly, if meet the requirement for payload size, then
continue to parse event type.
If review function arm_spe_get_payload(), it has used cast, so any bytes
beyond the valid size have been set to zeros.
For this reason, we don't need to check payload size anymore afterwards
when parse events, thus this patch removes payload size conditions.

To establish a valid address from the address packet payload and finally
the address value can be used for parsing data symbol in DSO, current
code uses 0xff to replace the tag in the top byte of data virtual
address.
So far the code only fixups top byte for the memory layouts with 4KB
pages, it misses to support memory layouts with 64KB pages.
This patch adds the conditions for checking bits [55:52] are 0xf, if
detects the pattern it will fill 0xff into the top byte of the address,
also adds comment to explain the fixing up.

The packet header parsing uses the hard coded values and it uses nested
if-else statements.
To improve the readability, this patch refactors the macros for packet
header format so it removes the hard coded values. Furthermore, based
on the new mask macros it reduces the nested if-else statements and
changes to use the flat conditions checking, this is directive and can
easily map to the descriptions in ARMv8-a architecture reference manual
(ARM DDI 0487E.a), chapter 'D10.1.5 Statistical Profiling Extension
protocol packet headers'.

When outputs strings to the decoding buffer with function snprintf(),
SPE decoder needs to detects if any error returns from snprintf() and if
so needs to directly bail out. If snprintf() returns success, it needs
to update buffer pointer and reduce the buffer length so can continue to
output the next string into the consequent memory space.
This complex logics are spreading in the function arm_spe_pkt_desc() so
there has many duplicate codes for handling error detecting, increment
buffer pointer and decrement buffer size.
To avoid the duplicate code, this patch introduces a new helper function
arm_spe_pkt_out_string() which is used to wrap up the complex logics,
and it's used by the caller arm_spe_pkt_desc(). This patch moves the
variable 'blen' as the function's local variable so allows to remove
the unnecessary braces and improve the readability.
This patch simplifies the return value for arm_spe_pkt_desc(): '0' means
success and other values mean an error has occurred. To realize this,
it relies on arm_spe_pkt_out_string()'s parameter 'err', the 'err' is a
cumulative value, returns its final value if printing buffer is called
for one time or multiple times. Finally, the error is handled in a
central place, rather than directly bailing out in switch-cases, it
returns error at the end of arm_spe_pkt_desc().
This patch changes the caller arm_spe_dump() to respect the updated
return value semantics of arm_spe_pkt_desc().

This patch add a check to the mcp251xfd_probe() function to bail out and give
the user a proper error message if no IRQ is specified. Otherwise the driver
will probe just fine but ifup will fail with a meaningless "RTNETLINK answers:
Invalid argument" error message.

The firmware on the original USB2CAN by Geschwister Schneider Technologie
Entwicklungs- und Vertriebs UG exchanges all data between the host and the
device in host byte order. This is done with the struct
gs_host_config::byte_order member, which is sent first to indicate the desired
byte order.
The widely used open source firmware candleLight doesn't support this feature
and exchanges the data in little endian byte order. This breaks if a device
with candleLight firmware is used on big endianess systems.
To fix this problem, all u32 (but not the struct gs_host_frame::echo_id, which
is a transparent cookie) are converted to __le32.

As defined at ETSI TS 101 162, original network IDs up to 0xfebf
are reserved for registration at dvb.org.
Let's use, instead, an original network ID at the range
0xff00-0xffff, as this is for private temporary usage.
As the same value is also used for the network ID,
the range 0xff01-0xffff also fits better, as values
lower than that depend if the network is used for
satellite, terrestrial, cable of CI.
While here, move the TS ID to the bridge code, where it
is used, and change its value, as it was identical to
the value previously used by network ID. While we could
keep the same value, let's change it, just to make easier
to check for the new code while reading it with DVB tools
like dvbinspector.
