platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from i2c-i801 to dell-lis3lv02d

platform/x86: dell-smo8800: Move instantiation of lis3lv02d i2c_client from i2c-i801 to dell-lis3lv02d

Various Dell laptops have an lis3lv02d freefall/accelerometer sensor.
The lis3lv02d chip has an interrupt line as well as an I2C connection to
the system's main SMBus.

The lis3lv02d is described in the ACPI tables by an SMO88xx ACPI device,
but the SMO88xx ACPI fwnodes are incomplete and only list an IRQ resource.

So far this has been worked around with some SMO88xx specific quirk code
in the generic i2c-i801 driver, but it is not necessary to handle the Dell
specific instantiation of i2c_client-s for SMO88xx ACPI devices there.

The kernel already instantiates platform_device-s for these with an
acpi:SMO88xx modalias. The drivers/platform/x86/dell/dell-smo8800.c
driver binds to this platform device but this only deals with
the interrupt resource. Add a drivers/platform/x86/dell/dell-lis3lv02d.c
which will matches on the same acpi:SMO88xx modaliases and move
the i2c_client instantiation from the generic i2c-i801 driver there.

Moving the i2c_client instantiation has the following advantages:

1. This moves the SMO88xx ACPI device quirk handling away from the generic
i2c-i801 module which is loaded on all Intel x86 machines to a module
which will only be loaded when there is an ACPI SMO88xx device.

2. This removes the duplication of the SMO88xx ACPI Hardware ID (HID) table
between the i2c-i801 and dell-smo8800 drivers.

3. This allows extending the quirk handling by adding new code and related
module parameters to the dell-lis3lv02d driver, without needing to modify
the i2c-i801 code.

platform/x86: Add new Dell UART backlight driver

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.

platform/x86: dell: Add new dell-wmi-ddv driver

The dell-wmi-ddv driver adds support for reading
the current temperature and ePPID of ACPI batteries
on supported Dell machines.

Since the WMI interface used by this driver does not
do any input validation and thus cannot be used for probing,
the driver depends on the ACPI battery extension machanism
to discover batteries.

The driver also supports a debugfs interface for retrieving
buffers containing fan and thermal sensor information.
Since the meaing of the content of those buffers is currently
unknown, the interface is meant for reverse-engineering and
will likely be replaced with an hwmon interface once the
meaning has been understood.

The driver was tested on a Dell Inspiron 3505.

platform/x86: dell-privacy: Add support for Dell hardware privacy

add support for Dell privacy driver for the Dell units equipped
hardware privacy design, which protect users privacy of audio and
camera from hardware level. Once the audio or camera privacy mode
activated, any applications will not get any audio or video stream
when user pressed ctrl+F4 hotkey, audio privacy mode will be
enabled, micmute led will be also changed accordingly
The micmute led is fully controlled by hardware & EC(embedded controller)
and camera mute hotkey is Ctrl+F9. Currently design only emits
SW_CAMERA_LENS_COVER event while the camera lens shutter will be
changed by EC & HW(hardware) control

*The flow is like this:
1) User presses key. HW does stuff with this key (timeout timer is started)
2) WMI event is emitted from BIOS to kernel
3) WMI event is received by dell-privacy
4) KEY_MICMUTE emitted from dell-privacy
5) Userland picks up key and modifies kcontrol for SW mute
6) Codec kernel driver catches and calls ledtrig_audio_set
7) dell-privacy notifies EC, the timeout is cancelled and the HW mute
is activated. If the EC is not notified then the HW mic mute will
activate when the timeout triggers, just a bit later than with the
active ack.
