Dell All In One (AIO) models released after 2017 use a backlight controller
board connected to an UART.
In DSDT this uart port will be defined as:
Name (_HID, "DELL0501")
Name (_CID, EisaId ("PNP0501")
Instead of having a separate ACPI device with an UartSerialBusV2() resource
to model the backlight-controller, which would be the standard way to do
this.
The acpi_quirk_skip_serdev_enumeration() has special handling for this
and it will make the serial port code create a serdev controller device
for the UART instead of a /dev/ttyS0 char-dev. It will also create
a dell-uart-backlight driver platform device for this driver to bind too.
This new kernel module contains 2 drivers for this:
1. A simple platform driver which creates the actual serdev device
(with the serdev controller device as parent)
2. A serdev driver for the created serdev device which exports
the backlight functionality uses a standard backlight class device.

The Xiaomi [Mi]Pad 2 has 3 menu / home / back capacitive touch-buttons
on its bottom bezel. These are backlit by LEDs attached to a TPS61158 LED
controller which is controlled by the "pwm_soc_lpss_2" PWM output.
Create a LED class device for this, using the new input-events trigger
as default trigger so that the buttons automatically light up on any
input activity.
Note alternatively a "leds_pwm" platform device could be created together
with the necessary fwnode_s_ and a fwnode link to the PWM controller.
There are 2 downsides to this approach:
1. The code would still need to pwm_get() the PWM controller to get/attach
a fwnode for the PWM controller fwnode link and setting up the necessary
fwnodes is non-trivial. So this would likely require more code then simply
registering the LED class device directly.
2. Currently the leds_pwm driver and its devicetree bindings do not support
limiting the maximum dutycycle to less then 100% which is required in this
case (the leds_pwm driver can probably be extended to allow this).

The P2SB could get an invalid BAR from the BIOS, and that won't be fixed
up until pcibios_assign_resources(), which is an fs_initcall().
- Move p2sb_fs_init() to an fs_initcall_sync(). This is still early
enough to avoid a race with any dependent drivers.
- Add a check for IORESOURCE_UNSET in p2sb_valid_resource() to catch
unset BARs going forward.

A partitioned system has two different PCI VSEC devices per package.
A non-partitioned device has only one PCI VSEC device per package.
The current implementation only supports non partitioned systems.
Each partition maps a set of power domains. Other than reading from
different MMIO regions, there is no change in the SST functionality.
The scope of SST control is still per power domain. Hence user space
does not need to be aware of existence of partitions.
With partitions, existing per package information defined using struct
tpmi_sst_struct is enhanced to store information for both partitions. A
mapping function map_partition_power_domain_id() is introduced, which
maps to correct partition and index. This mapping function is called
in get_instance() and isst_if_clos_assoc(), before indexing into
tpmi_sst_struct->power_domain_info[].
The TPMI core platform info provides partition id and compute die ID
mask for each partition. Use this information to order power domains,
so that compute dies are presented before IO dies to match hardware
defined compute die ID for each CPU.

The X1 carbon 2014 / 2nd gen's adaptive keyboard top row's "Home" mode,
which is 1 of the 2 modes Linux supports, has clipping-tool and cloud

I assume these were left as KEY_RESERVED because no suitable KEY_FOO codes

In the mean time we have gotten KEY_SELECTIVE_SCREENSHOT and this has been
used for the clipping-tool function under Fn + PrtSc on more traditional
ThinkPad keyboards already.
Finding a KEY_FOO code for the cloud key is harder looking at the symbol
it seems to refer to cloud-storage which made me think of file syncing,
or file transfer which has let me to pick KEY_XFER for this.
Note this is based on looking at a picture of the adaptive top row

on the input core filtering instead.
Also change tpacpi_input_send_key() to only report the scancode
once instead of reporting it on both press and release. Together
these 2 changes make tpacpi_input_send_key() behave the same as
sparse_keymap_report_event().
The goal of this patch is to have a separate commit with
the slightly different behavior from sparse_keymap_report_event()
before switching over to using the sparse-keymap helpers.

Change the default keymap to report the correct keycodes for the volume and
brightness keys. Reporting key events for these is already filtered out by
the hotkey_reserved_mask which masks these keys out of hotkey_user_mask at
initialization time, so there is no need to also map them to KEY_RESERVED.
This avoids users, who want these to be reported, having to also remap
the keycodes on top of overriding hotkey_user_mask to report these
and Linux userspace has already been overriding the KEY_RESERVED mappings
with the correct keycodes through udev/hwdb/60-keyboard.hwdb for years now.
Also drop hotkey_unmap() it was only used to dynamically map the brightness
keys to KEY_RESERVED and after removing that it has no remaining users.

Change the hotkey_reserved_mask initialization to hardcode the list
of reserved keys. There are only a few reserved keys and the code to
iterate over the keymap will be removed when moving to sparse-keymaps.
Note only the 32 original hotkeys are affected by the hotkey_*_mask values:
if (i < sizeof(hotkey_reserved_mask)*8)
hotkey_reserved_mask |= 1 << i;
The (i < sizeof(hotkey_reserved_mask)*8) condition translates to (i < 32)
so this code only ever set bits in hotkey_reserved_mask for the 32 original
hotkeys. Therefor this patch does not set any bits in hotkey_reserved_mask
for the KEY_RESERVED mappings for the adaptive keyboard scancodes.

Do not send ACPI netlink events for unknown hotkeys, to avoid userspace
starting to rely on them. Instead these should be added to the keymap to
send evdev events.
This should not cause a behavior change for existing laptop models since
all currently known 0x1xxx events have a mapping.
In hindsight the ACPI netlink events should have been suppressed for
the adaptive keyboard and extended hotkeys events too. But the kernel has
been sending ACPI netlink events for those for a long time now, so we
cannot just stop sending them without potentially causing issues for
existing users who may depend on these.

All callers of tpacpi_input_send_key() first call tpacpi_driver_event(),
move the tpacpi_driver_event() inside tpacpi_input_send_key() to avoid
code duplication.
For the original hotkey codes 0x1001 - 0x1020 tpacpi_driver_event() never
returns true. So the added "return true;" inside tpacpi_input_send_key()
never happens when called from tpacpi_hotkey_send_key() so behavior does
not change.

Move the mapping of hkey events to scancodes to tpacpi_input_send_key(),
this results in a nice cleanup and prepares things for adding sparse-keymap
support.

Call tpacpi_driver_event() at the top of hotkey_notify_hotkey() for all
(orig / adaptive / extended) hotkey types, rather then having the orig
code path call tpacpi_input_send_key_masked() which calls it through
hotkey_driver_event() and having the adaptive / extended helpers call
it separately.
