0f07c023dc platform/x86: dell-wmi-descriptor: disable by default
dell-wmi-descriptor only provides symbols to other drivers.
These drivers already select dell-wmi-descriptor when needed.

This fixes an issue where dell-wmi-descriptor is compiled as a module
with localyesconfig on a non-Dell machine.

92813dafcd platform/x86: dell: Make DELL_WMI_PRIVACY depend on DELL_WMI
DELL_WMI_PRIVACY is a feature toggle for the main dell-wmi driver,
so it must depend on the Kconfig option which enables the main
dell-wmi driver.

5b72dafaca platform/x86: dell: fix DELL_WMI_PRIVACY dependencies & build error
When DELL_WMI=y, DELL_WMI_PRIVACY=y, and LEDS_TRIGGER_AUDIO=m, there
is a linker error since the LEDS trigger code is built as a loadable
module. This happens because DELL_WMI_PRIVACY is a bool that depends
on a tristate (LEDS_TRIGGER_AUDIO=m), which can be dangerous.

ld: drivers/platform/x86/dell/dell-wmi-privacy.o: in function `dell_privacy_wmi_probe':
dell-wmi-privacy.c:(.text+0x3df): undefined reference to `ledtrig_audio_get'

bc6b8d7eec platform/x86: dell-smo8800: Convert to be a platform driver
ACPI core in conjunction with platform driver core provides
an infrastructure to enumerate ACPI devices. Use it in order
to remove a lot of boilerplate code.

3ece696c1a platform/x86: Remove "default n" entries
Linus already once did that for PDx86, don't repeat our mistakes.
TL;DR: 'n' *is* the default 'default'.

8af9fa37b8 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.

f1e1ea5167 platform/x86: Move all dell drivers to their own subdirectory
A user without a Dell system doesn't need to pick any of these
drivers.

Users with a Dell system can enable this submenu and all drivers
behind it will be enabled.
