This patch series adds support for the various features found on laptops manufactured by Uniwill. Those features are: - battery charge limiting - RGB lightbar control - hwmon support - improved hotkey support - keyboard-related settings This patch series is based on the following out-of-tree drivers: - https://github.com/pobrn/qc71_laptop - https://gitlab.com/tuxedocomputers/development/packages/tuxedo-drivers Additionally the OEM software of the Intel Nuc x15 was reverse-engineered to have a better understanding about the underlying hardware interface. The first patch introduces the uniwill-laptop driver that consists of two parts: a WMI part responsible for receiving platform events and a ACPI part that does the majority of the work by talking to the underlying embedded controller using the INOU0000 ACPI device. The whole driver uses a DMI whitelist for identifying supported notebook models as both the ACPI device ID and the WMI device GUID are shared with a wide range of notebook models that might use a different embedded controller register layout. The second patch additionally adds some documentation for configuring and using said driver. Special thanks go to: - github user cyear for bring up this topic on the lm-sensors issue tracker and being the tester for various prototype versions - github user dumingqiao for testing the battery, lightbar and keyboard-related features - Tuxedo computers for giving advice on how to design the userspace interface NOTE: During testing it turned out that the touchpad_toggle sysfs attribute does not work. The reason for this is unknown, as the driver emulates the behaviour of the OEM application just fine. I suspect that this feature only controls some obscure key combination we dont know about, so i decided to send out this series regardless. Changed since v2: - Use the INOU0000 ACPI device for talking to the EC as it is much faster than the WMI interface used before. Additionally the OEM application also uses this ACPI inteface through a special driver. - Merge the uniwill-wmi driver into the uniwill-laptop driver as the WMI driver should only load when matching the DMI whitelist. - Various small fixes Changes since v1: - spelling fixes - add missing error handling when reading PWM duty cycle - fix error when setting the super key lock sysfs attribute Changes since the RFC series: - spelling fixes - mention the INOU0000 ACPI device inside thew documentation - use MILLIDEGREE_PER_DEGREE instead of 1000 - use power_supply_get_property_direct() to prevent deadlock - add support for KEY_KBDILLUMDOWN and KEY_KBDILLUMUP Armin Wolf (2): platform/x86: Add Uniwill laptop driver Documentation: laptops: Add documentation for uniwill laptops .../ABI/testing/sysfs-driver-uniwill-laptop | 53 + Documentation/admin-guide/laptops/index.rst | 1 + .../admin-guide/laptops/uniwill-laptop.rst | 60 + Documentation/wmi/devices/uniwill-laptop.rst | 198 +++ MAINTAINERS | 11 + drivers/platform/x86/Kconfig | 2 + drivers/platform/x86/Makefile | 3 + drivers/platform/x86/uniwill/Kconfig | 38 + drivers/platform/x86/uniwill/Makefile | 8 + drivers/platform/x86/uniwill/uniwill-acpi.c | 1537 +++++++++++++++++ drivers/platform/x86/uniwill/uniwill-wmi.c | 92 + drivers/platform/x86/uniwill/uniwill-wmi.h | 127 ++ 12 files changed, 2130 insertions(+) create mode 100644 Documentation/ABI/testing/sysfs-driver-uniwill-laptop create mode 100644 Documentation/admin-guide/laptops/uniwill-laptop.rst create mode 100644 Documentation/wmi/devices/uniwill-laptop.rst create mode 100644 drivers/platform/x86/uniwill/Kconfig create mode 100644 drivers/platform/x86/uniwill/Makefile create mode 100644 drivers/platform/x86/uniwill/uniwill-acpi.c create mode 100644 drivers/platform/x86/uniwill/uniwill-wmi.c create mode 100644 drivers/platform/x86/uniwill/uniwill-wmi.h -- 2.39.5
