Dell hardware privacy implementation for dell laptop

|
From: Perry Yuan <perry_yuan@dell.com> Hi All, This patch set is a new driver for dell mobile platform ,which has the hardware privacy feature. For micmute led control, the hotkey is Fn + F4, it is a hardware based mute state, and new privacy will prevent micphone void input from hardware layer, any application cannot get voice data when micmute activated. Camera mute use a new hardware design to control the camrea shutter. When video is muted, no OS application should be functionally able to capture images of the person/environment in front of the system Older history: [1]https://patchwork.kernel.org/project/platform-driver-x86/patch/20201228132855.17544-1-Perry_Yuan@Dell.com/ [2]https://patchwork.kernel.org/project/alsa-devel/patch/20201103125859.8759-1-Perry_Yuan@Dell.com/#23733605 [3]https://www.spinics.net/lists/alsa-devel/msg120537.html [4]https://github.com/thesofproject/linux/pull/2660 Perry Yuan (3): platform/x86: dell-privacy: Add support for Dell hardware privacy x86/platform/dell-privacy-wmi: add document for dell privacy driver ASoC: rt715:add micmute led state control supports .../testing/sysfs-platform-dell-privacy-wmi | 31 ++ drivers/platform/x86/Kconfig | 17 + drivers/platform/x86/Makefile | 4 +- drivers/platform/x86/dell-laptop.c | 25 +- drivers/platform/x86/dell-privacy-acpi.c | 167 +++++++++ drivers/platform/x86/dell-privacy-wmi.c | 320 ++++++++++++++++++ drivers/platform/x86/dell-privacy-wmi.h | 33 ++ drivers/platform/x86/dell-wmi.c | 37 +- sound/soc/codecs/rt715-sdca.c | 16 + sound/soc/codecs/rt715-sdca.h | 1 + sound/soc/codecs/rt715.c | 14 + sound/soc/codecs/rt715.h | 1 + 12 files changed, 650 insertions(+), 16 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-dell-privacy-wmi create mode 100644 drivers/platform/x86/dell-privacy-acpi.c create mode 100644 drivers/platform/x86/dell-privacy-wmi.c create mode 100644 drivers/platform/x86/dell-privacy-wmi.h
